AttributeError：'設置'對象沒有任何屬性'DATABASE_ENGINE'

Im新的django和python，試圖在我的系統上運行一段Django代碼，但即時通訊運行到這些問題，即時運行版本2.7 python和v1.4 djangoAttributeError：'設置'對象沒有任何屬性'DATABASE_ENGINE'

$ python manage.py runserver

這是settings.py的部分相關的問題

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'. 
     'NAME': os.path.join(DIRNAME, 'database.sqlite3'), # Or path to database file if using sqlite3. 
     'USER': '',      # Not used with sqlite3. 
     'PASSWORD': '',     # Not used with sqlite3. 
     'HOST': '',      # Set to empty string for localhost. Not used with sqlite3. 
     'PORT': '',      # Set to empty string for default. Not used with sqlite3. 
    } 
}

我該如何解決這一問題？

請提供型號代碼來檢查模型中的字段類型。 – Nilesh 2012-02-16 08:18:14

什麼是/Users/Kinnovate/Desktop/fsdjango/platformsite/common/fields/pickle.py？它是你的代碼嗎？那麼你有一個錯誤，因爲你真的沒有DATABASE_ENGINE在你的seetings。改爲使用settings.DATABASES['default']['ENGINE']。

你失去了一些東西

因爲隨着你的回溯數據庫必須是mysql。

File "/Users/Kinnovate/Desktop/fsdjango/platformsite/common/fields/pickle.py", line 27, in <module> 
    mysql_backend = settings.DATABASE_ENGINE == 'mysql' 
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/utils/functional.py", line 186, in inner 
    return func(self._wrapped, *args)

因爲它輸入在mysql_backend = settings.DATABASE_ENGINE == 'mysql'行。

根據您的設置'ENGINE': 'django.db.backends.sqlite3',所以它必須輸入sqlite請檢查您的應用程序，因爲它可能是您的settings.py可能是從另一個地方引用。
