Project description

Author: Keryn Knight
Version: 0.1.1

fakeinline provides enough of the methods and attributes to trick the Django Admin into displaying it when mounted as part of an inlines declaration on a ModelAdmin. Where possible it does so without subclassing real Django classes, as should be the case with Duck Typing.

The 2 necessary subclasses are the FakeInline class itself, which must subclass InlineModelAdmin, and the model attribute, FakeModel which must subclass Model, but is unmanaged and abstract, so there is nothing touching the database.

Why?!

The most interesting thing about the Django Admin is trying to bend it to my will. This is an example of my winning.

No really, why?

Because it’s actually nicer to be able to wedge additional things into the admin, without overriding the change_form.html template on a per-model, per-app basis.

Example usage

Here’s a simple way of putting the classic words Hello world onto a ModelAdmin:

class MyFormset(FakeFormset):
    # this probably works, but usually you'd point it at a template file.
    template = Template('{{inline_admin_formset.formset.get_data}}')

    def get_data(self, *a, **kw):
        return 'Hello world'

class MyInline(FakeInline):
    formset = MyFormSet

class MyAdmin(ModelAdmin):
    inlines = [MyInline]

Whilst a silly example, it demonstrates how one might encapsulate display data (charts, change history, etc) in a re-usable(ish) component for display on the change view.

Tests

There’s a couple in fakeinline.tests … just enough to verify it doesn’t raise an exception on GET or POST.

The license

It’s the FreeBSD. There’s should be a LICENSE file in the root of the repository, and in any archives.
