Question

我是python和flask的新手，尝试通过构建一个宁静的客户数据库来学习，所以这是在dataModels.py中：

非常简单：

class Customer(object):
    def __init__(self, pID, name, address, email, custNO, agent ):
        self.pID = pID
        self.name = name
        self.address =address
        self.email = email
        self.custNO = custNO
        self.agent = agent

class CustomerList(list):
    def addCustomer(self, pID, name, address, email, custNO, agent):
        self.append((false, pID, name, address, email, custNO, agent))
    def custCount(self):
        return len (self)

这是在views.py中：

api.add_resource(CustomerList, '/customer')

我得到一个“AttributeError：类型对象'CustomerList'没有属性'as_view'”错误。我错过了什么？

我很感激帮助。

Flask-Restful期望您将它传递给flask.ext.restful.Resource的子类，但是您传递的是一个不是Resource的子类且不提供as_view方法的类（来自flask.views.View，restful.Resource本身就是其子类。）

您需要同时制作Customer和 ~~CustomerList~~ Customers Resource子类：

class Customer(Resource):
    def __init__(self, p_id, name, address, email, customer_number, agent):
        self.p_id = p_id
        self.name = name
        self.address = address
        self.email = email
        self.customer_number = customer_number
        self.agent = agent

class Customers(Resource):
    def __init__(self, *args, **kwargs):
        super(Customers, self).__init__(*args, **kwargs)
        self._customer_list = []

    def add_customer(self, p_id, name, address, email, customer_number, agent):
        customer = Customer(p_id, name, address, email, customer_number, agent)
        self._customer_list.append(customer)

    def __len__(self):
        return len(self._customer_list)

请查看the documentation's quickstart full example，了解您正在尝试做的更全面的示例。
