Django 测试 POSTGIS 数据库 : no attribute geo_db_type

Question

我正在尝试使用两个数据库为我的应用程序运行 django 的测试套件:一个使用 postgres，另一个使用 POSTGIS。这是我的数据库配置:

'default': {
       'ENGINE': 'django.db.backends.postgresql_psycopg2',
         ...},
'POSTGIS': {
         'ENGINE': 'django.contrib.gis.db.backends.postgis',
         ...}

当我运行 python manage.py test app 时，系统提示我删除一个旧的测试数据库，当我说是时，我收到以下错误:

Destroying old test database for alias 'default'...

Answer 1

1. 您使用的是哪个版本的 Django？
2. 当您更改数据库时，您是否首先使用了适当的命令来更新数据库和它们之间的关系，即 syncdb 或 migrate？

回答这两个问题将有助于诊断问题。谢谢!
