Cleaned up and refactored `ModelAdmin.formfield_for_dbfield`:
* The new method uses an admin configuration option (`formfield_overrides`); this makes custom admin widgets especially easy. * Refactored what was left of `formfield_for_dbfield` into a handful of smaller methods so that it's easier to hook in and return custom fields where needed. * These `formfield_for_*` methods now pass around `request` so that you can easily modify fields based on request (as in #3987). Fixes #8306, #3987, #9148. Thanks to James Bennet for the original patch; Alex Gaynor and Brian Rosner also contributed. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9760 bcc190cf-cafb-0310-a4f2-bffc1f526a37

``formfield_overrides``
|
||||
~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
This provides a quick-and-dirty way to override some of the
|
||||
:class:`~django.forms.Field` options for use in the admin.
|
||||
``formfield_overrides`` is a dictionary mapping a field class to a dict of
|
||||
arguments to pass to the field at construction time.
|
||||
|
||||
Since that's a bit abstract, let's look at a concrete example. The most common
|
||||
use of ``formfield_overrides`` is to add a custom widget for a certain type of
|
||||
field. So, imagine we've written a ``RichTextEditorWidget`` that we'd like to
|
||||
use for large text fields instead of the default ``<textarea>``. Here's how we'd
|
||||
do that::
|
||||
|
||||
from django.db import models
|
||||
from django.contrib import admin
|
||||
|
||||
# Import our custom widget and our model from where they're defined
|
||||
from myapp.widgets import RichTextEditorWidget
|
||||
from myapp.models import MyModel
|
||||
|
||||
class MyModelAdmin(admin.ModelAdmin):
|
||||
formfield_overrides = {
|
||||
models.TextField: {'widget': RichTextEditorWidget},
|
||||
}
|
||||
|
||||
Note that the key in the dictionary is the actual field class, *not* a string.
|
||||
The value is another dictionary; these arguments will be passed to
|
||||
:meth:`~django.forms.Field.__init__`. See :ref:`ref-forms-api` for details.
|
||||
|
||||
.. warning::
|
||||
|
||||
If you want to use a custom widget with a relation field (i.e.
|
||||
:class:`~django.db.models.ForeignKey` or
|
||||
:class:`~django.db.models.ManyToManyField`), make sure you haven't included
|
||||
that field's name in ``raw_id_fields`` or ``radio_fields``.
|
||||
|
||||
``formfield_overrides`` won't let you change the widget on relation fields
|
||||
that have ``raw_id_fields`` or ``radio_fields`` set. That's because
|
||||
``raw_id_fields`` and ``radio_fields`` imply custom widgets of their own.

``formfield_for_foreignkey(self, db_field, request, **kwargs)``
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The ``formfield_for_foreignkey`` method on a ``ModelAdmin`` allows you to
|
||||
override the default formfield for a foreign key field. For example, to
|
||||
return a subset of objects for this foreign key field based on the user::
|
||||
|
||||
class MyModelAdmin(admin.ModelAdmin):
|
||||
def formfield_for_foreignkey(self, db_field, request, **kwargs):
|
||||
if db_field.name == "car":
|
||||
kwargs["queryset"] = Car.object.filter(owner=request.user)
|
||||
return db_field.formfield(**kwargs)
|
||||
return super(MyModelAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)
|
||||
|
||||
This uses the ``HttpRequest`` instance to filter the ``Car`` foreign key field
|
||||
to only the cars owned by the ``User`` instance.
