無法將關鍵字'項目'解析爲字段。選擇是：身份證，名稱

Question

我使用photologue創建與Django照片庫網站。我在我的virtualenv中安裝了django-tagging，不知道它已經不再被photologue支持。現在，執行遷移後，無論何時嘗試添加照片或查看照片，我都會在/ admin/photologue/photo/upload_zip/ 處收到FieldError無法將關鍵字「項目」解析爲字段。選擇是：id，name。

我卸載並重新安裝了django，photologue，SQLite文件，並刪除了django-tagging，但問題依然存在。我也嘗試運行一個使用photologue並共享virtualenv的不同項目，並提示我執行相同的（假定具有破壞性的）遷移。

如果問題涉及多個項目，並且所有依賴關係都已全新安裝，我無法弄清楚我的系統上可能發生了什麼變化。

Answer 1

這個問題似乎來自這樣一個事實，即django標記在virtualenv上仍然存在。

在photologue後您的回溯節省了模型，Django的標記反應的發送信號，並嘗試更新任何相關標籤：

File "/home/cameron/Envs/photologue/local/lib/python2.7/site-packages/django/dispatch/dispatcher.py" in send 
    198.    response = receiver(signal=self, sender=sender, **named) 
File "/home/cameron/Envs/photologue/local/lib/python2.7/site-packages/tagging/fields.py" in _save 
    81.    Tag.objects.update_tags(kwargs['instance'], tags) 
File "/home/cameron/Envs/photologue/local/lib/python2.7/site-packages/tagging/models.py" in update_tags 
    34.           items__object_id=obj.pk)) 

在那裏，它會嘗試使用（顯然不存在了）場items ，那就是發生錯誤的地方。

我想你在venv上卸載django-tagging的方式並沒有真正起作用。你是否卸載了：​​？

供參考，在這裏再次我的評論/步驟，來重新創建VENV

...如果你VENV以某種方式損壞，最簡單的可能是重新建立新：

1. 在您VENV做：

   env pip freeze > orig_requirements.txt

   檢查orig_requirements.txt並刪除你不需要的一切。

2. 讓沒有站點包新VENV並重新安裝要求：

   mkvirtualenv --no-site-packages photoenv

   pip install -r orig_requirements.txt

3. 現在仔細檢查你在這個VENV運行Django項目時

   workon photoenv

Answer 2

那麼錯誤很簡單 - 因爲你要求數據庫中不存在的字段。由於您沒有發佈代碼，因此很難更具體。建立了一個模板，引用了一個不再存在的名爲'items'的字段？

請編輯您的問題，包括一個完整的追溯以及一些代碼，你認爲這個問題可能是。

完整的回溯會讓您更好地瞭解問題所在。
