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

項目中使用了xadmin, 並且我的UserProfiles 繼承了django 自帶的User,並重寫了一些字段

 

最后 在xadmin中注冊時,我按照下面這樣的方式注冊:

xadmin.site.register(UserProfiles, UserProfilesAdmin)

　　出現了上面的錯誤:

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

　　最后解決辦法是:

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

　　先注銷UserProfiels, 再重新注冊.

　　然后運行命令:

makemigrations xadmin

migrate xadmin
