xadmin.sites.AlreadyRegistered: The model UserProfiles is already registered

项目中使用了xadmin, 并且我的UserProfiles 继承了django 自带的User,并重写了一些字段

最后 在xadmin中注册时,我按照下面这样的方式注册:

xadmin.site.register(UserProfiles, UserProfilesAdmin)

　　出现了上面的错误:

xadmin.sites.AlreadyRegistered: The model UserProfiles is already registered

　　最后解决办法是:

xadmin.site.unregister(UserProfiles)
xadmin.site.register(UserProfiles, UserProfilesAdmin)

　　先注销UserProfiels, 再重新注册.

　　然后运行命令:

makemigrations xadmin

migrate xadmin
