在django-digest的数据库后端获取KeyError

我刚开始将django_digest集成到我的应用程序中。作为开始，我已将@httpdigest装饰器添加到我的某个视图中。如果我尝试连接它，我得到一个在django_digest/backend/db.py中引发的KeyError异常。根据我配置哪个数据库，我在不同的位置得到不同的KeyError。我正在使用Django 1.2.1，使用MySql（也使用sqlite测试过）。我正在使用所有设置选项的默认值。在django-digest的数据库后端获取KeyError

据我所见，我遵循了所有的指示，但我整天都在苦苦挣扎。我正在使用django-digest和python-digest的版本库。任何指导将不胜感激。

回溯了SQLite和MySQL的下面：使用SQLite

：

Traceback (most recent call last):

与MySQL：

    cursor = get_connection().cursor() 
    File "/home/robm/projects/gcs/server/gcs2.5/lib/python2.5/site-packages/django/db/backends/__init__.py", line 75, in cursor 
    cursor = self._cursor()

    if settings_dict['USER']: 
KeyError: 'USER'

更新 - 似乎这是特定于Django的1.2，多数据库后端。修改数据库中的包装django_digest的后端/ db.py来自：

_connection = backend.DatabaseWrapper({           
     'DATABASE_HOST': settings.DATABASE_HOST,         
     'DATABASE_NAME': settings.DATABASE_NAME,         
     'DATABASE_OPTIONS': settings.DATABASE_OPTIONS,       
     'DATABASE_PASSWORD': settings.DATABASE_PASSWORD,       
     'DATABASE_PORT': settings.DATABASE_PORT,         
     'DATABASE_USER': settings.DATABASE_USER,         
     'TIME_ZONE': settings.TIME_ZONE,           
     })

喜欢的东西：

_connection = backend.DatabaseWrapper({ 
       'HOST': settings.DATABASE_HOST, 
       'NAME': settings.DATABASE_NAME, 
       'OPTIONS': settings.DATABASE_OPTIONS, 
       'PASSWORD': settings.DATABASE_PASSWORD, 
       'PORT': settings.DATABASE_PORT, 
       'USER': settings.DATABASE_USER, 
       'TIME_ZONE': settings.TIME_ZONE, 
       })

应该修复它。

现在我已经转向使用HTTPBasicAuth而不是https，但希望下周我会有机会做一个补丁。
