Customisable, modular user- and developer- friendly form builder application for Django
Project description
===============================================
django-fobi
===============================================
`django-fobi` (later on named just `fobi`) is a customisable, modular,
user- and developer- friendly form builder application for Django. With `fobi`
you can build Django forms using an intiutive GUI, save or mail posted form
data. API allows you to build your own form elements and form handlers
(mechanisms for handling the submitted form data).
Prerequisites
===============================================
- Django 1.5.+, 1.6.+
- Python 2.6.8+, 2.7.+, 3.3.+
Note, that Django 1.7 is not yet supported!
Key concepts
===============================================
- Each form consists of elements. Form elements are divided
into two groups:
- (a) form fields (input field, textarea, hidden field, file field, etc.).
- (b) content (presentational) elements (text, image, embed video, etc.).
- Number of form elements is not limited.
- Each form may contain handlers. Handler processes the form data (for example,
saves it or mails it). Number of the handlers is not limited.
- Both form elements and form handlers are made with Django permission system
in mind.
- As an addition to form handlers, form callbacks are implemented. Form
callbacks are fired on various stages of pre- and post-processing the form
data (on POST). Form callbacks do not make use of permission system (unless
you intentionally do so in the code of your callback) and are fired for all
forms (unlike form handlers, that are executed only if assigned).
- Each plugin (form element or form handler) or a callback - is a Django
micro-app.
Main features and highlights
===============================================
- User-friendly GUI to quickly build forms.
- Large variety of form elements/fields. Most of the Django fields are
supported. HTML5 fields are supported as well.
- In addition to standard form elements, there are cosmetic (presentational)
form elements (for adding a piece of text, image or a embed video)
alongside standard form elements.
- Data handling in plugins (form handlers). Save the data, mail it to some
address or repost it to some other endpoint.
- Developer-friendly API, which allows to or build new form fields and handlers
without touching the core.
- Support for custom user model.
- Theming. There are 3 ready to use themes bundled: Bootstrap 3, Foundation 5
and Simple (in style of Django admin).
- Implemented integration with FeinCMS (in a form of a FeinCMS Page widget).
- Reordering of form elements using drag-n-drop.
Roadmap
===============================================
Some of the upcoming/in-development features/improvements are:
- Django 1.7 support.
- Form importers (and as a part of it - MailChimp integration,
which would allow to import forms from MailChimp into Fobi using
a user-friendly wizard).
- Export data for the `db_store` plugin which would allow to
export saved form data as a CSV file.
- Fieldsets.
See the `TODOS <https://raw.githubusercontent.com/barseghyanartur/django-fobi/master/TODOS.rst>`_
for the full list of planned-, pending- in-development- or to-be-implemented
features.
Installation
===============================================
1. Install latest stable version from PyPI:
.. code-block:: none
$ pip install django-fobi
Or latest stable version from GitHub:
.. code-block:: none
$ pip install -e git+https://github.com/barseghyanartur/django-fobi@stable#egg=django-fobi
Or latest stable version from BitBucket:
.. code-block:: none
$ pip install -e hg+https://bitbucket.org/barseghyanartur/django-fobi@stable#egg=django-fobi
2. Add `fobi` to ``INSTALLED_APPS`` of the your projects' Django settings.
Furthermore, all themes and plugins to be used, shall be added to the
``INSTALLED_APPS`` as well.
.. code-block:: python
INSTALLED_APPS = (
# ...
# Fobi core
'fobi',
# Fobi themes
'fobi.contrib.themes.bootstrap3', # Bootstrap 3 theme
'fobi.contrib.themes.foundation5', # Foundation 5 theme
'fobi.contrib.themes.simple', # Simple theme
# Fobi form elements - fields
'fobi.contrib.plugins.form_elements.fields.boolean',
'fobi.contrib.plugins.form_elements.fields.date',
'fobi.contrib.plugins.form_elements.fields.datetime',
'fobi.contrib.plugins.form_elements.fields.email',
'fobi.contrib.plugins.form_elements.fields.file',
'fobi.contrib.plugins.form_elements.fields.hidden',
'fobi.contrib.plugins.form_elements.fields.integer',
'fobi.contrib.plugins.form_elements.fields.password',
'fobi.contrib.plugins.form_elements.fields.radio',
'fobi.contrib.plugins.form_elements.fields.select',
'fobi.contrib.plugins.form_elements.fields.select_model_object',
'fobi.contrib.plugins.form_elements.fields.select_multiple',
'fobi.contrib.plugins.form_elements.fields.text',
'fobi.contrib.plugins.form_elements.fields.textarea',
'fobi.contrib.plugins.form_elements.fields.url',
# Fobi form elements - content elements
'fobi.contrib.plugins.form_elements.content.dummy',
'fobi.contrib.plugins.form_elements.content.image',
'fobi.contrib.plugins.form_elements.content.text',
'fobi.contrib.plugins.form_elements.content.video',
# Form handlers
'fobi.contrib.plugins.form_handlers.db_store',
'fobi.contrib.plugins.form_handlers.http_repost',
'fobi.contrib.plugins.form_handlers.mail',
# Other project specific apps
'foo', # Test app
# ...
)
3. Make appropriate changes to the ``TEMPLATE_CONTEXT_PROCESSORS`` of the your
projects' Django settings.
And the following to the context processors.
.. code-block:: python
TEMPLATE_CONTEXT_PROCESSORS = (
# ...
"fobi.context_processors.theme".
# ...
)
Make sure that ``django.core.context_processors.request`` is in
``TEMPLATE_CONTEXT_PROCESSORS`` too.
4. Configure URLs
Add the following line to urlpatterns of your urls module.
.. code-block:: python
# View URLs
url(r'^fobi/', include('fobi.urls.view')),
# Edit URLs
url(r'^fobi/', include('fobi.urls.edit')),
View URLs are put separately from edit URLs in order to make it possible
to prefix the edit URLs differently. For example, if you're using the
"Simple" theme, you would likely want to prefix the edit URLs with "admin/"
so that it looks more like django-admin.
Demo
===============================================
See the documentation for some screen shots:
- PythonHosted http://pythonhosted.org/django-fobi/#screenshots
- ReadTheDocs http://django-fobi.readthedocs.org/en/latest/#screenshots
In order to be able to quickly evaluate the `Fobi`, a demo app (with a quick
installer) has been created (works on Ubuntu/Debian, may work on other Linux
systems as well, although not guaranteed). Follow the instructions below for
having the demo running within a minute.
Grab the latest `django_fobi_example_app_installer.sh`:
.. code-block:: none
$ wget https://raw.github.com/barseghyanartur/django-fobi/stable/examples/django_fobi_example_app_installer.sh
Assign execute rights to the installer and run the
`django_fobi_example_app_installer.sh`:
.. code-block:: none
$ chmod +x django_fobi_example_app_installer.sh
$ ./django_fobi_example_app_installer.sh
Open your browser and test the app.
