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，

 数据库配置相关的

 from sqlalchemy import  create_engine
 from  sqlalchemy.orm import  scoped_session,sessionmaker
 from sqlalchemy.ext.declarative import  declarative_base
 engine=create_engine('sqlite:///shebei.db',convert_unicode=True)
 Base=declarative_base()
 db_session=scoped_session(sessionmaker(bind=engine))
 def create_all():
     Base.metadata.create_all(engine)
 def drop_all():
     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，
