Django 模型未显示在管理页面中

这个问题我已经看过很多次了，但没有一个回答我的问题。
我添加了一个应用程序及其模型，但在管理门户中看不到它们。
我可以从shell访问模型

设置.py

    'django.contrib.auth',

    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
    'myApp',
)

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'RCOSPortal.views.home', name='home'),
    # url(r'^RCOSPortal/', include('RCOSPortal.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:

admin.site.register(Owner)

from django.contrib import admin
from myApp.models import Owner

admin.site.register(Owner)

• 确保已运行“syncdb”命令
• 创建一个 OwnerAdmin并尝试注册它
• 如果不工作，请上传您的测试 项目（包括所有文件），以便我们可以帮助您

我认为

admin.site.register（Owner）

足以将模型包含在管理站点中。在中创建管理类不是强制性的。@arulmr是。它是可选的。尝试暴力：你的解决方案是什么，请详细说明。我也有同样的问题。