Dashboard:
- URL: http://127.0.0.1:8001/fobi/
- Admin username: test_admin
- Admin password: test
Django admin interface:
- URL: http://127.0.0.1:8001/admin/
- Admin username: test_admin
- Admin password: test
If quick installer doesn't work for you, see the manual steps on running the
`example project <https://github.com/barseghyanartur/django-fobi/tree/stable/examples>`_.
Creating a new form element plugin
===============================================
Form element plugins represent the elements of which the forms is made:
Inputs, checkboxes, textareas, files, hidden fields, as well as pure
presentational elements (text or image). Number of form elements in a form
is not limited.
Presentational form elements are inherited from ``fobi.base.FormElementPlugin``.
The rest (real form elements, that are supposed to have a value)
are inherited from ``fobi.base.FormFieldPlugin``.
You should see a form element plugin as a Django micro app, which could have
its' own models, admin interface, etc.
Fobi comes with several bundled form element plugins. Do check the source code
as example.
Let's say, you want to create a textarea form element plugin.
There are several properties, each textarea should have. They are:
- `label` (string): HTML label of the textarea.
- `name` (string): HTML name of the textarea.
- `initial` (string): Initial value of the textarea.
- `required` (bool): Flag, which tells us whether the field is required or
optional.
Let's name that plugin `sample_textarea`. The plugin directory should then have
the following structure.
.. code-block:: none
path/to/sample_textarea/
├── __init__.py
├── fobi_form_elements.py # Where plugins are defined and registered
├── forms.py # Plugin configuration form
└── widgets.py # Where plugins widgets are defined
Form element plugins should be registered in "fobi_form_elements.py" file. Each
plugin module should be put into the ``INSTALLED_APPS`` of your Django
projects' settings.
In some cases, you would need plugin specific overridable settings (see
``fobi.contrib.form_elements.fields.content.image`` plugin as an example).
You are advised to write your settings in such a way, that variables of your
Django project settings module would have `FOBI_PLUGIN_` prefix.
Define and register the form element plugin
-----------------------------------------------
Step by step review of a how to create and register a plugin and plugin
widgets. Note, that Fobi autodiscovers your plugins if you place them into a
file named `fobi_form_elements.py` of any Django app listed in
``INSTALLED_APPS`` of your Django projects' settings module.
path/to/sample_textarea/fobi_form_elements.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A single form element plugin is registered by its' UID.
Required imports.
.. code-block:: python
from django import forms
from fobi.base import FormFieldPlugin, form_element_plugin_registry
from path.to.sample_textarea.forms import SampleTextareaForm
Defining the Sample textarea plugin.
.. code-block:: python
class SampleTextareaPlugin(FormFieldPlugin):
uid = "sample_textarea"
name = "Sample Textarea"
form = SampleTextareaForm
group = "Samples" # Group to which the plugin belongs to
def get_form_field_instances(self):
kwargs = {
'required': self.data.required,
'label': self.data.label,
'initial': self.data.initial,
'widget': forms.widgets.Textarea(attrs={})
}
return [(self.data.name, forms.CharField, kwargs),]
Registering the ``SampleTextareaPlugin`` plugin.
.. code-block:: python
form_element_plugin_registry.register(SampleTextareaPlugin)
Note, that in case you want to define a pure presentational element, make use
of ``fobi.base.FormElementPlugin`` for subclassing, instead of
``fobi.base.FormFieldPlugin``.
See the source of the content plugins
(fobi.contrib.plugins.form_elements.content) as a an example.
There might be cases, when you need to do additional handling of the data upon
the successful form submittion. In such cases, you will need to define a
``submit_plugin_form_data`` method in the plugin, which accepts the
following arguments:
- `form_entry` (fobi.models.FormEntry): Form entry, which is being submitted.
- `request` (django.http.HttpRequest): The Django HTTP request.
- `form` (django.forms.Form): Form object (a valid one, which contains
the ``cleaned_data`` attribute).
Example (taken from fobi.contrib.plugins.form_elements.fields.file):
.. code-block:: python
def submit_plugin_form_data(self, form_entry, request, form):
# Get the file path
file_path = form.cleaned_data.get(self.data.name, None)
if file_path:
# Handle the upload
saved_file = handle_uploaded_file(FILES_UPLOAD_DIR, file_path)
# Overwrite ``cleaned_data`` of the ``form`` with path to moved
# file.
form.cleaned_data[self.data.name] = "{0}{1}".format(
settings.MEDIA_URL, saved_file
)
# It's critically important to return the ``form`` with updated
# ``cleaned_data``
return form
In the example below, the original form is being modified. If you don't want
the original form to be modified, do not return anything.
Check the file form element plugin
(fobi.contrib.plugins.form_elements.fields.file) for complete example.
path/to/sample_textarea/forms.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Why to have another file for defining forms? Just to keep the code clean and
less messy, although you could perfectly define all your plugin forms in the
module `fobi_form_elements.py`, it's recommended to keep it separate.
Take into consideration, that `forms.py` is not an autodiscovered file pattern.
All your form element plugins should be registered in modules named
`fobi_form_elements.py`.
Required imports.
.. code-block:: python
from django import forms
from fobi.base import BasePluginForm
Form for for ``SampleTextareaPlugin`` form element plugin.
.. code-block:: python
class SampleTextareaForm(forms.Form, BasePluginForm):
plugin_data_fields = [
("name", ""),
("label", ""),
("initial", ""),
("required", False)
]
name = forms.CharField(label="Name", required=True)
label = forms.CharField(label="Label", required=True)
initial = forms.CharField(label="Initial", required=False)
required = forms.BooleanField(label="Required", required=False)
Note that although it's not being checked in the code, but for form
field plugins the following fields should be present in the plugin
form (``BasePluginForm``) and the form plugin (``FormFieldPlugin``):
- name
In some cases, you might want to do something with the data
before it gets saved. For that purpose, ``save_plugin_data`` method
has been introduced.
See the following `example <https://github.com/barseghyanartur/django-fobi/blob/stable/src/fobi/contrib/plugins/form_elements/content/image/forms.py>`_.
.. code-block:: python
def save_plugin_data(self, request=None):
"""
Saving the plugin data and moving the file.
"""
file_path = self.cleaned_data.get('file', None)
if file_path:
saved_image = handle_uploaded_file(IMAGES_UPLOAD_DIR, file_path)
self.cleaned_data['file'] = saved_image
path/to/sample_textarea/widgets.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Required imports.
.. code-block:: python
from fobi.base import FormElementPluginWidget
Defining the base plugin widget.
.. code-block:: python
class BaseSampleTextareaPluginWidget(FormElementPluginWidget):
# Same as ``uid`` value of the ``SampleTextareaPlugin``.
plugin_uid = "sample_textarea"
path/to/sample_layout/fobi_form_elements.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Register in the registry (in some module which is for sure to be loaded; it's
handy to do it in the theme module).
Required imports.
.. code-block:: python
from fobi.base import form_element_plugin_widget_registry
from path.to.sample_textarea.widgets import BaseSampleTextareaPluginWidget
Define the theme specific plugin.
