我对我的Django模型使用常规Django测试，使用

./manage.py test non_wagtail_app_name

但是突然之间（在添加了一些摇摆模型之后），我无法运行它们：

回溯似乎来自我项目的Wagtail部分（我的Wagtail模型使用StreamFields和BlockFields），因此我似乎遗漏了一些东西（为我的Wagtail对象放置夹具），但我不知道从哪里开始（我还没有设置Wagtail测试-是的，我知道，我应该）。我要测试的应用程序没有使用Wagtail中的任何内容

唯一有效的方法是pg_转储我的Postgres数据库，在生成的文件中编辑数据库名称，将其导入test_Postgres并将-k开关传递到manage.py test，因此很明显我需要预先填充Wagtail表。但是，在Django模型测试中使用fixture并不能解决问题…

这在运行迁移时失败。在堆栈跟踪中，我的最佳猜测是：

这是一个添加了

Stre的迁移
