导入UserAdmin引发AppRegistryNotReady（“模型尚未加载。”）

So I am trying to extend the user model with a OneToOneField but also modify the UserAdmin to show the correct information which is where I am facing my error cause any time I import

因此，我尝试使用OneToOneField扩展用户模型，但也修改UserAdmin以显示正确的信息，这是我在任何时候导入错误的原因

from django.contrib.auth.admin import UserAdmin

I receive this error:

我收到此错误：

Here is the file where I am trying to modify the UserAdmin, which is copied from the Django Docs:

这是我试图修改UserAdmin的文件，它是从Django Docs复制的：

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User
from market.models import Market, MarketThemes, MarketServers, PremiumTransaction, PremiumUser, PremiumCodes, Themes, Templates, AdditionalUserSettings

class MarketAdmin(admin.ModelAdmin):
    search_fields = ['marketName', 'cName']
    list_display = ('owner', 'marketName', 'marketTheme', 'marketTemplates', 'subDomain', 'cName', 'currency', 'createdDate')


admin.site.register(Market,MarketAdmin)

class ThemeAdmin(admin.ModelAdmin):
    search_fields = ['title']
    list_display = ('owner', 'marketid', 'title', 'default')

admin.site.register(Themes,ThemeAdmin)

class ServersAdmin(admin.ModelAdmin):
    search_fields = ['serverName', 'apiKey']
    list_display = ('owner', 'marketid', 'serverName', 'apiKey')

admin.site.register(MarketServers,ServersAdmin)

admin.site.register(Templates)
admin.site.register(PremiumTransaction)
admin.site.register(PremiumUser)

class AdditionalUserSettingsInline(admin.StackedInline):
   model = AdditionalUserSettings
   can_delete=False


class CustomUserAdmin(UserAdmin):
   inlines = (AdditionalUserSettingsInline,)

admin.site.unregister(User) 
admin.site.register(User, CustomUserAdmin)

You should define the admin in the market/admin.py file instead of market/__init__.py.

您应该在market / admin.py文件中定义admin而不是market / __ init__.py。
