在生产环境中创建Django SuperUser时发生IntegrityError

Question

我正在尝试在生产中创建超级用户以访问Django管理站点。 但是在这样做的时候我得到以下错误

File "manage.py", line 10, in <module>

django.db.utils.IntegrityError：（1048，“列'last_login'不能为空”）

我已经做了syncdb并在mysql中创建了表。 但是当尝试创建超级用户时，出现上述错误。 我尝试了其他文档，但是都没有涉及创建超级用户以及如何解决此问题。

任何线索都非常欢迎。 我在部署django时遇到了麻烦。 先感谢您

由于您使用的是管理应用，因此请不要忘记同步所有与管理相关的应用（例如会话，管理，身份验证，内容类型）。

不：

python manage.py migrate myapp

但：

python manage.py migrate