.. code-block:: python
class SampleTextareaPluginWidget(BaseSampleTextareaPluginWidget):
theme_uid = 'bootstrap3' # Theme for which the widget is loaded
media_js = ['sample_layout/js/fobi.plugins.form_elements.sample_textarea.js',]
media_css = ['sample_layout/css/fobi.plugins.form_elements.sample_textarea.css',]
Register the widget.
.. code-block:: python
form_element_plugin_widget_registry.register(SampleTextareaPluginWidget)
Form element plugin final steps
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now, that everything is ready, make sure your plugin module is added to
``INSTALLED_APPS``.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.sample_textarea',
# ...
)
Afterwards, go to terminal and type the following command.
.. code-block:: none
$ ./manage.py fobi_sync_plugins
If your HTTP server is running, you would then be able to see the new plugin
in the edit form interface.
Dashboard URL: http://127.0.0.1:8000/fobi/
Note, that you have to be logged in, in order to use the dashboard. If your
new plugin doesn't appear, set the ``FOBI_DEBUG`` to True in your Django's
local settings module, re-run your code and check console for error
notifications.
Creating a new form handler plugin
===============================================
Form handler plugins handle the form data. Fobi comes with several bundled
form handler plugins, among which is the ``db_store`` and ``mail`` plugins,
which are responsible for saving the submitted form data into the database
and mailing the data to recipients specified. Number of form handlers in a
form is not limited. Certain form handlers are not configurable (for
example the ``db_store`` form handler isn't), while others are (``mail``,
``http_repost``).
You should see a form handler as a Django micro app, which could have its' own
models, admin interface, etc.
As said above, Fobi comes with several bundled form handler plugins. Do check
the source code as example.
Define and register the form handler plugin
-----------------------------------------------
Let's name that plugin `sample_mail`. The plugin directory should then have
the following structure.
.. code-block:: none
path/to/sample_mail/
├── __init__.py
├── fobi_form_handlers.py # Where plugins are defined and registered
└── forms.py # Plugin configuration form
Form handler plugins should be registered in "fobi_form_handlers.py" file.
Each plugin module should be put into the ``INSTALLED_APPS`` of your Django
projects' settings.
path/to/sample_mail/fobi_form_handlers.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A single form handler plugin is registered by its' UID.
Required imports.
.. code-block:: python
import json
from django.core.mail import send_mail
from fobi.base import FormHandlerPlugin, form_handler_plugin_registry
from path.to.sample_mail.forms import SampleMailForm
Defining the Sample mail handler plugin.
.. code-block:: python
class SampleMailHandlerPlugin(FormHandlerPlugin):
uid = "sample_mail"
name = _("Sample mail")
form = SampleMailForm
def run(self, form_entry, request, form):
send_mail(
self.data.subject,
json.dumps(form.cleaned_data),
self.data.from_email,
[self.data.to_email],
fail_silently = True
)
Some form handlers are configurable, some others not. In order to
have a user friendly way of showing the form handler settings, what's
sometimes needed, a ``plugin_data_repr`` method has been introducd.
Simplest implementation of it would look as follows:
.. code-block:: python
def plugin_data_repr(self):
"""
Human readable representation of plugin data.
:return string:
"""
return self.data.__dict__
path/to/sample_mail/forms.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If plugin is configurable, it has configuration data. A single form may have
unlimited number of same plugins. Imagine, you want to have different subjects
and additional body texts for different user groups. You could then assign two
form handler ``mail`` plugins to the form. Of course, saving the posted form
data many times does not make sense, but it's up to the user. So, in case if
plugin is configurable, it should have a form.
Why to have another file for defining forms? Just to keep the code clean and
less messy, although you could perfectly define all your plugin forms in the
module `fobi_form_handlers.py`, it's recommended to keep it separate.
Take into consideration, that `forms.py` is not an autodiscovered file pattern.
All your form handler plugins should be registered in modules named
`fobi_form_handlers.py`.
Required imports.
.. code-block:: python
from django import forms
from django.utils.translation import ugettext_lazy as _
from fobi.base import BasePluginForm
Defining the form for Sample mail handler plugin.
.. code-block:: python
class MailForm(forms.Form, BasePluginForm):
plugin_data_fields = [
("from_name", ""),
("from_email", ""),
("to_name", ""),
("to_email", ""),
("subject", ""),
("body", ""),
]
from_name = forms.CharField(label=_("From name"), required=True)
from_email = forms.EmailField(label=_("From email"), required=True)
to_name = forms.CharField(label=_("To name"), required=True)
to_email = forms.EmailField(label=_("To email"), required=True)
subject = forms.CharField(label=_("Subject"), required=True)
body = forms.CharField(label=_("Body"), required = False,
widget=forms.widgets.Textarea)
After the plugin has been processed, all its' data is available in a
``plugin_instance.data`` container (for example,
``plugin_instance.data.subject`` or ``plugin_instance.data.from_name``).
Prioritise the excecution order
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Some form handlers shall be executed prior others. A good example of such, is
a combination of "mail" and "db_save" form handlers for the form. In case of
large files posted, submittion of form data would fail if "mail" plugin would
be executed after "db_save" has been executed. That's why it's possible to
prioritise that ordering in a ``FOBI_FORM_HANDLER_PLUGINS_EXECUTION_ORDER``
setting variable.
If not specified or left empty, form handler plugins would be ran in the order
of discovery. All form handler plugins that are not listed in the
``FORM_HANDLER_PLUGINS_EXECUTION_ORDER``, would be ran after the plugins that
are mentioned there.
.. code-block:: python
FORM_HANDLER_PLUGINS_EXECUTION_ORDER = (
'http_repost',
'mail',
# The 'db_store' is left out intentionally, since it should
# be the last plugin to be executed.
)
Form handler plugin custom actions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By default, a single form handler plugin has at least a "delete" action.
If plugin is configurable, it gets an "edit" action as well.
For some of your plugins, you may want to register a custom action. For
example, the "db_store" plugin does have one, for showing a link to
a listing page with saved form data for the form given.
For such cases, define a ``custom_actions`` method in your form handler
plugin. That method shall return a list of triples. In each triple,
first value is the URL, second value is the title and the third value
is the icon of the URL.
The following example is taken from the "db_store" plugin.
.. code-block:: python
def custom_actions(self):
"""
Adding a link to view the saved form enties.
:return iterable:
"""
return (
(
reverse('fobi.contrib.plugins.form_handlers.db_store.view_saved_form_data_entries'),
_("View entries"),
'glyphicon glyphicon-list'
),
)
Form handler plugin final steps
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Do not forget to add the form handler plugin module to ``INSTALLED_APPS``.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.sample_mail',
# ...
)
Afterwards, go to terminal and type the following command.
.. code-block:: none
$ ./manage.py fobi_sync_plugins
If your HTTP server is running, you would then be able to see the new plugin
in the edit form interface.
