Python 没有属性'_meta&x27；创建ModelAdmin对象时出错

我是Django的新手，我试图为我的模型定制管理界面，但在尝试添加ModelAdmin对象时出错。我的代码和错误包含在下面。如果我从register语句中取出BlogAdmin对象，我不会得到任何错误，并且站点加载良好

谢谢你的帮助

class Blog(models.Model):
    name = models.CharField(max_length=300)
    url = models.URLField()

class BlogAdmin(admin.ModelAdmin):
    list_display = ['name', 'url']
    search_fields = ["name"]

admin.site.register([Blog,BlogAdmin])

我得到以下错误：

类型对象“BlogAdmin”没有属性“\u meta”

当你写作时：

admin.site.register([Blog, BlogAdmin])

您在admin中注册了两个模型：

Blog

和

BlogAdmin

，您必须为它注册

Model

和

ModelAdmin

，如下所示：

admin.site.register(Blog, BlogAdmin) 

---

但是，如果有，例如：1。博客，博客管理员2。图书馆管理员那我怎样才能在once@PawankumarDubey你可以这样做。admin.site.register（[Blog，BlogAdmin]）admin.site.register（[Library，LibraryAdmin]））
