ValueError at/feed/- int（）与基数为10的无效文字

Question

我需要为一组操作显示用户的提要。我为此使用了Django Activity Stream。我刚开始测试应用程序，但似乎无法显示用户供稿。

由于每Action Stream documentation我使用的actor_stream功能如下

from actstream.models import actor_stream 

def user_feed(request): 
    print actor_stream(request.user) 

这给了我一个错误

ValueError at /feed/ 
invalid literal for int() with base 10: '<property object at 0x2a6a520>' 

这里是回溯

print type(actor_stream(request.user))评估为<class 'actstream.gfk.GFKQuerySet'>

我甚至试图将它作为一个列表打印，然后打印它，但它仍然会抛出相同的错误。我应该如何在我的视图中访问演员流？

编辑 - 我使用自定义用户模型，如果有任何区别。

Answer 1

如果你这样做，而不是：

from actstream.models import actor_stream 

def user_feed(request): 
    print actor_stream(request.user.pk) # added .pk here 

正如你可以在堆栈跟踪（return int(value)）结束时看到，Django的尝试将request.user转换为整数。我认为它失败了，因为您使用自定义用户模型，并且没有在其中定义任何__int__方法。试着在你的用户模型有这个方法：

类的usermodel（models.Model）：

# your logic here 

def __int__(self): 
    return self.pk
