I'm using formsets fairly successfully (thanks very much to Malcolm's
great quiz example), but it seems to me there is some functionality
missing. Say I create a formset of BookForms, where BookForm is a
ModelForm. The user will filleout the formset and for each form in
the formset, when I receive the POST data I will create an instance of
a Book based on that data.
I can't use a modelform_factory because when I create the formset, I
don't have any book objects yet (which I would need to set the
queryset for the modelform_factory). So instead I use a
formset_factory that references a BookForm that is derived from a
ModelForm. However, when I use a formset_factory, I don't have a nice
way to save the forms in my formset as new book objects. For example,
when I use just a ModelForm, I can do
bookForm = BookForm(postDict)
newBookObj = bookForm.save()
When I use the formset, I can loop through the forms in the formset,
but then I think I have to create the book objects myself.
for form in bookFormSet.forms:
newBookObj = Book(title=form.cleaned_data['title'])
If I add fields to my book model, I would have to now rememeber to
copy them inside this loop.
Have I missed something?
