Django的：类视缺乏属性COOKIES

Question

我目前正在与REST和Backbone.js的玩弄，跑进这个问题：

'LoginView' object has no attribute 'COOKIES' 

这里说到下面的代码可能造成的问题。我已经在javascript中注释了一些东西，因为我希望它直接加载到服务器上，但我认为它将同样好。

我还可以补充一点，我检查了表单中的csrf-token并且它在那里。

views.py

class LoginView(TemplateView): 
    authentication_form=LoginForm 
    form_class = LoginForm 
    redirect_field_name=REDIRECT_FIELD_NAME 
    template_name = 'front/login.html' 
    initial = {'key': 'value'} 

    def get(self, request, *args, **kwargs): 
     form = self.form_class(initial=self.initial) 
     return render(request, self.template_name, {'form': form}) 

    @method_decorator(sensitive_post_parameters()) 
    @csrf_protect 
    @never_cache 
    @api_view(['GET', 'POST']) 
    def post(self, request, *args, **kwargs): 
     form = self.form_class(request.POST) 
     print request.COOKIES('csrftoken') 
     print request.POST.get('csrfmiddlewaretoken') 
     if form.is_valid(): 
      #if not is_safe_url(url=redirect_to, host=request.get_host()): 
      # redirect_to = resolve_url(settings.LOGIN_REDIRECT_URL) 
      print request.POST.get('email') 
      #user = self.get_user(request.POST.get('email')) 
      #print user 
      #auth = UserDataAuthentication(request, user) 
      user = authenticate(email=request.POST.get('email'), password=request.POST.get('password')) 
      if user is not None: 
       auth_login(request, user) 
       return Response(user, status=status.HTTP_201_CREATED) 
     return HttpResponseRedirect('/login/') 

login.js

var csrftoken = $('meta[name="csrf-token"]').attr('content'); 
SigninView = Backbone.View.extend({ 
    events: { 
     //"click button[type=submit]": "sendRequest" 
    }, 
    sendRequest: function(event){ 
     //event.preventDefault(); 
     var csrftoken = $.cookie('csrftoken'); 
     var url = '/login/validate/'; 
     var email = $("#id_email").val(); 
     var password = $("#id_password").val(); 
     var items = { 
         email: email, 
         password: password, 
         csrfmiddlewaretoken: csrftoken 
        };  
     console.log(csrftoken); 
     $.ajax({ 
      url:url, 
      type:'POST', 
      dataType:"json", 
      data: items, 
      success: function (data) { 
       var json = $.parseJSON(data); 
       console.log(data); 
      }, 
      error: function (xhr, textStatus, error) { 
       $("#form_error").css('padding','7px').css('border-radius','4px').html('Error recieved: ' + error).fadeIn(); 
       console.log("Status: "+textStatus); 
       console.log("Type: "+error); 
      } 
     }); 
    } 
}); 
var signin_view = new SigninView({ 
    el: $("#login_form") 
}); 

我们两个人这方面的工作，我已在自己与Python工作，而我的朋友采取JS的护理-部分。我还没有经历足够的Django来实际发现可能由于cookie而导致错误的原因。如果可以的话，我会尝试在大多数情况下远离cookie，但这似乎很困难。

，当然还有：回溯：

您使用的一个方法的功能装饰。

这不起作用：装饰器返回的函数期望其第一个参数是request，并且接收self。

用途：

method_decorator(csrf_protect) 
# and so on
