Django：錯誤：[u'ManagementForm數據丟失或已被篡改']在保存formset後

Question

當我按下提交按鈕保存的formset後，出現此錯誤： 「[u'ManagementForm data is丟失或已被篡改']」

這是我views.py

MarcheFormSet = formset_factory(PrixMarcheForm1, extra=2) 
if request.method == "POST": 
    formset = MarcheFormSet(request.POST) 
    if (formset.is_valid()): 
     for form in formset: 
      print form 
      form.save() 
      return redirect("/appartement/ajouter3/") 
    else: 
     print "nope" 

和我form.html代碼（模板由views.py調用）

{% if formset %} 
     <form action="" method='POST'>{% csrf_token %} 
      {{ formset.management_form }} 
      {% for form in formset %} 
       {{ form|crispy }} 
      {% endfor %} 
     <input type='submit' class='btn btn-default' value={{ outcome }}> 
     </form> 
    {% endif %} 

和想法s將不勝感激

您是否嘗試搜索您的問題？一個簡單的谷歌搜索ManagementForm data is missing or has been tampered with產量：

• Django 'ManagementForm data is missing or has been tampered with' when saving modelForms with foreign key link

• ManagementForm data missing error while formset validation

• Django Formset management-form validation error

• ManagementForm data missing error while formset validation

等等。
