Python “区域”对象不可调用

我在Mysql上有数据库，在项目中我在Flask中使用pony orm。我需要从数据库中获取索引为1的行

这里我有在应用程序中路由的路由

routes.py 这里我有我的数据库模型

models.py 当我在浏览器地址localhost:8888/中打开时，我收到下一个错误

---

当我犯错的时候？

我很愚蠢！这里是解决方案：

def user():
    c = Area[1]
    name = c.name
    return name

看起来您正在尝试调用类而不是实例区域[1]是的，它不应该是区域[1]而不是区域[1]？如果a.id==1，请尝试为区域内的对象选择此selecta。现在我得到TypeError:“Query”对象不可调用

from pony.orm import *
import config

db = Database()


class Country(db.Entity):
    id = PrimaryKey(int,auto=True)
    name = Required(str,100)
    area = Set("Area")


class Area(db.Entity):
    id = PrimaryKey(int, auto=True)
    name = Required(str, 100)
    country = Required(Country)
