我目前正在使用REST和backbone.js，遇到了这个问题：

'LoginView' object has no attribute 'COOKIES'

下面的代码可能导致了这个问题。我已经在javascript中注解掉了一些东西，因为我想把它直接加载到服务器上，但是我认为把它带沿着也一样好。
我还可以补充说，我已经检查了表单中的csrf-token，它就在那里。
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")
});

我们是两个人在做这个，我自己负责Python，而我的朋友负责js部分。我还没有足够的Django经验来发现是什么导致了cookie的错误。如果可以的话，我大多数时候都试着远离cookie，但是在这里似乎很难。
当然还有：回溯：
