我試圖調用一個python函數，它可以讓一些查詢從GNU mailman中進入我的django數據庫。當在Django之外調用函數時，Django數據庫配置不當
當mailman試圖傳遞消息時，它會導入我的python腳本。它稍後在腳本中調用一個函數來修改消息對象。我得到的錯誤是：
ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation \
for more details.
這裏是我如何配置設置，在我的文件的頂部：
from django.core.management import setup_environ
from mysite import settings
setup_environ(settings)
當我運行python manage.py執行syncdb，似乎創建數據庫的好處。這裏是我的數據庫配置：
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'django_db', # Or path to database file if using sqlite3.
'USER': 'root', # Not used with sqlite3.
'PASSWORD': 'root', # 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.
}
}
而且，我已經註釋掉我的函數的整體，使得它現在的樣子：
def f():
return
所以我不覺得這與做函數調用。
此外，我測試了python控制檯中的setup_environ行，一切都按預期工作。
此外，當我重新啓動GNU郵遞員時，我相信它必須加載它的所有腳本，這意味着它必須導入我的文件。這意味着當我重新啓動郵遞員時，這些「setup_environ」行會運行。這很好 - 我沒有錯誤。
只有當GNU郵遞員試圖傳遞一條消息時，我遇到了問題。
所以我很難過。我做運行mailman重新啓動命令爲sudo與額外的PYTHONPATH和DJANGO_SETTINGS_MODULE環境變量，但我已經手動添加到我的sys.path和os.environ dict的相關部分，它不能解決問題。此外，錯誤並不表明這是路徑問題或無法找到設置模塊。
