在DJANGO保存Formset

Question

我从模型中获得了一个表单集，但是当我试图保存多个格式化集时，我会得到以下错误：

KeyError at /auditoria/auditoria_tab/ 'id_control‘

我的看法是：

@staff_member_required
def AuditoriaView(request):
   class RequiredFormset(BaseFormSet):
      def __init__(self,*args,**kwargs):
         super(RequiredFormset,self).__init__(*args,**kwargs)
         for form in self.forms:
            form.empty_permitted =  False

   auditoriaFormset = formset_factory(AuditoriaForm,max_num=31,formset=RequiredFormset)

   if request.method == 'POST':
      usuario = request.user
      accion = 'Registro nuevo Detalle de Auditoria'
      formset  = auditoriaFormset(request.POST)
      for form in formset.forms:
         if formset.is_valid():
            obj = form.save(commit=False)
            #obj.id_control = control
            obj.auditor = request.user
            obj.save()
   else:
      formset = auditoriaFormset()

   return render_to_response('audit_auditoria.html',
                              {'formset':formset},
                              context_instance=RequestContext(request))

我的表格：

class AuditoriaForm(forms.ModelForm):
   id_control = forms.ModelChoiceField(queryset=Control.objects.all().order_by('nombre'),\
                                       required=True,label='Control', widget=forms.Select(attrs={'class':'form-control'}))
   id_analista = UserModelNameChoiceField(queryset=User.objects.filter(is_staff=False),\
                                          required = True, label='Analista', widget=forms.Select(attrs={'class':'form-control'}))
   fecha = forms.DateField(widget=DateInputCustom())
   id_tipoerror = forms.ModelChoiceField(queryset=TipoError.objects.all(),required=True, label='Tipo Falla', widget=forms.Select(attrs={'class':'form-control'}))
   id_sharepoint = forms.IntegerField(label='Sharepoint', widget=forms.NumberInput(attrs={'class':'form-control','style': 'width:80px'}))
   id_estado = forms.ModelChoiceField(queryset=Estado.objects.all(),required=True, label='Estado', widget=forms.Select(attrs={'class':'form-control'}))
   observaciones = forms.CharField(widget=forms.Textarea(attrs={'rows':5,'cols':30}))

   class Meta:
      model = DetalleAuditoria
      exclude = ('auditor',)

   def __init__(self,*args,**kwargs):
      super(AuditoriaForm,self).__init__(*args,**kwargs)
      self.helper = FormHelper(self)

   def clean(self):
      cleaned_data = super(AuditoriaForm,self).clean()
      idc = cleaned_data['id_control']
      fechac = cleaned_data['fecha']

      try:
         DetalleAuditoria.objects.get(id_control = idc,fecha = fechac )
         raise forms.ValidationError('Esta Incidencia ya ha sido registrada')
      except DetalleAuditoria.DoesNotExist:
         pass

      return cleaned_data

模板：

            <table class="table table-responsive table-condensed table-bordered">
              {{ formset.management_form }}

                  {{ form.id_control }}
                </th>

当我想保存数据时，如何使用来自其他窗体集中的第一个格式化集的字段ID_CONTROL。

我不知道我是否正确地使用了格式集？

任何建议

提前谢谢

更新:我得到了“干净”函数中的错误。当视图试图保存第二种格式集时，在下面的行中出现了以下错误：

  idc = cleaned_data['id_control']

在错误页面中，我可以看到post，我可以看到第一个格式集的id_control值，但是对于第二个格式集，我看到了除id_control以外的所有字段。

在我看来，以这种方式将相同的控制id放入下一种形式似乎是不明智的。无论如何，要解决您所要求的问题，这应该是有效的(具有不同的“what”值的表单)：

   id_control=None
   if request.method == 'POST':
      usuario = request.user
      accion = 'Registro nuevo Detalle de Auditoria'
      formset  = auditoriaFormset(request.POST)

      for counter, form in enumerate(formset.forms):
         if formset.is_valid():
            obj = form.save(commit=False)
            if counter>0:
                obj.id_control = id_control
            obj.auditor = request.user
            obj.save()
            if counter==0:
                id_control=obj.id_control
   else:
      formset = auditoriaFormset()
