When I try to add new Attendee with a class based view I get the error
matriculation_attendee.event_id may not be NULL with this code:
class Event(models.Model):
""" Model representing an event """
place = models.ForeignKey(Place, blank=True, null=True)
slug = AutoSlugField(populate_from=('company', 'name'))

# Call the base implementation first to get a context

self).get_context_data(**kwargs)
context['event'] = event
return context
def get_form_kwargs(self, **kwargs):
context = self.get_context_data()
kwargs = super(EventContextMixIn,
self).get_form_kwargs(**kwargs)
kwargs['initial']['event'] = context['event']
return kwargs
class EventCreateView(EventContextMixIn, CreateView):
pass
class EventUpdateView(EventContextMixIn, UpdateView):
pass
class EventListView(EventContextMixIn, ListView):
context_object_name = "model_list"
class EventDetailView(EventContextMixIn, DetailView):
context_object_name = 'model'
url(r'^events/(?P<event_id>[-\w]+)/attendees/add/$',
EventCreateView.as_view(form_class=AttendeeForm,
template_name='matriculation/attendee_update.html'),
name='matriculation_attendees_add'),
Am I using this wrong? I'm basically trying to set this up so I the
url defines the event and then I can create models for the specific
event.
