Django 1.9类型错误__init __（）需要1个位置参数，但有2个给出 - 类装饰问题

Question

上下文的一点：我试图创建一个CreateView页面供用户输入信息，同时使用Django 1.9网址'/ profile /'。

当用户未登录时，我转到/ profile/url，然后它会按预期将我重定向到登录页面。然而，当我登录到网站，然后去/型材/那么它会显示此错误：

TypeError at /profile/

__ init __() takes 1 positional argument but 2 were given

目前，我正在装饰用method_decorator类，如提及docs here：https://docs.djangoproject.com/en/1.10/topics/class-based-views/intro/#decorating-the-class。

这是我views.py：

@login_required(login_url = "/login/", redirect_field_name = None) 
    @method_decorator(login_required, name = 'dispatch') 
    class SpkCreateView(CreateView): 
     form_class = SpkCreateForm 
     template_name = 'userprofile/spk_form.html' 
     def get(self, request): 
      form = self.form_class(None) 
      return render(request, self.template_name, {'form': form}) 
     def post(self, request): 
      form = self.form_class(request.POST) 
      if form.is_valid(): 
       spk_fname = form.cleaned_data['spk_fname'] 
       spk_lname = form.cleaned_data['spk_lname'] 

为method_decorator“名字”的说法也被绊倒我，所以我不知道它是否是做些什么。

如果有人有任何解决方案，那么谢谢！

编辑：

改变@login_required(login_url = "/login/", redirect_field_name = None) @method_decorator(login_required, name = 'dispatch')

到@method_decorator(login_required(login_url = "/login/", redirect_field_name = None), name = 'dispatch')

，这是从Powershell的

你跟login_required既没有@method_decorator装饰类的回溯。您需要将您要使用到method_decorator装饰，在这种情况下：

@method_decorator(login_required(login_url="/login/", redirect_field_name=None), name='dispatch') 
class SpkCreateView(CreateView): 
    ...
