django-easy-select2 1.1.1

Installation

1. install this package as usual, using python setup.py install, pip install django-easy-select2 or download sources and install to your python path.

2. add easy_select2 to INSTALLED_APPS in your settings.py

3. Use python manage.py collectstatic or manually copy easy_select2’s static directory to your project’s static directory (if you serve your static with nginx, for example).

4. Modify your admin.py.

5. Check out admin in browser.

Configuration

django-easy-select2 bundles jquery and select2 static files. You can use them, or specify your own files to include in widget.

To use bundled static, just install an application.

To use your custom static files, you can specify next settings in your settings.py:

• SELECT2_JS - path to select2.js file. Specify path without static directory, because full URL will be interpolated using static function from staticfiles application. Default: easy_select2/vendor/select2/select2.min.js

• SELECT2_CSS - path to select2.css file. Default: easy_select2/vendor/select2/select2.min.css

• SELECT2_USE_BUNDLED_JQUERY - default is True. Set to False if your already have included custom jQuery.

Quickstart

In your admin.py:

from django.contrib import admin
from easy_select2 import select2_modelform
from polls.models import Poll

PollForm = select2_modelform(Poll, attrs={'width': '250px'})

class PollAdmin(admin.ModelAdmin):
    form = PollAdmin

Thats all. All your choice widgets are select2 widgets 250px wide.

Usage

There are Select2 and Select2Multiple widget classes. You can use them on any form field, as usual django widget:

class Form(forms.Form):
    field = forms.ModelChoiceField(queryset=qs, widget=Select2())

or:

class Form(forms.Form):
    field = forms.ModelChoiceField(queryset=qs, widget=Select2Multiple(
        select2attrs={'width': 'auto'}
    ))

Select2 and Select2Multiple is simple classes build with Select2Mixin:

class Select2Multiple(Select2Mixin, forms.SelectMultiple):
    pass

class Select2(Select2Mixin, forms.Select):
    pass

Select2Mixin is a simple widget mixin with predefined Media class and custom render method, which applies $.fn.select2() method on html input.

If you want to use it with all form fields automatically, without specifying each field, you can create your ModelForm class with Meta class constructed by custom Meta factory:

from easy_select2 import select2_modelform_meta

class SomeModelForm(forms.ModelForm):
    Meta = select2_modelform_meta(SomeModel)

select2_modelform_meta is a simple factory, that produces a Meta class with model attribute set to specified model and widgets attribute set to dictionary, containing all selectable fields on model. Every selectable field will be converted from standard widget to Select2 or Select2Multiple widget.

If you are lazy, you can use ModelForm factory to build ready-to-use ModelForm for model:

from easy_select2 import select2_modelform

MyModelForm = select2_modelform(MyModel)

is the same like:

class MyModelForm(forms.ModelForm):
    Meta = select2_modelform_meta(models.SomeModelForm)

MyModelForm is an instance of ModelForm with model attribute set to MyModel, and appropriate Meta class.

There is also an apply_select2 function that dynamically creates new widget class mixed with Select2Mixin.

Usage, for example:

class SomeModelForm(admin.ModelForm):
    class Meta:
        widgets = {
            'field': apply_select2(forms.Select),
        }

So, apply_select2(forms.Select) will return new class, named Select2Select, mixed with Select2Mixin.
