django - Django Model Form Error on instance with model

Question

Trying to instance a model form in django, I am passing in an instance and I get validation errors out, despite the data being entered from the very same form minutes prior. ignore the extra fields stuff I have tried removing it and the issue persists. It adds extra fields from a separate key value table.

Django Version 1.3

def edit(request,company_uuid,contact_uuid,address_uuid):
    mcompany = get_object_or_404(models.Company, uuid = company_uuid)
    extra_questions, extra_ids = get_questions(request, 2)
    if request.method == 'POST': # If the form has been submitted...
        form = forms.EditCompanyForm(request.POST,instance=mcompany, extra=extra_questions, extra_ids=extra_ids)
        if form.is_valid():
            fModel = form.save(commit = False)
            for (question, answer) in form.extra_answers():
                save_answer(request, question, answer, mcompany.uuid, 2)
            form.save()    
            url = reverse('contacts_details',kwargs={'company_uuid':mcompany.uuid,
                                                                   'address_uuid':address_uuid,
                                                                   'contact_uuid':contact_uuid})
            return HttpResponseRedirect(url)
    else:
        form = forms.EditCompanyForm(request.POST,instance=mcompany, extra=extra_questions, extra_ids=extra_ids)
    return share.output_page(request,'contacts/edit.html',{'form': form,
                                                            'company_uuid':mcompany.uuid,
                                                            'address_uuid':address_uuid,
                                                            'contact_uuid':contact_uuid})

Answer 1

You're passing in request.POST even in the GET stage of the view (after the else), when the POST dictionary will be empty, so naturally there will be validation errors.
