导入 UserAdmin raise AppRegistryNotReady("Models aren't loaded yet.")

Question

所以我尝试使用 OneToOneField 扩展用户模型，同时修改 UserAdmin 以显示正确的信息，这是我在导入时遇到错误的原因

from django.contrib.auth.admin import UserAdmin

我收到此错误：

django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.

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

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)

Answer 1

您应该在 market/admin.py 文件而不是 market/__init__.py 中定义管理员。

导入 UserAdmin raise AppRegistryNotReady("Models aren't loaded yet.")

Importing UserAdmin raise AppRegistryNotReady("Models aren't loaded yet.")

python

django

django-models
