Django-Admin.py 不显示模型

Question

“给出管理员声明的每个对象都会显示在主索引页上” 这行代码指的是

class Admin: pass

django 模型中的一个简单声明会自动生成更改并将接口添加到 Django 管理主页...此功能仍然可用吗？我的 URL .py 是正确的，我已将我的应用程序添加到已安装的应用程序中，并且我的数据库设置是正确的，但我在管理页面上看不到这些对象。令人沮丧的是，因为没有抛出任何错误。我已经多次运行syncdb..甚至通过向数据库添加新字段和新对象来测试同步数据库，但仍然没有任何变化。 帮助。请。 这是我的设置.py，models.py URLs.py

class Publisher(models.Model):
    name=models.CharField(max_length=30)

除非最近情况发生了根本性的变化，否则您仍然需要一个 admin.py 来定义管理类，然后注册它。你尝试过吗？