Creating a form callback
===============================================
Form callbacks are additional hooks, that are executed on various stages of
the form submission.
Let's place the callback in the `foo` module. The plugin directory should then
have the following
structure.
.. code-block:: none
path/to/foo/
├── __init__.py
└── fobi_form_callbacks.py # Where callbacks are defined and registered
See the callback example below.
Required imports.
.. code-block:: python
from fobi.constants import (
CALLBACK_BEFORE_FORM_VALIDATION,
CALLBACK_FORM_VALID_BEFORE_SUBMIT_PLUGIN_FORM_DATA,
CALLBACK_FORM_VALID, CALLBACK_FORM_VALID_AFTER_FORM_HANDLERS,
CALLBACK_FORM_INVALID
)
from fobi.base import FormCallback, form_callback_registry
Define and register the callback
.. code-block:: python
class SampleFooCallback(FormCallback):
stage = CALLBACK_FORM_VALID
def callback(self, form_entry, request, form):
print("Great! Your form is valid!")
form_callback_registry.register(SampleFooCallback)
Add the callback module to ``INSTALLED_APPS``.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.foo',
# ...
)
Suggestions
===============================================
Custom action for the form
-----------------------------------------------
Sometimes, you would want to specify a different action for the form.
Although it's possible to define a custom form action (``action`` field
in the "Form properties" tab), you're advised to use the ``http_repost``
plugin instead, since then the form would be still validated locally
and only then the valid data, as is, would be sent to the desired
endpoint.
Take in mind, that if both cases, if CSRF protection is enabled on
the endpoint, your post request would result an error.
When you want to customise too many things
-----------------------------------------------
Fobi, with its' flexible form elements, form handlers and form callbacks
is very customisable. However, there might be cases when you need to
override entire view to fit your needs. Take a look at the
`FeinCMS integration <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/apps/feincms_integration/widgets.py>`_
as a good example of such. You may also want to compare the code from original
view ``fobi.views.view_form_entry`` with the code from the widget to get a
better idea of what could be changed in your case. If need a good advice,
just ask me.
Theming
===============================================
`Fobi` comes with theming API. While there are several ready-to-use themes:
- Bootstrap 3 theme
- Foundation 5 theme
- Simple theme in style of the Django admin
Have in mind, that creating a brand new theme could be time consuming.
Instead, you can create your own theme based on existing ones (just copy
the desired theme to your project directory and work it out further).
It's possible to use different templates for all "view" and "edit"
actions (see the source code of the "simple" theme). Both Bootstrap 3 and
Foundation 5 themes look great. Although if you can't use any of those,
the "simple" theme is the best start, since it looks just like django-admin.
Let's place the callback in the `foo` module. The plugin directory should then
have the following structure.
.. code-block:: none

view_form_entry_ajax_template = 'sample_theme/view_form_entry_ajax.html'
Registering the ``SampleTheme`` plugin.
.. code-block:: python
theme_registry.register(SampleTheme)
Sometimes you would want to attach additional properties to the theme
in order to use them later in templates (rememeber, current theme object
is always available in templates under name `fobi_theme`).
For such cases you would need to define a variable in your project's settings
module, called ``FOBI_CUSTOM_THEME_DATA``. See the following code as example:
.. code-block:: python
# Fobi custom theme data for to be displayed in third party apps
# like `django-registraton`.
FOBI_CUSTOM_THEME_DATA = {
'bootstrap3': {
'page_header_html_class': '',
'form_html_class': 'form-horizontal',
'form_button_outer_wrapper_html_class': 'control-group',
'form_button_wrapper_html_class': 'controls',
'form_button_html_class': 'btn',
'form_primary_button_html_class': 'btn-primary pull-right',
},
'foundation5': {
'page_header_html_class': '',
'form_html_class': 'form-horizontal',
'form_button_outer_wrapper_html_class': 'control-group',
'form_button_wrapper_html_class': 'controls',
'form_button_html_class': 'radius button',
'form_primary_button_html_class': 'btn-primary',
},
'simple': {
'page_header_html_class': '',
'form_html_class': 'form-horizontal',
'form_button_outer_wrapper_html_class': 'control-group',
'form_button_wrapper_html_class': 'submit-row',
'form_button_html_class': 'btn',
'form_primary_button_html_class': 'btn-primary',
}
}
You would now be able to access the defined extra properties in templates
as shown below.
.. code-block:: html
<div class="{{ fobi_theme.custom_data.form_button_wrapper_html_class }}">
You're like would want to either remove the footer text or change it. Define
a variable in your project's settings module, called ``FOBI_THEME_FOOTER_TEXT``.
See the following code as example:
.. code-block:: python
FOBI_THEME_FOOTER_TEXT = gettext('© django-fobi example site 2014')
Below follow the properties of the theme:
- ``base_edit``
- ``base_view``
There are generic templates made in order to simplify theming. Some
of them you would never need to override. Some others, you would likely
want to.
Templates that you likely would want to re-write in your custom
theme implemention are marked with three asterics (\*\*\*):
.. code-block:: none

From all of the templates listed above, the _base.html template is
the most influenced by the Bootstrap 3 theme.
Permissions
===============================================
Plugin system allows administrators to specify the access rights to every
plugin. Fobi permissions are based on Django Users and User Groups. Access
rights are managable via Django admin ("/admin/fobi/formelement/",
"/admin/fobi/formhandler/"). If user doesn't have the rights to access plugin,
it doesn't appear on his form even if has been added to it (imagine, you have
once granted the right to use the news plugin to all users, but later on
decided to limit it to Staff members group only). Note, that superusers have
access to all plugins.

Management commands
===============================================
There are several management commands available.
- `fobi_find_broken_entries`. Find broken form element/handler entries that
occur when some plugin which did exist in the system, no longer exists.
- `fobi_sync_plugins`. Should be ran each time a new plugin is being added to
the Fobi.
- `fobi_update_plugin_data`. A mechanism to update existing plugin data in
case if it had become invalid after a change in a plugin. In order for it
to work, each plugin should implement and ``update`` method, in which the
data update happens.
Tuning
===============================================
There are number of Dash settings you can override in the settings module of
your Django project:
- `FOBI_RESTRICT_PLUGIN_ACCESS` (bool): If set to True, (Django) permission
system for dash plugins is enabled. Defaults to True. Setting this to False
makes all plugins available for all users.
- `FOBI_DEFAULT_THEME` (str): Active (default) theme UID. Defaults to
"bootstrap3".
- `FORM_HANDLER_PLUGINS_EXECUTION_ORDER` (list of tuples): Order in which the
form handlers are executed. See the "Prioritise the excecution order"
section for details.
For tuning of specific contrib plugin, see the docs in the plugin directory.
Bundled plugins and themes
===============================================
Fobi ships with number of bundled form element- and form handler- plugins,
as well as themes which are ready to be used as is.

Debugging
===============================================
Most of the errors are logged (DEBUG). If you have written a plugin and it
somehow doesn't appear in the list of available plugins, do run the
./manage.py fobi_sync_plugins management command since it not only syncs your
plugins into the database, but also is a great way of checking for possible
errors.

