Re: dynamically filling ChoiceField
Here is how you can modify the form at runtime. You can write
a constructor. In this example, I need the request for validation.
{{{
class TestForm(forms.ModelForm):
class Meta:
model=Filter_Test
def __init__(self, request, *args, **kwargs):
super(TestForm, self).__init__(*args, **kwargs)
self.request=request
...
}}}
You can set choices for fields after the super call. Example:
self.fields['myfield'].choices=choices

Re: dynamically filling ChoiceField
Some more details would be good, but off the top of my head, something like this might work: def my_view(request): form = MyForm() form.fields['mychoice'].choices = ((1,'ABC'),(2,'XYZ')) I havent' been able to test this out, so make sure you do before you using it. You can of-course do any amount of pre-processing before you apply that tuple.

dynamically filling ChoiceField
I've been tearing out what little hair I have left trying to figure this out. How do I dynamically fill a ChoiceField by filtering on a value known to the URLView? Every "dynamic fill" example I've found assumes the form knows it all - I haven't seen anything which shows me how to pass that value from the view to the form. Help? Please?
