python - Django Form Clean Method Test Error -

i'm testing form wrote earlier. reason, test won't pass. it's form ignoring data pass it, , don't see why. traceback tells me user variable in clean method of form none, though user passed form. traceback:

... in clean if user.pk not userwebsite.user.pk: attributeerror: 'nonetype' object has no attribute 'pk'

the form:

class createauditform(forms.form):     user = forms.modelchoicefield(queryset=user.objects.all(), widget=hiddeninput)     website = forms.modelchoicefield(queryset=userwebsite.objects.all(), widget=hiddeninput)     emails = forms.charfield(         max_length=250,         required=false     )      def clean_user(self):         user = self.cleaned_data.get('user', none)         if not user.groups.filter(name__iexact='subscribed').exists() , not user.groups.filter(name__iexact='addon').exists():             raise forms.validationerror(_("you must have active subscription request \ website audits. please try again after subscribing us."))         return user      def clean(self):         data = self.cleaned_data         user = data.get('user')         userwebsite = data.get('website', none)          if userwebsite.user:             if user.pk not userwebsite.user.pk:                 raise forms.validationerror(_("sorry, try again."))         elif userwebsite.addon:             if user.pk not userwebsite.addon.pk:                 raise forms.validationerror(_("sorry, try again."))         return self.cleaned_data      def save(self):         # action 

the test:

class createauditformtestcase(testcase):      def setup(self):         super(createauditformtestcase, self).setup()         self.form = createauditform         ...         self.website = website.objects.create(             title="permanence",             url="https://www.badabuyhere.com",             display="www.bababuyhere.com")         self.unsubscriber = user.objects.create(             username="adiagojesse",             first_name="adiago",             last_name="jesse",             email="bannerfare@coldmount.com",             password="tigermountainvalley"         )         self.unsubscriberwebsite = userwebsite.objects.create(             user=self.unsubscriber,             website=self.website,             is_competitor=false         )      ...     def test_user_validation(self):         data = {             "user":self.unsubscriber.pk,             "website":self.unsubscriberwebsite.pk,             "emails":"john@gmail.com, jeff@gmail.com"         }         self.asserttrue(self.unsubscriber)         self.asserttrue(self.unsubscriberwebsite)         audit = self.form(data)         self.assertequal(audit.is_valid(), false) 

this simple issue can't pick on, what's frustrating me, lol. appreciated.

my guess in createauditform.clean, useris none because clean_user raised validationerror. validationerror comes fact user not have groups needs.

another issue see test equality between model instances in django, should not use primary keys test using instances directly, using == , not is. (see https://stackoverflow.com/a/13650309/1644198 more information on is , ==)

example:

if user != userwebsite.user:     # etc...
