Django form checkbox to change a value in UserProfile - django

Question

I'm using Django-Profiles with Django 1.4, and I need a way to unsubscribe a user, so they can stop getting emails.
One of the fields in my UserProfile model is user_type, and I have a USER_TYPES list of choices. To keep users in the system, even if they unsubscribe, I decided to have one of the USER_TYPES be InactiveClient, and I'd include a checkbox like so:
Models.py:
USER_TYPES = (
('Editor', 'Editor'),
('Reporter', 'Reporter'),
('Client', 'Client'),
('InactiveClient', 'InactiveClient'),
('InactiveReporter', 'InactiveReporter'),
)
class UserProfile(models.Model):
user = models.OneToOneField(User, unique=True)
user_type = models.CharField(max_length=25, choices=USER_TYPES, default='Client')
... etc.
forms.py
class UnsubscribeForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(UnsubscribeForm, self).__init__(*args, **kwargs)
try:
self.initial['email'] = self.instance.user.email
self.initial['first_name'] = self.instance.user.first_name
self.initial['last_name'] = self.instance.user.last_name
except User.DoesNotExist:
pass
email = forms.EmailField(label='Primary Email')
first_name = forms.CharField(label='Editor first name')
last_name = forms.CharField(label='Editor last name')
unsubscribe = forms.BooleanField(label='Unsubscribe from NNS Emails')
class Meta:
model = UserProfile
fields = ['first_name','last_name','email','unsubscribe']
def save(self, *args, **kwargs):
u = self.instance.user
u.email = self.cleaned_data['email']
u.first_name = self.cleaned_data['first_name']
u.last_name = self.cleaned_data['last_name']
if self.unsubscribe:
u.get_profile().user_type = 'InactiveClient'
u.save()
client = super(UnsubscribeForm, self).save(*args,**kwargs)
return client
Edit: I've added additional code context. if self.unsubscribe: is in save() override. Should that be somewhere else? Thank you.
Edit2: I've tried changing UnsubscribeForm in several ways. Now I get a 404, No User matches the given query. But the view function being called works for other forms, so I'm not sure why?
urls.py
urlpatterns = patterns('',
url('^client/edit', 'profiles.views.edit_profile',
{
'form_class': ClientForm,
'success_url': '/profiles/client/edit/',
},
name='edit_client_profile'),
url('^unsubscribe', 'profiles.views.edit_profile',
{
'form_class': UnsubscribeForm,
'success_url': '/profiles/client/edit/',
},
name='unsubscribe'),
)
These two urls are calling the same view, just using a different form_class.
Edit3: So I don't know why, but when I removed the trailing slash from the unsubscribe url, the form finally loads. But when I submit the form, I still get an error: 'UnsubscribeForm' object has no attribute 'unsubscribe' If anyone could help me understand why a trailing slash would cause the 404 error (No User matches the given query) I wouldn't mind knowing. But as of now, the form loads, but doesn't submit, and the trace ends on this line of my form:
if self.unsubscribe:

Answering my own question again. On ModelForms, you can add form elements that don't exist in the model, and access the value of those fields by accessing self.cleaned_data['form_element_name'] in the save method.
This is what my save method looks like:
def save(self, *args, **kwargs):
u = self.instance.user
p = self.instance.user.get_profile()
u.email = self.cleaned_data['email']
u.first_name = self.cleaned_data['first_name']
u.last_name = self.cleaned_data['last_name']
if self.cleaned_data['unsubscribe']:
p.user_type = 'InactiveClient'
u.save()
p.save()
client = super(UnsubscribeForm, self).save(*args,**kwargs)
return client
