How does one handle non-changing existing data when updating a form?
My 'add' form includes several fields my 'edit' form does not. For
example once I create a contact and assign it a company_id foreign
key, it will never change. So when I implement my edit method in my
view, I get errors about not providing fields already set.
form = ContactForm( request.POST, instance=contact )
form.errors says I need to provide a company, but it is already saved
in the database.
What am I missing here?
If you're using forms.Form objects instead of forms.ModelForm objects
then that would explain it. If you're dealing with a model then you
should probably be using a ModelForm.
To have a ModelForm that doesn't show certain fields just add a Meta
section and set the field names in an iterable named 'exclude'.
