Django模型表單錯誤實例模型

Question

試圖在django中實例化一個模型表單，我傳入一個實例並得到驗證錯誤，儘管數據是從前幾分鐘輸入的。忽略額外的字段，我試圖刪除它，問題依然存在。它從單獨的鍵值表中添加額外的字段。

的Django 1.3版

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})

你傳遞request.POST即使在視圖（else)後，當POST字典將是空的GET階段，所以自然會出現驗證錯誤
