完成待办事件
1. url 的配置
在main.py代码中：
urls = (
'/', 'index',
'/TodoLists', 'todo.TD',
'/TodoLists/(\w+)', 'todo.TD_Simple',
)
不用修改urls配置，因为todo.TD_Simple已经含有 PATCH 方法
2. 为todo.TD_Simple类修改 PATCH 方法
加入对待办事项的状态管理
class TD_Simple: #针对单个待办事件处理类
def PATCH(self, id):
'''
按ID查询修改结果
:param id:
:return:
'''
todo = get_by_id(id)
web.header('Content-Type', 'application/json')
if not todo:
return json.dumps({'error':'没找到这条记录'})
i = web.input()
print i
title = i.get('title', None)
status = i.get('finished', None)
if title :
collection.update({'_id': ObjectId(id)}, {"$set": {'title': title}})
if status:
if status.lower() == 'yes':
finished = True
elif status.lower() == 'no':
finished = False
collection.update({'_id': ObjectId(id)}, {"$set": {'finished': finished}})
if not title and not status:
return json.dumps({'error':'您发起了一个不允许的请求'})
#修改成功
todo = get_by_id(id)
format_data = formatField(todo)
return json.dumps(format_data)
3. postman 修改 finished 状态
