Django - 在表单__init__中调用super,在"GET"上启动表单验证

Question

我在我的应用程序中有一个ModelForm,我想在其中修改init函数以添加一些自定义.

当init被注释掉时,表单可以正常工作和验证.当我覆盖init并转到表单呈现的url时,它会自动显示"Field xyz is required"

这个问题的原因是什么？

class CreateListView(FormMixin, ListView):

    def get_context_data(self, **kwargs):
        self.object_list = self.get_queryset()
        data = super(ListView, self).get_context_data()
        data['object_list'] = self.get_queryset()
        data['form'] = self.get_form(self.form_class)
        return data

    def post(self, request, *args, **kwargs):
        form = self.form_class(request.POST)
        if form.is_valid():
            form = form.save()
            return HttpResponseRedirect(form.get_absolute_url())
        return self.form_invalid(self.get_context_data())



class ActionGroupForm(forms.ModelForm):

    class Meta:
        model = ActionGroup

    def __init__(self, *args, **kwargs):
        super(ActionGroupForm, self).__init__(args, kwargs)

你错过了*,**:

super(ActionGroupForm, self).__init__(*args, **kwargs)
