Question

我想在同一屏幕上创建listview和createview，但是我不理解当前错误“'group_list'对象没有属性'object'”的含义。

我试图在createview的基础上创建它，但是列表很混乱。我还尝试创建和继承createview和listview类，但是发生了相同的错误。

#error
'group_list' object has no attribute 'object'

#forms
class GroupRequestForm(mixins.BaseModelForm):
    class Meta:
        model = belong
        fields = ('group',)

#view

class group_list(ListView,ModelFormMixin):
  model = group
  form_class = GroupRequestForm
  template_name = 'group/group_list.html'
  context_object_name = 'group_list'
  queryset = group.objects.all()

  def get(self, request, *args, **kwargs):
        self.object = None
        return super().get(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        self.object = None
        self.object_list = self.get_queryset()
        form = self.get_form()
        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(form)

# class group_list(CreateView,):
#   form_class = GroupRequestForm
#   template_name = 'group/group_list.html'
#   success_url = reverse_lazy('group:group_list')
#
#   def get_context_data(self, *, object_list=None, **kwargs):
#     context_data = super(group_list, self).get_context_data(**kwargs)
#     context_data['group_list'] = group.objects.all()
#     return context_data
#
#   def form_valid(self,form):
#     user = self.request.user
#     # POST.get('user_id')
#     form.instance.user = user
#     return super().form_valid(form)

# class group_list(ListView):
#   model = group
#   context_object_name = 'group_list'



# class group_request(CreateView):
#   model = models.belong
#   form_class = GroupRequestForm
#   emplate_name = 'group/group_list.html'
#   success_url = reverse_lazy('group:group_list')
#
#   def post(self, request, *args, **kwargs):
#     self.object = self.get_object()  # assign the object to the view
#     form = self.get_form()
#     if form.is_valid():
#       email = form.cleaned_data.get("email")
#       return self.form_valid(form)
#     else:
#       return self.form_invalid(form)
#
# class GroupListRequest(group_list,group_request):
#   def get(self, request, *args, **kwargs):
#
#     formView = group_request.get(self, request, *args, **kwargs)
#     listView = group_list.get(self, request, *args, **kwargs)
#     formData = formView.context_data['form']
#     listData = listView.context_data['group_list']
#     context = {'form': formData, 'group_list': listData}
#     return render(request, 'group/group_list.html', context)

我想在同一屏幕上创建listview和createview。

我所指的网站的一部分是错误的，而我更正后该错误消失了。非常感谢。

“ group_list”对象没有属性“ object”是什么意思？
