我正在按照Django Book中的步骤进行操作，并进入作者解释 hot wo 设置 django 项目以使用数据库的部分。我选择了mysql。

我的设置settings.py是：

DATABASES = {
    'default': {
        'ENGINE': 'mysql',               # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'mydatabase',                  # Or path to database file if using sqlite3.
        'USER': 'myname',                # Not used with sqlite3.
        'PASSWORD': 'mypassword',        # 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.
    }
}

尝试启动服务器时，会打印以下消息：

Validating models...

我用谷歌搜索了一下，发现如果您使用旧版本的 MySQLd，则可以打印此消息。所以我确保我得到了最新版本。并在交互式 python shell 中测试了导入。没关系。

任何其他建议，为什么这不起作用？

我正在开发一个全新安装的 Ubuntu 11.04 版本（Windows 7 中的 Wubi），如果这很重要的话。=)

正确的数据库设置是'django.db.backends.mysql'.
