Django的：類視缺乏屬性COOKIES

Question

我目前正在與REST和Backbone.js的玩弄，跑進這個問題：

'LoginView' object has no attribute 'COOKIES' 

這裏說到下面的代碼可能造成的問題。我已經在javascript中註釋了一些東西，因爲我希望它直接加載到服務器上，但我認爲它將同樣好。

我還可以補充一點，我檢查了表單中的csrf-token並且它在那裏。

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") 
}); 

我們兩個人這方面的工作，我已在自己與Python工作，而我的朋友採取JS的護理-部分。我還沒有經歷足夠的Django來實際發現可能由於cookie而導致錯誤的原因。如果可以的話，我會嘗試在大多數情況下遠離cookie，但這似乎很困難。

，當然還有：回溯：

Answer 1

您使用的一個方法的功能裝飾。

這不起作用：裝飾器返回的函數期望其第一個參數是request，並且接收self。

用途：

method_decorator(csrf_protect) 
# and so on