django-fobi
===============================================
`django-fobi` (later on named just `fobi`) is a customisable, modular,
user- and developer- friendly form builder application for Django. With `fobi`
you can build Django forms using an intiutive GUI, save or mail posted form
data. API allows you to build your own form elements and form handlers
(mechanisms for handling the submitted form data).
Prerequisites
===============================================
- Django 1.5.+, 1.6.+
- Python 2.6.8+, 2.7.+, 3.3.+
Note, that Django 1.7 is not yet supported!
Key concepts
===============================================
- Each form consists of elements. Form elements are divided
into two groups:
- (a) form fields (input field, textarea, hidden field, file field, etc.).
- (b) content (presentational) elements (text, image, embed video, etc.).
- Number of form elements is not limited.
- Each form may contain handlers. Handler processes the form data (for example,
saves it or mails it). Number of the handlers is not limited.
- Both form elements and form handlers are made with Django permission system
in mind.
- As an addition to form handlers, form callbacks are implemented. Form
callbacks are fired on various stages of pre- and post-processing the form
data (on POST). Form callbacks do not make use of permission system (unless
you intentionally do so in the code of your callback) and are fired for all
forms (unlike form handlers, that are executed only if assigned).
- Each plugin (form element or form handler) or a callback - is a Django
micro-app.
Main features and highlights
===============================================
- User-friendly GUI to quickly build forms.
- Large variety of form elements/fields. Most of the Django fields are
supported. HTML5 fields are supported as well.
- In addition to standard form elements, there are cosmetic (presentational)
form elements (for adding a piece of text, image or a embed video)
alongside standard form elements.
- Data handling in plugins (form handlers). Save the data, mail it to some
address or repost it to some other endpoint.
- Developer-friendly API, which allows to or build new form fields and handlers
without touching the core.
- Support for custom user model.
- Theming. There are 3 ready to use themes bundled: Bootstrap 3, Foundation 5
and Simple (in style of Django admin).
- Implemented integration with FeinCMS (in a form of a FeinCMS Page widget).
- Reordering of form elements using drag-n-drop.
Roadmap
===============================================
Some of the upcoming/in-development features/improvements are:
- Django 1.7 support.
- Form importers (and as a part of it - MailChimp integration,
which would allow to import forms from MailChimp into Fobi using
a user-friendly wizard).
- Export data for the `db_store` plugin which would allow to
export saved form data as a CSV file.
- Fieldsets.
See the `TODOS <https://raw.githubusercontent.com/barseghyanartur/django-fobi/master/TODOS.rst>`_
for the full list of planned-, pending- in-development- or to-be-implemented
features.
Installation
===============================================
1. Install latest stable version from PyPI:
.. code-block:: none
$ pip install django-fobi
Or latest stable version from GitHub:
.. code-block:: none
$ pip install -e git+https://github.com/barseghyanartur/django-fobi@stable#egg=django-fobi
Or latest stable version from BitBucket:
.. code-block:: none
$ pip install -e hg+https://bitbucket.org/barseghyanartur/django-fobi@stable#egg=django-fobi
2. Add `fobi` to ``INSTALLED_APPS`` of the your projects' Django settings.
Furthermore, all themes and plugins to be used, shall be added to the
``INSTALLED_APPS`` as well.
.. code-block:: python
INSTALLED_APPS = (
# ...
# Fobi core
'fobi',
# Fobi themes
'fobi.contrib.themes.bootstrap3', # Bootstrap 3 theme
'fobi.contrib.themes.foundation5', # Foundation 5 theme
'fobi.contrib.themes.simple', # Simple theme
# Fobi form elements - fields
'fobi.contrib.plugins.form_elements.fields.boolean',
'fobi.contrib.plugins.form_elements.fields.date',
'fobi.contrib.plugins.form_elements.fields.datetime',
'fobi.contrib.plugins.form_elements.fields.email',
'fobi.contrib.plugins.form_elements.fields.file',
'fobi.contrib.plugins.form_elements.fields.hidden',
'fobi.contrib.plugins.form_elements.fields.integer',
'fobi.contrib.plugins.form_elements.fields.password',
'fobi.contrib.plugins.form_elements.fields.radio',
'fobi.contrib.plugins.form_elements.fields.select',
'fobi.contrib.plugins.form_elements.fields.select_model_object',
'fobi.contrib.plugins.form_elements.fields.select_multiple',
'fobi.contrib.plugins.form_elements.fields.text',
'fobi.contrib.plugins.form_elements.fields.textarea',
'fobi.contrib.plugins.form_elements.fields.url',
# Fobi form elements - content elements
'fobi.contrib.plugins.form_elements.content.dummy',
'fobi.contrib.plugins.form_elements.content.image',
'fobi.contrib.plugins.form_elements.content.text',
'fobi.contrib.plugins.form_elements.content.video',
# Form handlers
'fobi.contrib.plugins.form_handlers.db_store',
'fobi.contrib.plugins.form_handlers.http_repost',
'fobi.contrib.plugins.form_handlers.mail',
# Other project specific apps
'foo', # Test app
# ...
)
3. Make appropriate changes to the ``TEMPLATE_CONTEXT_PROCESSORS`` of the your
projects' Django settings.
And the following to the context processors.
.. code-block:: python
TEMPLATE_CONTEXT_PROCESSORS = (
# ...
"fobi.context_processors.theme".
# ...
)
Make sure that ``django.core.context_processors.request`` is in
``TEMPLATE_CONTEXT_PROCESSORS`` too.
4. Configure URLs
Add the following line to urlpatterns of your urls module.
.. code-block:: python
# View URLs
url(r'^fobi/', include('fobi.urls.view')),
# Edit URLs
url(r'^fobi/', include('fobi.urls.edit')),
View URLs are put separately from edit URLs in order to make it possible
to prefix the edit URLs differently. For example, if you're using the
"Simple" theme, you would likely want to prefix the edit URLs with "admin/"
so that it looks more like django-admin.
Demo
===============================================
See the documentation for some screen shots:
- PythonHosted http://pythonhosted.org/django-fobi/#screenshots
- ReadTheDocs http://django-fobi.readthedocs.org/en/latest/#screenshots
In order to be able to quickly evaluate the `Fobi`, a demo app (with a quick
installer) has been created (works on Ubuntu/Debian, may work on other Linux
systems as well, although not guaranteed). Follow the instructions below for
having the demo running within a minute.
Grab the latest `django_fobi_example_app_installer.sh`:
.. code-block:: none
$ wget https://raw.github.com/barseghyanartur/django-fobi/stable/examples/django_fobi_example_app_installer.sh
Assign execute rights to the installer and run the
`django_fobi_example_app_installer.sh`:
.. code-block:: none
$ chmod +x django_fobi_example_app_installer.sh
$ ./django_fobi_example_app_installer.sh
Open your browser and test the app.
