python tornado 实现类禅道系统
最近楼主加班 喽， 好久没有更新我的博客了，哎，一言难尽，废话我就不说了，来开始上精华。
背景：目前市面上有很多bug管理工具，但是各有各的特点，最著名，最流行的就是禅道，一个偶然的机会接触到了python ，学到tornado后，就想着去怎么去用到实处，后来发现自己公司的除了禅道就记录bug没有什么可以用的工具了。
语言：python3 第三库 ：tornado，qiniu(用于云存储文件)，数据库用sqlite
why use tornado？很多人其实会这么问我，我感觉tornado可以实现异步，虽然现在代码还没有用到异步，我感觉还是很不错的框架，值得学习，现在很多公司都在用，个人感觉这是一个不错的，值得我们大家去学习的框架。
来看看我的需求文档
大题是这么的轮廓，那么拿到这个的时候，我会进行需求分析，
需要什么样的数据库， 数据模型之间的关系，虽然现在还是有很多地方是写死的还没有进行搜索功能的设置，但是我相信，有了现在这个demo
那么我开始来设计下我主要会结构
handlsers 存放类似flask的views
models存数据库相关的，
static存放静态
template存放模板
untils存放公共库
setting 配置文件
urls url地址映射
run 运行文件。
那么我来开始设计我的数据，其实我的数据模型也是一波三折的。
选择用了sqlalchemy，之前用过flask的sqlalchemy感觉不错

这是数据库相关的，
1 数据库配置相关的 2 3 from sqlalchemy import create_engine 4 from sqlalchemy.orm import scoped_session,sessionmaker 5 from sqlalchemy.ext.declarative import declarative_base 6 engine=create_engine('sqlite:///shebei.db',convert_unicode=True) 7 Base=declarative_base() 8 db_session=scoped_session(sessionmaker(bind=engine)) 9 def create_all(): 10 Base.metadata.create_all(engine) 11 def drop_all(): 12 Base.metadata.drop_all(engine)
其实在开发的过程中，也遇到了很多阻力，比如下载一直实现不好，比如分页，也是参照别人的实现的，
分页公共模块
class Pagination:
def __init__(self, current_page, all_item):
try:
page = int(current_page)
except:
page = 1
if page < 1:
page = 1
all_pager, c = divmod(all_item, 10)
if int(c) > 0:
all_pager += 1
self.current_page = page
self.all_pager = all_pager
@property
def start(self):
return (self.current_page - 1) * 10
@property
def end(self):
return self.current_page * 10
def string_pager(self, base_url="/index/"):
if self.current_page == 1:
prev = '<li><a href="javascript:void(0);">上一页</a></li>'
else:
prev = '<li><a href="%s%s">上一页</a></li>' % (base_url, self.current_page - 1,)
if self.current_page == self.all_pager:
nex = '<li><a href="javascript:void(0);">下一页</a></li>'
else:
nex = '<li><a href="%s%s">下一页</a></li>' % (base_url, self.current_page + 1,)
last = '<li><a href="%s%s">尾页</a></li>' % (base_url, self.all_pager,)
str_page = "".join((prev,nex,last))
return str_page
在上传文件的时候，原来存放在本地，结果呢，下载处理不好，于是乎选择了七牛，需要到七牛的官网去注册自己的账号
from qiniu import Auth,put_file,etag,urlsafe_base64_encode
import qiniu.config
access_key='uVxowDUcYx641ivtUb111WBEI4112L3D117JHNM_AOtskRh4'
secret_key='PdXU9XrXTLtp1N21bhU1Frm1FDZqE1qhjkEaE9d1xVLZ5C'
def sendfile(key,file):
q=Auth(access_key,secret_key)
bucket_name='leilei22'
token = q.upload_token(bucket_name, key)
ret, info = put_file(token, key, file)
me= ret['hash']
f=etag(file)
if me==f:
assert_t=True
else:
assert_t=False
return assert_t
解析Excel，主要用于上传测试用例
import xlrd,xlwt from xlutils.copy import copy def datacel(filepath): file=xlrd.open_workbook(filepath) me=file.sheets()[0] nrows=me.nrows porject_id_list=[] casename_list=[] case_qianzhi_list=[] case_buzhou_list=[] case_yuqi_list=[] for i in range(1,nrows): porject_id_list.append(me.cell(i,0).value) casename_list.append(me.cell(i,2).value) case_qianzhi_list.append(me.cell(i,3).value) case_buzhou_list.append(me.cell(i,4).value) case_yuqi_list.append(me.cell(i,1).value) return porject_id_list,casename_list,case_qianzhi_list,case_buzhou_list,case_yuqi_list
其实这么现在公共模块完毕了，其实现在可以着手去开始写我们的代码了，主要的代码，还有静态界面，因为前后端都是我自己，我的前端其实还是从网上找来的模板，
学习的道路是痛苦的，但是我相信我是可以成功的，
from tornado.web import RequestHandler
from models.model_py import User
class BaseHandler(RequestHandler):
@property
def db(self):
return self.application.db
def get_current_user(self):
user_id = self.get_secure_cookie('user_id')
if not user_id:
return None
return User.get_by_id(int(user_id))
基础的类集成了RequestHandler的类，，进行了一些简单的自定义，然后后续可以用这个，
进过两周的开发，已经形成了成熟的，
