Hi list,
sorry for bugging you again but I cannot solve this problem.
In my applications I have a model DVD and a model Genre
related via a ManyToMany field. The problem is that the
edit form doesn't show the selected genres already assigned
to a DVD instance.
The form looks like:
class DVDForm(forms.Form):
...
genres =
forms.ModelMultipleChoiceField(queryset=Genre.objects.order_by('name'))
And the view function like this:
def dvd_edit(request, slug):
dvd = get_object_or_404(DVD, slug=slug)
if request.method == 'POST':
form = forms.DVDForm(request.POST)
if form.is_valid():
for field in ['title', 'release_year', 'case_type']:
setattr(dvd, field, form.cleaned_data[field])
dvd.save()
return HttpResponseRedirect('/')
else:
form = forms.DVDForm(dvd.__dict__)
# False
print form.is_valid()
return render_to_response('dvd_edit.html', \
{'form': form, 'original': dvd},
context_instance=RequestContext(request))
Help is greatly appreciated.
Thanks for your time,
Kai
