ValueError at/feed/- int（）與基數爲10的無效文字

Question

我需要爲一組操作顯示用戶的提要。我爲此使用了Django Activity Stream。我剛開始測試應用程序，但似乎無法顯示用戶供稿。

由於每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) 

這給了我一個錯誤

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

這裏是回溯

print type(actor_stream(request.user))評估爲<class 'actstream.gfk.GFKQuerySet'>

我甚至試圖將它作爲一個列表打印，然後打印它，但它仍然會拋出相同的錯誤。我應該如何在我的視圖中訪問演員流？

編輯 - 我使用自定義用戶模型，如果有任何區別。

Answer 1

如果你這樣做，而不是：

from actstream.models import actor_stream 

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

正如你可以在堆棧跟蹤（return int(value)）結束時看到，Django的嘗試將request.user轉換爲整數。我認爲它失敗了，因爲您使用自定義用戶模型，並且沒有在其中定義任何__int__方法。試着在你的用戶模型有這個方法：

類的usermodel（models.Model）：

# your logic here 

def __int__(self): 
    return self.pk
