#27231: Initialize forms in ModelAdmin like View (i.e. add get_form_kwargs to
contrib.admin)

There's no way to control initialization of a form instance with
ModelAdmin like you can with, say, a View, by providing an override for
get_form_kwargs. This is something I need to do.
Is there a architectural reason why ModelAdmin doesn't have
get_form_kwargs? Or if I provided a PR, would that be welcome?
The closest ticket I can find related to this is #10305.
This is kind of how I'm working around it for now... to get one particular
kind of value into my form constructor call, I'm kind of "injecting" it
in:
{{{
class MyModelAdmin(ModelAdmin):
model = MyModel
form = MyForm
def get_form(self, request, obj=None, **kwargs):
form_class = super(MyModelAdmin, self).get_form(request, obj=obj,
**kwargs)
some_parameter_for_one_thing =
self.get_some_parameter_for_one_thing()
from django.forms.models import ModelFormMetaclass
class FormMetaclass(ModelFormMetaclass):
def __new__(mcs, name, bases, attrs):
attrs["some_parameter_for_one_thing"] =
some_parameter_for_one_thing
return super(FormMetaclass, mcs).__new__(mcs, name, bases,
attrs)
another_parameter_for_another_thing=
obj.another_parameter_for_another_thing
import six
class FormWrapper(six.with_metaclass(FormMetaclass, form_class)):
def __init__(self, *args, **kwargs):
data = {"another_parameter_for_another_thing":
six.text_type(another_parameter_for_another_thing)}
super(FormWrapper, self).__init__(data, *args, **kwargs)
return FormWrapper
}}}