Dashboard:
- URL: http://127.0.0.1:8001/fobi/
- Admin username: test_admin
- Admin password: test
Django admin interface:
- URL: http://127.0.0.1:8001/admin/
- Admin username: test_admin
- Admin password: test
If quick installer doesn't work for you, see the manual steps on running the
`example project <https://github.com/barseghyanartur/django-fobi/tree/stable/examples>`_.
Creating a new form element plugin
===============================================
Form element plugins represent the elements of which the forms is made:
Inputs, checkboxes, textareas, files, hidden fields, as well as pure
presentational elements (text or image). Number of form elements in a form
is not limited.
Presentational form elements are inherited from ``fobi.base.FormElementPlugin``.
The rest (real form elements, that are supposed to have a value)
are inherited from ``fobi.base.FormFieldPlugin``.
You should see a form element plugin as a Django micro app, which could have
its' own models, admin interface, etc.
Fobi comes with several bundled form element plugins. Do check the source code
as example.
Let's say, you want to create a textarea form element plugin.
There are several properties, each textarea should have. They are:
- `label` (string): HTML label of the textarea.
- `name` (string): HTML name of the textarea.
- `initial` (string): Initial value of the textarea.
- `required` (bool): Flag, which tells us whether the field is required or
optional.
Let's name that plugin `sample_textarea`. The plugin directory should then have
the following structure.

Form element plugins should be registered in "fobi_form_elements.py" file. Each
plugin module should be put into the ``INSTALLED_APPS`` of your Django
projects' settings.
In some cases, you would need plugin specific overridable settings (see
``fobi.contrib.form_elements.fields.content.image`` plugin as an example).
You are advised to write your settings in such a way, that variables of your
Django project settings module would have `FOBI_PLUGIN_` prefix.
Define and register the form element plugin
-----------------------------------------------
Step by step review of a how to create and register a plugin and plugin
widgets. Note, that Fobi autodiscovers your plugins if you place them into a
file named `fobi_form_elements.py` of any Django app listed in
``INSTALLED_APPS`` of your Django projects' settings module.
path/to/sample_textarea/fobi_form_elements.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A single form element plugin is registered by its' UID.
Required imports.
.. code-block:: python
from django import forms
from fobi.base import FormFieldPlugin, form_element_plugin_registry
from path.to.sample_textarea.forms import SampleTextareaForm
Defining the Sample textarea plugin.
.. code-block:: python
class SampleTextareaPlugin(FormFieldPlugin):
uid = "sample_textarea"
name = "Sample Textarea"
form = SampleTextareaForm
group = "Samples" # Group to which the plugin belongs to
def get_form_field_instances(self):
kwargs = {
'required': self.data.required,
'label': self.data.label,
'initial': self.data.initial,
'widget': forms.widgets.Textarea(attrs={})
}
return [(self.data.name, forms.CharField, kwargs),]
Registering the ``SampleTextareaPlugin`` plugin.
.. code-block:: python
form_element_plugin_registry.register(SampleTextareaPlugin)
Note, that in case you want to define a pure presentational element, make use
of ``fobi.base.FormElementPlugin`` for subclassing, instead of
``fobi.base.FormFieldPlugin``.
See the source of the content plugins
(fobi.contrib.plugins.form_elements.content) as a an example.
There might be cases, when you need to do additional handling of the data upon
the successful form submittion. In such cases, you will need to define a
``submit_plugin_form_data`` method in the plugin, which accepts the
following arguments:
- `form_entry` (fobi.models.FormEntry): Form entry, which is being submitted.
- `request` (django.http.HttpRequest): The Django HTTP request.
- `form` (django.forms.Form): Form object (a valid one, which contains
the ``cleaned_data`` attribute).
Example (taken from fobi.contrib.plugins.form_elements.fields.file):
.. code-block:: python
def submit_plugin_form_data(self, form_entry, request, form):
# Get the file path
file_path = form.cleaned_data.get(self.data.name, None)
if file_path:
# Handle the upload
saved_file = handle_uploaded_file(FILES_UPLOAD_DIR, file_path)
# Overwrite ``cleaned_data`` of the ``form`` with path to moved
# file.
form.cleaned_data[self.data.name] = "{0}{1}".format(
settings.MEDIA_URL, saved_file
)
# It's critically important to return the ``form`` with updated
# ``cleaned_data``
return form
In the example below, the original form is being modified. If you don't want
the original form to be modified, do not return anything.
Check the file form element plugin
(fobi.contrib.plugins.form_elements.fields.file) for complete example.
path/to/sample_textarea/forms.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Why to have another file for defining forms? Just to keep the code clean and
less messy, although you could perfectly define all your plugin forms in the
module `fobi_form_elements.py`, it's recommended to keep it separate.
Take into consideration, that `forms.py` is not an autodiscovered file pattern.
All your form element plugins should be registered in modules named
`fobi_form_elements.py`.
Required imports.
.. code-block:: python
from django import forms
from fobi.base import BasePluginForm
Form for for ``SampleTextareaPlugin`` form element plugin.
.. code-block:: python
class SampleTextareaForm(forms.Form, BasePluginForm):
plugin_data_fields = [
("name", ""),
("label", ""),
("initial", ""),
("required", False)
]
name = forms.CharField(label="Name", required=True)
label = forms.CharField(label="Label", required=True)
initial = forms.CharField(label="Initial", required=False)
required = forms.BooleanField(label="Required", required=False)
Note that although it's not being checked in the code, but for form
field plugins the following fields should be present in the plugin
form (``BasePluginForm``) and the form plugin (``FormFieldPlugin``):
- name
In some cases, you might want to do something with the data
before it gets saved. For that purpose, ``save_plugin_data`` method
has been introduced.
See the following `example <https://github.com/barseghyanartur/django-fobi/blob/stable/src/fobi/contrib/plugins/form_elements/content/image/forms.py>`_.
.. code-block:: python
def save_plugin_data(self, request=None):
"""
Saving the plugin data and moving the file.
"""
file_path = self.cleaned_data.get('file', None)
if file_path:
saved_image = handle_uploaded_file(IMAGES_UPLOAD_DIR, file_path)
self.cleaned_data['file'] = saved_image
path/to/sample_textarea/widgets.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Required imports.
.. code-block:: python
from fobi.base import FormElementPluginWidget
Defining the base plugin widget.
.. code-block:: python
class BaseSampleTextareaPluginWidget(FormElementPluginWidget):
# Same as ``uid`` value of the ``SampleTextareaPlugin``.
plugin_uid = "sample_textarea"
path/to/sample_layout/fobi_form_elements.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Register in the registry (in some module which is for sure to be loaded; it's
handy to do it in the theme module).
Required imports.
.. code-block:: python
from fobi.base import form_element_plugin_widget_registry
from path.to.sample_textarea.widgets import BaseSampleTextareaPluginWidget
Define the theme specific plugin.
