I am trying to filter a field on a ModelForm. I am subclassing the generic CreateView for my view.
I found many references to my problem on the web, but the solutions do not seem to work (for me at least) with Django 1.3's class-based views.
Specifically, my users need to add Subscribers, and each Subscriber has a m2m field that assigns him/her to a SubscriberList. When the form to create a subscriber loads for a given user, I need to options in subscriber_list to be filtered for that user's lists only.
Here are my models:
#models.py
class Subscriber(models.Model):
user = models.ForeignKey(User)
subscriber_list = models.ManyToManyField('SubscriberList')
....
class SubscriberList(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=70)
....
Here is my view:
#views.py
class SubscriberCreateView(AuthCreateView):
model = Subscriber
template_name = "forms/app.html"
form_class = SubscriberForm
success_url = "/app/subscribers/"
def form_valid(self, form):
self.object = form.save(commit=False)
self.object.user = self.request.user
return super(SubscriberCreateView, self).form_valid(form)
Here is my original form for adding a Subscriber, with no filter:
#forms.py
class SubscriberForm(ModelForm):
class Meta:
model = Subscriber
exclude = ('user', 'facebook_id', 'twitter_id')
Here is my modified form, attempting to filter, but doesn't work:
#forms.py
class SubscriberForm(ModelForm):
class Meta:
model = Subscriber
exclude = ('user', 'facebook_id', 'twitter_id')
def __init__(self, user, **kwargs):
super(SubscriberForm, self).__init__(**kwargs)
self.fields['subscriber_list'].queryset = SubscriberList.objects.filter(user=user)
If I change this modified form as so:
def __init__(self, user=None, **kwargs)
It works - It brings me NO subscriber lists. But any way I try to pass the request user, for eg., def __init__(self, user=request.user, **kwargs), I invariably get a a name "request" or name "self" not defined error.
So, how can I modify my code to filter subscriber_list by the request.user, and still use Django 1.3's CreateView.
