我在一个模板中有两个表单:UserEditFormUserRoleForm。如您所见,UserRoleForm是一个自定义表单。如何在基于类的视图中通过post方法保存表单数据? get方法工作正常,但我不能通过post方法保存数据。下一个代码引发错误,您可以在下面看到。在我看来,我试图在post方法中错误地保存表单。我的错误在哪里?

forms.py:

class UserEditForm(UserChangeForm):
    class Meta:
        model = User
        exclude = ('groups', 'is_superuser', 'is_staff', 'user_permissions',)

class UserRoleForm(forms.Form):
    CHOICES = ((0, _('Admin')), (1, _('Moderator')), (2, _('Simple User')))
    user_role = forms.ChoiceField(widget=forms.RadioSelect, choices=CHOICES)

    def __init__(self, *args, **kwargs):
        super(UserRoleForm, self).__init__(*args, **kwargs)
        self.fields['user_role'].widget.attrs = {
            'id': 'user_role',
        }

view.py:

class UserEditView(UpdateView):
    template_name = 'users/edit_user.html'
    form_class = UserEditForm
    second_form_class = UserRoleForm
    model = User

def post(self, request, *args, **kwargs):
    form = self.form_class(self.request.POST)
    second_form = self.second_form_class(self.request.POST)
    if form.is_valid() and second_form.is_valid():
        new_user = second_form.save(commit=False)
        user_role = second_form.cleaned_data['user_role']
        if user_role==0:
            new_user.is_superuser=True
        elif user_role==1:
            new_user.is_staff=True
        elif user_role==2:
            new_user.is_superuser=False
            new_user.is_staff=False
        new_member.save()
        form.save()
        data = dict()
        data['form_is_valid'] = True
        context = {'users': User.objects.order_by('username')}
        data['html_users'] = render_to_string('users/users.html', context)
    else:
        data = dict()
        data['form_is_valid'] = False
        data['form_errors'] = form.errors
    return JsonResponse(data)

错误:
