Using a mixin with a Django form class

Question

I\'m thinking about creating a mixin form class so that I can add a common set of fields to a variety of otherwise very different forms. Just using it as a base class won\'t

Answer 1

Just providing some clarity on @Adam Dobrawy's answer, which helped me:

This doesn't work:

class NoteFormMixin(object):
    note = forms.CharField()

This does:

class NoteFormMixin(object):
    def __init__(self, *args, **kwargs):
        super(NoteFormMixin, self).__init__(*args, **kwargs)
        self.fields['note'] = forms.CharField()

This behaviour is probably related to how django collects fields during class instantiation or something.. I haven't bothered to get into weeds of it. I just found this tidbit lets me write my mixin in nice readable way, without any extra django-form-specific crud.
