fields.E301报错已解决

 这个问题就是数据库在迁移的时候发生了错误！

    HINT: Update the relation to point at 'settings.AUTH_USER_MODEL'.
comment.Comment.user: (fields.E301) Field defines a relation with the model 'auth.User', which has been swapped out.
    HINT: Update the relation to point at 'settings.AUTH_USER_MODEL'.

详细报错信息：

 这个报错困扰了一天的时间，站内很少有关于这块错误的指导文章，有的也没有用处，反正对我是没有用处。
