Sorry Alex, I should have been more clear, I need to access the fields of another model. I went ahead and did what you said to try and get it working, and I was able to get the fields from the form's model, but I get an error when trying to assign them to the choices property of my field.
The following code gives the following error: class ShelfAdmin(admin.ModelAdmin): sort_by = forms.ChoiceField(choices = ()) def __init__(self, *args, **kwargs): super(ShelfAdmin, self).__init__(*args, **kwargs) sort_by_choices = [('', '-------')] for field in self.model._meta.fields: sort_by_choices.append((field.name, field.verbose_name.title())) self.fields['sort_by'].choices = sort_by_choices admin.site.register(Shelf, ShelfAdmin) TypeError at /admin/shelf/shelf/add/ 'NoneType' object is unsubscriptable Which I guess means that self.fields is None. Any idea why this might be happening?
