我正在用鼻子运行测试，并想利用 --failed 标志。但是，一旦我添加它，我就会收到与用户相关的模型这样的错误：
./manage.py test # works
./manage.py test --failed # fails
CommandError: One or more models did not validate:
vod.video: 'user' has a relation with model accounts.CustomUser, which has either not been installed or is abstract.
套餐：
Django==1.6.7
django-nose==1.3
nose==1.3.4
我究竟做错了什么？
更新：我没有在我的主分支上看到这个问题。在新分支中，我开始使用 django-tenant-schemas 中的 TenantTestCase 类。可能是问题的原因。
我得到的回溯：
./manage.py test --failed --traceback
nosetests --failed --verbosity=1
Creating test database for alias 'default'...
