What is the best way to add data to a Django form?

Question

Django

There is a model:

class A(Model):
    name=CharField()
    user = ForeignKey(User)

The form:

Class FA(ModelForm):
    model=A
   fields = ['name']

What is the best way to append to the current user's form data without completely overriding form save with cbv? Those. before calling form_valid, you need to add information about the current user to the form. How and where?

class AUpdateView(LoginRequiredUpdateView):
    model = A
    form = FA
    success_url = '/'

Answer 1

class AUpdateView(LoginRequiredUpdateView):
    def get_form_kwargs(self):
        kwargs = super(AUpdateView, self).get_form_kwargs()
        kwargs['data'].update({'user': self.request.user})
        return kwargs
