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DATABASES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，系统会提示我删除旧的测试数据库，当我说“是”时，我收到以下错误：

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

Answer 1

您使用的是哪个版本的Django？
当您更改数据库之前，您是否使用适当的命令更新数据库及其关系，例如syncdb或migrate？

回答这两个问题有助于诊断问题。谢谢！

Django使用POSTGIS数据库进行测试：没有属性geo_db_type
