Description (last modified by )
The Django ModelAdmin
does not seem to provide a get_form_kwargs
, it however has a get_formset_kwargs
. The get_form
also does not seem to create a form instance, but return a form class: the result of logic that works with the formset_factory
.
In understand that renaming get_form
to get_formclass
will likely break a lot, so that is not an option, but we can define a get_form_kwargs
which does not exists up till now, and then use this to generate optionally extra kwargs that are then injected when we *use* the form, so something like:
ModelForm = self.get_form( request, obj, change=not add, fields=flatten_fieldsets(fieldsets) ) # ... form = ModelForm(request.POST, request.FILES, instance=obj, **self.get_form_kwargs(request))
in the _chageform_view
for example. This makes it easy to inject for example the logged in user into the form, which is often done to limit the form fields.
An alternative for that scenario could be to override formfield_for_dbfield
, etc. but the problem with these functions is that the scope is limited to a single form field, so it does not really is flexible to do something at the level of the form.
