Ok, [7847] is a good commit for make able to metaclass subclassing. This is the scenary: {{{ #!python #### model class FooModel(models.Model): name = models.CharField(max_length=100) #### forms class GenericForm(forms.Form): extra_field = forms.CharField() class FooForm(GenericForm, forms.ModelForm): # to avoid python metaclass conflict error: __metaclass__ = type('FooFormMetaclass', (GenericForm.__metaclass__, forms.ModelForm.__metaclass__), {}) non_existing_field = forms.CharField() class Meta: model = FooModel }}} In previous scenario, {{{FooForm}}} should contain both {{{name}}}, {{{extra_field}}} and {{{nonexisting_field}}}. But only appears {{{name}}} field in {{{base_fields}}}. See this test: {{{ #!python >>> from testapp.forms import FooForm >>> FooForm.base_fields.keys() ['name'] }}} I will attach a patch thats fixes problem.",Bug,closed,Forms,dev,Normal,fixed,,,Accepted,1,0,0,1,0,0
