刚添加geoDjango并将数据库移至PostGIS。我有一堆单独测试的单元测试，但是当一起运行时，我得到一个IntenalError数据库在测试之间脾气暴躁。在这些测试中使用的模型是django.contrib.gis.db模型。测试甚至继承自TransactionTestCase而不是常规的TestCase类。两者的情况相同。有趣的是，当我切换回MySQL时，它们都运行得很好。但是我不能停留在MySQL上，因为我需要下一步编写距离查询。即使在使用TransactionTestCase时，在Django中使用PostGIS获取“InternalError：no such savepoint”
如何使用postgres在geoDjango中自动执行这些测试？我该怎么办？
P.S. YES：我settings.py东西：
DATABASE_ENGINE = 'postgresql_psycopg2'
.....
TEST_RUNNER='django.contrib.gis.tests.run_tests'
POSTGIS_TEMPLATE='template_postgis'
POSTGIS_SQL_PATH='/usr/share/postgresql-8.3-postgis/'
这里的堆栈跟踪：
