python - 无法将用户字段内联到 UserProfile 管理选项卡 - 'auth.User' 没有外键到 'MyApp.UserProfile'

Question

我正在尝试将用户字段添加到用户配置文件管理选项卡中，以便能够在一个选项卡中更改每个用户属性。问题是 cmd 返回:

编辑:根据商王的评论编辑了代码，但仍然引发错误:

<class 'MyApp.admin.UserProfileUserInline'>: (admin.E202) 'auth.User' has no ForeignKey to 'MyApp.UserProfile'.

事实上，我想在 UserProfile 中内联 User 或在 User 中内联 UserProfile。问题是 UserProfile 有字段 language (注意这不是语言模型)，它是 through-model 我不知道如何将它内联到用户(UserProfile 可以毫无问题地内联)，所以我正在尝试将 User 内联到 UserProfile。

管理员.py:

from django.contrib import admin
from models import *
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
admin.site.register(AdminContact)

class UserProfileInline(admin.StackedInline):
    model = UserProfile
    can_delete = False
    verbose_name_plural = 'User_Profile'
    readonly_fields  = ('languages',)

class UserProfileLanguageLevelInline(admin.TabularInline):
    model = UserProfileLanguage

class UserAdmin(BaseUserAdmin):
    inlines = (UserProfileInline, )

class UserProfileUserInline(admin.StackedInline):
    model = User

class UserProfileAdmin(admin.ModelAdmin):
    inlines = (UserProfileLanguageLevelInline,User,)

admin.site.unregister(User)
admin.site.register(User,UserAdmin)
admin.site.register(LanguageTuple)
admin.site.register(Language)
admin.site.register(Job)
admin.site.register(UserProfileLanguage)
admin.site.register(Level)
admin.site.register(UserProfile,UserProfileAdmin)

你不应该在 UserProfileAdmin 的 inlines 中有 User 模型，因为 User 是一个模型而不是一个内联管理员。像这样编辑它:

class UserProfileAdmin(admin.ModelAdmin):
    inlines = (UserProfileLanguageLevelInline, UserProfileUserInline)