.. code-block:: python
class SampleTextareaPluginWidget(BaseSampleTextareaPluginWidget):
theme_uid = 'bootstrap3' # Theme for which the widget is loaded
media_js = ['sample_layout/js/fobi.plugins.form_elements.sample_textarea.js',]
media_css = ['sample_layout/css/fobi.plugins.form_elements.sample_textarea.css',]
Register the widget.
.. code-block:: python
form_element_plugin_widget_registry.register(SampleTextareaPluginWidget)
Form element plugin final steps
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now, that everything is ready, make sure your plugin module is added to
``INSTALLED_APPS``.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.sample_textarea',
# ...
)
Afterwards, go to terminal and type the following command.
.. code-block:: none
$ ./manage.py fobi_sync_plugins
If your HTTP server is running, you would then be able to see the new plugin
in the edit form interface.
Dashboard URL: http://127.0.0.1:8000/fobi/
Note, that you have to be logged in, in order to use the dashboard. If your
new plugin doesn't appear, set the ``FOBI_DEBUG`` to True in your Django's
local settings module, re-run your code and check console for error
notifications.
Creating a new form handler plugin
===============================================
Form handler plugins handle the form data. Fobi comes with several bundled
form handler plugins, among which is the ``db_store`` and ``mail`` plugins,
which are responsible for saving the submitted form data into the database
and mailing the data to recipients specified. Number of form handlers in a
form is not limited. Certain form handlers are not configurable (for
example the ``db_store`` form handler isn't), while others are (``mail``,
``http_repost``).
You should see a form handler as a Django micro app, which could have its' own
models, admin interface, etc.
As said above, Fobi comes with several bundled form handler plugins. Do check
the source code as example.
Define and register the form handler plugin
-----------------------------------------------
Let's name that plugin `sample_mail`. The plugin directory should then have
the following structure.
.. code-block:: none
path/to/sample_mail/
├── __init__.py
├── fobi_form_handlers.py # Where plugins are defined and registered
└── forms.py # Plugin configuration form
Form handler plugins should be registered in "fobi_form_handlers.py" file.
Each plugin module should be put into the ``INSTALLED_APPS`` of your Django
projects' settings.
path/to/sample_mail/fobi_form_handlers.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A single form handler plugin is registered by its' UID.
Required imports.
.. code-block:: python
import json
from django.core.mail import send_mail
from fobi.base import FormHandlerPlugin, form_handler_plugin_registry
from path.to.sample_mail.forms import SampleMailForm
Defining the Sample mail handler plugin.
.. code-block:: python
class SampleMailHandlerPlugin(FormHandlerPlugin):
uid = "sample_mail"
name = _("Sample mail")
form = SampleMailForm
def run(self, form_entry, request, form):
send_mail(
self.data.subject,
json.dumps(form.cleaned_data),
self.data.from_email,
[self.data.to_email],
fail_silently = True
)
Some form handlers are configurable, some others not. In order to
have a user friendly way of showing the form handler settings, what's
sometimes needed, a ``plugin_data_repr`` method has been introducd.
Simplest implementation of it would look as follows:
.. code-block:: python
def plugin_data_repr(self):
"""
Human readable representation of plugin data.
:return string:
"""
return self.data.__dict__
path/to/sample_mail/forms.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If plugin is configurable, it has configuration data. A single form may have
unlimited number of same plugins. Imagine, you want to have different subjects
and additional body texts for different user groups. You could then assign two
form handler ``mail`` plugins to the form. Of course, saving the posted form
data many times does not make sense, but it's up to the user. So, in case if
plugin is configurable, it should have a form.
Why to have another file for defining forms? Just to keep the code clean and
less messy, although you could perfectly define all your plugin forms in the
module `fobi_form_handlers.py`, it's recommended to keep it separate.
Take into consideration, that `forms.py` is not an autodiscovered file pattern.
All your form handler plugins should be registered in modules named
`fobi_form_handlers.py`.
Required imports.
.. code-block:: python
from django import forms
from django.utils.translation import ugettext_lazy as _
from fobi.base import BasePluginForm
Defining the form for Sample mail handler plugin.
.. code-block:: python
class MailForm(forms.Form, BasePluginForm):
plugin_data_fields = [
("from_name", ""),
("from_email", ""),
("to_name", ""),
("to_email", ""),
("subject", ""),
("body", ""),
]
from_name = forms.CharField(label=_("From name"), required=True)
from_email = forms.EmailField(label=_("From email"), required=True)
to_name = forms.CharField(label=_("To name"), required=True)
to_email = forms.EmailField(label=_("To email"), required=True)
subject = forms.CharField(label=_("Subject"), required=True)
body = forms.CharField(label=_("Body"), required = False,
widget=forms.widgets.Textarea)
After the plugin has been processed, all its' data is available in a
``plugin_instance.data`` container (for example,
``plugin_instance.data.subject`` or ``plugin_instance.data.from_name``).
Prioritise the excecution order
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Some form handlers shall be executed prior others. A good example of such, is
a combination of "mail" and "db_save" form handlers for the form. In case of
large files posted, submittion of form data would fail if "mail" plugin would
be executed after "db_save" has been executed. That's why it's possible to
prioritise that ordering in a ``FOBI_FORM_HANDLER_PLUGINS_EXECUTION_ORDER``
setting variable.
If not specified or left empty, form handler plugins would be ran in the order
of discovery. All form handler plugins that are not listed in the
``FORM_HANDLER_PLUGINS_EXECUTION_ORDER``, would be ran after the plugins that
are mentioned there.
.. code-block:: python
FORM_HANDLER_PLUGINS_EXECUTION_ORDER = (
'http_repost',
'mail',
# The 'db_store' is left out intentionally, since it should
# be the last plugin to be executed.
)
Form handler plugin custom actions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By default, a single form handler plugin has at least a "delete" action.
If plugin is configurable, it gets an "edit" action as well.
For some of your plugins, you may want to register a custom action. For
example, the "db_store" plugin does have one, for showing a link to
a listing page with saved form data for the form given.
For such cases, define a ``custom_actions`` method in your form handler
plugin. That method shall return a list of triples. In each triple,
first value is the URL, second value is the title and the third value
is the icon of the URL.
The following example is taken from the "db_store" plugin.
.. code-block:: python
def custom_actions(self):
"""
Adding a link to view the saved form enties.
:return iterable:
"""
return (
(
reverse('fobi.contrib.plugins.form_handlers.db_store.view_saved_form_data_entries'),
_("View entries"),
'glyphicon glyphicon-list'
),
)
Form handler plugin final steps
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Do not forget to add the form handler plugin module to ``INSTALLED_APPS``.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.sample_mail',
# ...
)
Afterwards, go to terminal and type the following command.
.. code-block:: none
$ ./manage.py fobi_sync_plugins
If your HTTP server is running, you would then be able to see the new plugin
in the edit form interface.
Creating a form callback
===============================================
Form callbacks are additional hooks, that are executed on various stages of
the form submission.
Let's place the callback in the `foo` module. The plugin directory should then
have the following
structure.
