python–创建ModelAdmin对象时没有属性’_meta’错误

我是Django的新手,我正在尝试为我的模型自定义Admin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,我不会收到任何错误,并且网站加载正常.

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])


我收到以下错误：

类型对象’BlogAdmin’没有属性’_meta’

解决方法:

当你写：

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


你在admin中注册了两个模型：Blog和BlogAdmin,你必须为它注册Model和ModelAdmin,如下所示：

admin.site.register(Blog, BlogAdmin)
