python - Updateview with dynamic form_class -


i dynamically change form_class of updateview cbv in django 1.6.

i've tried using get_context_data(), didn't since form initialized. need happen during __init__, guess. here's i've tried on __init__:

class updatepersonview(generic.updateview):      model = person     form_class = ""      def __init__(self, *args, **kwargs):         super(updatepersonview, self).__init__(*args, **kwargs)         person = person.objects.get(id=self.get_object().id)         if not person.somefield:             self.form_class = oneformclass         elif person.somefield:             self.form_class = someotherformclass

i'm stuck 'updatepersonview' object has no attribute 'kwargs' error message when executing person = person.objects.get(id=self.get_object().id).

when manually specifying id (e.g. id=9), setup works.

how can args/kwargs inside init method i'm overriding? particularly need access pk.

you should override get_form_class.

(also i'm not sure why you're querying person: object same self.get_object() already, there's no point getting id of querying again.)

def get_form_class(self):     if self.object.somefield:         return oneformclass     else:         return someotherformclass
