我有自定义用户模型。我已经读过这个问题，因为Django在迁移auth之前迁移你的应用程序会导致错误，因为自定义用户模型引用了auth.user模型。但是我没有找到解决方法。

Answer 1

您在没有迁移的应用中有一个模型，其中包含Array.Resize的外键。如the docs中所述：

但是，请注意，未迁移的应用程序不能依赖迁移的应用程序，这是因为没有迁移。这意味着通常不可能让未迁移的应用程序具有到迁移的应用程序的ForeignKey或ManyToManyField;有些情况可能有效，但最终会失败。

您必须使用外键为用户模型添加应用迁移。

Answer 2

首先尝试执行以下命令：

$ python manage.py makemigrations
$ python manage.py migrate
$ python manage.py syncdb

如果您在models.py中对模型定义进行了任何更改，则必须运行SQL迁移查询以将数据库移动到新模型。
