Question

当我将request.POST参数传递给我的CargoUnitFormSet时。它在命令行中出现此错误。

File "C:\Python27\lib\site-packages\django\utils\functional.py", line 35, in __get__
res = instance.__dict__[self.name] = self.func(instance)
File "C:\Python27\lib\site-packages\django\forms\formsets.py", line 98, in management_form
code='missing_management_form',
ValidationError: [u'ManagementForm data is missing or has been tampered with']

在myform中我创建了一个formset。我的formset显示在我的网页上。每当我传递request.POST作为参数来保存我的formset时，它都会给出此验证错误。这是我的视图功能：

def create_entity(request):
    from django.forms import BaseFormSet
    from django.forms import formset_factory
    from django.forms.models import modelformset_factory, BaseModelFormSet

    CargoUnitFormSet = formset_factory(CargoUnitForm,max_num=3)
    data = dict()

    if request.method == 'POST':
        cargo_form = CargoForm(request.POST, request.FILES or None)
        cargo_unit_formset = CargoUnitFormSet(request.POST,prefix="foo")
        if not cargo_form.is_valid():
            data['form_is_valid'] = False

    if cargo_form.is_valid() and cargo_unit_formset.is_valid():
        cargo = cargo_form.save()
        for form in cargo_unit_formset.forms:
            cargo_unit = form.save(commit=False)
            cargo_unit.list = cargo
            cargo_unit.save()
            data['form_is_valid'] = True

    context = {
       'form': cargo_form,
       'formset':cargo_unit_formset
     }


    data['html_form'] = render_to_string("cargos/form-create.html", context, request=request)
     return JsonResponse(data)

这是我用于formset的相关html模板

<div class="row">
    {{formset.management_formset}}

    {% for form in formset.forms %}
      <div class="item well">
        {{ form.as_p }}
        <p><a class="delete btn btn-danger" href="#"><i class="icon-trash icon-white"></i> Delete</a></p>
      </div>
    {% endfor %}
  </div>

提前致谢。
