Question

我开始使用Django 1.9的教程，我想将Mongoengine用于我的数据库..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。检查设置文档以获取更多详细信]

我的代码：settings.py

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

任何想法？提前谢谢！

Answer 1

您没有正确配置settings.py文件中的DATABASES。不需要在INSTALLED_APP中添加它，而是需要DATABASE配置设置。

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。

Answer 2

最简单的设置文件是使用SQLite进行单数据库设置。可以使用以下方法配置：

DATABASES = { 'default'：{ 'ENGINE'：'django.db.backends.sqlite3'， 'NAME'：'mydatabase'， }}

请参阅https://docs.djangoproject.com/en/1.10/ref/settings/#databases

使用django 1.9
