Hei,
I hope someone could shed some light on this one.
I have these in their appropriate files:
class ShoppinglistForm(ModelForm):
def __init__(self, user=False, *args, **kwargs):
ModelForm.__init__(self, *args, **kwargs)
self.fields['pantry'].empty_label = None
if user:
self.fields['pantry'].queryset =
Product.objects.filter(owner=user)
class Meta:
model = Shoppinglist
def new(request):
if request.method == 'POST':
form = ShoppinglistForm(request.POST)
if form.is_valid():
try:
list = Shoppinglist(name=form.cleaned_data['name'],
pantry=form.cleaned_data['pantry'])
list.save()
return redirect('blackem.users.views.home')
except ObjectDoesNotExist:
return redirect('blackem.users.views.home')
else:
form = ShoppinglistForm(user = request.user)
return render_to_response('shoppinglists/shoppinglist_form.html',
{'form': form,
'logged': True},
context_instance=RequestContext(request))
After pressing Submit on the form, I get this:
Traceback:

Exception Type: TypeError at /shoppinglists/new
Exception Value: int() argument must be a string or a number, not
'QueryDict'
Taking away the 'user' keyword argument makes it work nicely. But I
need to include only the user's pantries in the choices of the select
wiget.
