【问题描述】：

我开始了 Django 1.9 的教程，我想为我的数据库使用 Mongoengine .. 当我尝试迁移数据库“CMD：python manage.py migrate”时，我遇到了这个错误

[ raise ImproperlyConfigured("settings.DATABASES 配置不正确。" django.core.exceptions.ImproperlyConfigured：settings.DATABASES 配置不正确。请提供 ENGINE 值。查看设置文档以获取更多详细信息。 ]

我的代码：settings.py

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

【解决方案1】：

您没有正确配置 settings.py 文件中的数据库。您需要 DATABASE 配置设置，而不是将其添加到 INSTALLED_APP 中。

配置

DATABASES = {
   'default' : {
      'ENGINE' : 'django_mongodb_engine',
      'NAME' : 'my_database'
   }
}

Django MongoDB Engine 还考虑了 HOST、PORT、USER、PASSWORD 和 OPTIONS 设置。

【解决方案2】：

最简单的设置文件是使用 SQLite 的单一数据库设置。这可以使用以下配置：

数据库 = { '默认'： { '引擎': 'django.db.backends.sqlite3', 'NAME': '我的数据库', } }
