编辑:我试着用一个新的数据库创建一个全新的django项目,再次创建了Pages应用程序并将实际文件复制到新项目中,它的工作很有魅力,所以很明显这是django的一个bug,或者是我在上一个项目上做错了什么。我希望这是第二个,因为我不想一直创建一个全新的项目!在
我是Django的新手。实际上有一个自定义模型用户,当尝试python时管理.pymigrate我有以下错误。 我使用的是django1.11和postgres数据库管理器。 注意:在英语中,是否为:“关系<;<;Pages\u account>;不存在。

some other code..

这是showmigrations的结果:
这是第一次迁移(手动添加迁移依赖项,试图解决问题)
