'area'对象不是可呼叫

Question

routes.py

from app import app
from pony.orm import *
from app.models import Area


@app.route("/")
@app.route("/user/")
@db_session
def user():
    c = Area[1]
    return c

我有数据库的模型：

models.py

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)

当我在浏览器地址中打开时

localhost:8888/

我得到此错误：

  File "C:\Python34\lib\site-packages\werkzeug\test.py", line 867, in run_wsgi_app
    app_iter = app(environ, start_response)
TypeError: 'Area' object is not callable

我犯了什么错误？

我很愚蠢！这里解决方案：

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