Not sure how well known this is but I thought I'd share seeing as how
it cost me a lot of time and I can't find any discussion of it:
I have a form for a model. The model has three fields, but I only want
one displayed in the form. So I do this:
class NoteForm(ModelForm):
class Meta:
model = Note
fields = ('text')
Looks good, but craps out with: 'Caught an exception while rendering:
'NoneType' object has no attribute 'label''.
I checked the ModelForms documentation and they have this example when
discussing field exclusion:
class PartialAuthorForm(ModelForm):
class Meta:
model = Author
exclude = ('birth_date',)
Notice the comma after 'birth_date'? That was it. Hope this helps
someone.
