deform_autoneed 0.2b

Simple usage

During startup procedure of your app, simply run:

from deform_autoneed import includeme
includeme()

Or if you use the Pyramid framework:

config.include('deform_autoneed')

This will populate the local registry with any resources that deform widgets might need, and patch deforms render function so they’re included automatically.

And that’s it!

Using registered resources in other pages

deform prior to 2 depends on jquery, while deform 2 depends on jquery and bootstrap. If you want any of these base packages in any other view that isn’t a form, simply:

from deform_autoneed import need_lib

need_lib('basic')

Basic means any base requirements of deform itself. You may also call other deform dependencies here. Essentially, you can use any key from deforms default resource registry in: deform.widget.default_resources.

Replacing a resource requirement

If you wish to replace a resource with something else, ResourceRegistry has a method for that. It will have an effect on everything that might depend on that resource.

Example:

deforms form.css is a registered requirement. We’ll replace it with out own css, where our_css is a fanstatic resource object.

resource_registry.replace_resource('deform:static/css/form.css', our_css)

Note that replace_resource accepts either fanstatic.Resource``-objects or paths with package name, like ‘deform:static/css/form.css’ as arguments.

Registering a custom widgets resources

If you’re using any widgets/forms in deform that require non-standard plugins, you can register them within this package to include them.

First, create a Fanstatic library for your resources and an entry point in your setup.py. (See the Fanstatic docs for this)

from fanstatic import Library

my_lib = Library('my_lib', 'my/static')

Add your library to autoneed’s registry:

from deform_autoneed import resource_registry

resource_registry.libraries['my_package_name'] = my_lib

If you have structured your requirements the same way as in deform.widget.default_resources, and your directory for static resources is called static, you can call the method populate from resources to automatically create your package.

resource_registry.populate_from_resources(your_resources)

If not, you can simply add the requirements using the method create_requirement_for.

resource_registry.create_requirement_for('my_special_widget',
                                         ['my_package_name:my/static/css/cute.css', 'my_package_name:my/static/js/annoying.js'],
                                         )

In other words, this example had the directory layout, where the static directory is the base of your fanstatic library.

• my_package_name/

  • my/

    • static/

      • css/

      • js/

And the custom widget will require something called ‘my_special_widget’. (See the deform docs on custom widgets)

After this, your dependencies will be included automatically whenever deform needs them.

0.2b (2014-03-25)

• New methods to interact and replace resources.

• ResourceRegistry objects now keep track of fanstatic.Resources in ResourceRegistry.requirements, rather than file paths.

• create_requirement_for now figures out proper paths from fanstatic libraries, so just specify proper package paths like: package_name:some/dir/with/file.js.