.. code-block:: none
path/to/foo/
├── __init__.py
└── fobi_form_callbacks.py # Where callbacks are defined and registered
See the callback example below.
Required imports.
.. code-block:: python
from fobi.constants import (
CALLBACK_BEFORE_FORM_VALIDATION,
CALLBACK_FORM_VALID_BEFORE_SUBMIT_PLUGIN_FORM_DATA,
CALLBACK_FORM_VALID, CALLBACK_FORM_VALID_AFTER_FORM_HANDLERS,
CALLBACK_FORM_INVALID
)
from fobi.base import FormCallback, form_callback_registry
Define and register the callback
.. code-block:: python
class SampleFooCallback(FormCallback):
stage = CALLBACK_FORM_VALID
def callback(self, form_entry, request, form):
print("Great! Your form is valid!")
form_callback_registry.register(SampleFooCallback)
Add the callback module to ``INSTALLED_APPS``.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.foo',
# ...
)
Suggestions
===============================================
Custom action for the form
-----------------------------------------------
Sometimes, you would want to specify a different action for the form.
Although it's possible to define a custom form action (``action`` field
in the "Form properties" tab), you're advised to use the ``http_repost``
plugin instead, since then the form would be still validated locally
and only then the valid data, as is, would be sent to the desired
endpoint.
Take in mind, that if both cases, if CSRF protection is enabled on
the endpoint, your post request would result an error.
When you want to customise too many things
-----------------------------------------------
Fobi, with its' flexible form elements, form handlers and form callbacks
is very customisable. However, there might be cases when you need to
override entire view to fit your needs. Take a look at the
`FeinCMS integration <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/apps/feincms_integration/widgets.py>`_
as a good example of such. You may also want to compare the code from original
view ``fobi.views.view_form_entry`` with the code from the widget to get a
better idea of what could be changed in your case. If need a good advice,
just ask me.
Theming
===============================================
`Fobi` comes with theming API. While there are several ready-to-use themes:
- Bootstrap 3 theme
- Foundation 5 theme
- Simple theme in style of the Django admin
Have in mind, that creating a brand new theme could be time consuming.
Instead, you can create your own theme based on existing ones (just copy
the desired theme to your project directory and work it out further).
It's possible to use different templates for all "view" and "edit"
actions (see the source code of the "simple" theme). Both Bootstrap 3 and
Foundation 5 themes look great. Although if you can't use any of those,
the "simple" theme is the best start, since it looks just like django-admin.
Let's place the callback in the `foo` module. The plugin directory should then
have the following structure.
.. code-block:: none
path/to/sample_theme/
├── static
│ ├── css
│ │ └── sample_theme.css

view_form_entry_ajax_template = 'sample_theme/view_form_entry_ajax.html'
Registering the ``SampleTheme`` plugin.
.. code-block:: python
theme_registry.register(SampleTheme)
Sometimes you would want to attach additional properties to the theme
in order to use them later in templates (rememeber, current theme object
is always available in templates under name `fobi_theme`).
For such cases you would need to define a variable in your project's settings
module, called ``FOBI_CUSTOM_THEME_DATA``. See the following code as example:
.. code-block:: python
# Fobi custom theme data for to be displayed in third party apps
# like `django-registraton`.
FOBI_CUSTOM_THEME_DATA = {
'bootstrap3': {
'page_header_html_class': '',
'form_html_class': 'form-horizontal',
'form_button_outer_wrapper_html_class': 'control-group',
'form_button_wrapper_html_class': 'controls',
'form_button_html_class': 'btn',
'form_primary_button_html_class': 'btn-primary pull-right',
},
'foundation5': {
'page_header_html_class': '',
'form_html_class': 'form-horizontal',
'form_button_outer_wrapper_html_class': 'control-group',
'form_button_wrapper_html_class': 'controls',
'form_button_html_class': 'radius button',
'form_primary_button_html_class': 'btn-primary',
},
'simple': {
'page_header_html_class': '',
'form_html_class': 'form-horizontal',
'form_button_outer_wrapper_html_class': 'control-group',
'form_button_wrapper_html_class': 'submit-row',
'form_button_html_class': 'btn',
'form_primary_button_html_class': 'btn-primary',
}
}
You would now be able to access the defined extra properties in templates
as shown below.
.. code-block:: html
<div class="{{ fobi_theme.custom_data.form_button_wrapper_html_class }}">
You're like would want to either remove the footer text or change it. Define
a variable in your project's settings module, called ``FOBI_THEME_FOOTER_TEXT``.
See the following code as example:
.. code-block:: python
FOBI_THEME_FOOTER_TEXT = gettext('© django-fobi example site 2014')
Below follow the properties of the theme:
- ``base_edit``
- ``base_view``
There are generic templates made in order to simplify theming. Some
of them you would never need to override. Some others, you would likely
want to.
Templates that you likely would want to re-write in your custom
theme implemention are marked with three asterics (\*\*\*):
.. code-block:: none

Permissions
===============================================
Plugin system allows administrators to specify the access rights to every
plugin. Fobi permissions are based on Django Users and User Groups. Access
rights are managable via Django admin ("/admin/fobi/formelement/",
"/admin/fobi/formhandler/"). If user doesn't have the rights to access plugin,
it doesn't appear on his form even if has been added to it (imagine, you have
once granted the right to use the news plugin to all users, but later on
decided to limit it to Staff members group only). Note, that superusers have
access to all plugins.

Management commands
===============================================
There are several management commands available.
- `fobi_find_broken_entries`. Find broken form element/handler entries that
occur when some plugin which did exist in the system, no longer exists.
- `fobi_sync_plugins`. Should be ran each time a new plugin is being added to
the Fobi.
- `fobi_update_plugin_data`. A mechanism to update existing plugin data in
case if it had become invalid after a change in a plugin. In order for it
to work, each plugin should implement and ``update`` method, in which the
data update happens.
Tuning
===============================================
There are number of Dash settings you can override in the settings module of
your Django project:
- `FOBI_RESTRICT_PLUGIN_ACCESS` (bool): If set to True, (Django) permission
system for dash plugins is enabled. Defaults to True. Setting this to False
makes all plugins available for all users.
- `FOBI_DEFAULT_THEME` (str): Active (default) theme UID. Defaults to
"bootstrap3".
- `FORM_HANDLER_PLUGINS_EXECUTION_ORDER` (list of tuples): Order in which the
form handlers are executed. See the "Prioritise the excecution order"
section for details.
For tuning of specific contrib plugin, see the docs in the plugin directory.
Bundled plugins and themes
===============================================
Fobi ships with number of bundled form element- and form handler- plugins,
as well as themes which are ready to be used as is.
Bundled form element plugins

Below a short overview of the form element plugins. See the README.rst file
in directory of each plugin for details.

Debugging
===============================================
Most of the errors are logged (DEBUG). If you have written a plugin and it
somehow doesn't appear in the list of available plugins, do run the
./manage.py fobi_sync_plugins management command since it not only syncs your
plugins into the database, but also is a great way of checking for possible
errors.
