provided by Flask-RESTful are resources. Resources are built on top of Flask pluggable views [http://flask.pocoo.org/docs/views/], giving you easy access to multiple HTTP methods just by defining methods on your view objects, you can also use standard flask view decorators [http://flask.pocoo.org/docs/views/#decorating-views]. Custom Error Handlers Error handling is a tricky problem. Your Flask application may

watchlist # 切换进包目录 $ touch __init__.py views.py errors.py models.py commands.py # 创建多个模块 我们把这个包称为程序包，包里目前包含的模块和作用如下表所示： 模块 作用 __init__.py 包构造文件，创建程序实例 views.py 视图函数 errors.py 错误处理函数 models.py 模型类 模型类 commands.py 命令函数 提示 除了包构造文件外，其他的模块文件名你可以自由修改，比如 views.py 也可 以叫 routes.py。 创建程序实例，初始化扩展的代码放到包构造文件里（__init__.py），如下所示： 第 10 章：组织你的代码 106 import os import sys from flask import Flask from flask_sqlalchemy models import User user = User.query.first() return dict(user=user) from watchlist import views, errors, commands 在构造文件中，为了让视图函数、错误处理函数和命令函数注册到程序实例上，我 们需要在这里导入这几个模块。但是因为这几个模块同时也要导入构造文件中的程 序实例，为了避免循环依赖（A
