'函數'對象在Django中沒有屬性'用戶'錯誤？

Question

我在使用時出現此錯誤： @login_required('/login_backend/')在我的意見中。

我正在使用Django 1.5。我的用戶型號是：

class User(AbstractBaseUser): 
    #id = models.IntegerField(primary_key=True) 
    #identifier = models.CharField(max_length=40, unique=True, db_index=True) 
    username = models.CharField(max_length=90, unique=True, db_index=True) 
    create_time = models.DateTimeField(null=True, blank=True) 
    update_time = models.DateTimeField(null=True, blank=True) 
    email = models.CharField(max_length=225) 
    #password = models.CharField(max_length=120) 
    external = models.IntegerField(null=True, blank=True) 
    deleted = models.IntegerField(null=True, blank=True) 
    purged = models.IntegerField(null=True, blank=True) 
    form_values_id = models.IntegerField(null=True, blank=True) 
    disk_usage = models.DecimalField(null=True, max_digits=16, decimal_places=0, blank=True) 
    #last_login = models.DateTimeField() 

    objects = UserManager() 
    USERNAME_FIELD = 'email' 
    class Meta: 
     db_table = u'galaxy_user' 

如何解決這個問題？

編輯：我的視圖代碼：

def login_backend(request): 
    if request.method == 'POST': 
     username = request.POST['username'] 
     password = request.POST['password'] 
     user = authenticate(username=username, password=password) 
     if user is not None: 
      login(request, user) 
      return HttpResponseRedirect('/overview/') 
     else: 
      return HttpResponseRedirect('/login_backend/') 
    else: 
     return render_to_response('login_backend.html', context_instance=RequestContext(request)) 

@login_required('/login_backend/') 
def logout_view(request): 
    logout(request) 
    return HttpResponseRedirect('/login_backend/') 

@login_required('/login_backend/') 
def show_files(request): 
    try: 
     log_id = request.user.id 
     username = request.user.username 
     b = File.objects.filter(users_id=log_id, flag='F', flag_r='S') # Get the user id from session .delete() to use delete 
     total_files = File.objects.filter(users_id=log_id, flag='F').count() 
     total_size = File.objects.filter(users_id=log_id, flag='F').aggregate(Sum('size_overview')) 
     total_size = total_size['size_overview__sum'] 
     total_size = size(total_size, system=alternative) 
     return render_to_response('overview.html', {'overview_files': b, 'total_files':total_files, 'total_size':total_size, 'username': username}, context_instance=RequestContext(request)) 
    except TypeError: 
     return render_to_response('overview.html', {'overview_files': b, 'total_files':total_files, 'total_size':total_size, 'username': username}, context_instance=RequestContext(request))

Answer 1

這個問題似乎是不正確的使用login_required裝飾的。根據the documentation，裝飾器需要兩個可選的關鍵字參數，redirect_field_name和login_url。重點表達關鍵字參數。

我不完全確定你想用decorator的參數'/login_backend/'來達到什麼目的，但是如果你直接把它作爲第一個參數傳遞，那麼裝飾器將把它作爲你想裝飾的函數和壞東西發生。

要解決（這只是一種猜測對我而言），嘗試

@login_required(login_url='/login_backend/') 

Answer 2

from django.utils.decorators import method_decorator 


@method_decorator(login_required(login_url='/login/')) 
def startPage(request): 
    .... 
    .... 

這可能有助於 乾杯。
