python tornado 實現類禪道系統

   最近樓主加班 嘍， 很久沒有更新個人博客了，哎，一言難盡，廢話我就不說了，來開始上精華。

背景：目前市面上有不少bug管理工具，可是各有各的特色，最著名，最流行的就是禪道，一個偶然的機會接觸到了python ，學到tornado後，就想着去怎麼去用到實處，後來發現本身公司的除了禪道就記錄bug沒有什麼能夠用的工具了。

語言：python3 第三庫 ：tornado，qiniu(用於雲存儲文件)，數據庫用sqlite

why  use tornado？不少人其實會這麼問我，我感受tornado能夠實現異步，雖然如今代碼尚未用到異步，我感受仍是很不錯的框架，值得學習，如今不少公司都在用，我的感受這是一個不錯的，值得咱們你們去學習的框架。

來看看個人需求文檔

大題是這麼的輪廓，那麼拿到這個的時候，我會進行需求分析，

須要什麼樣的數據庫， 數據模型之間的關係，雖然如今仍是有不少地方是寫死的尚未進行搜索功能的設置，可是我相信，有了如今這個demo

那麼我開始來設計下我主要會結構

handlsers 存放相似flask的views

models存數據庫相關的，

static存放靜態

template存放模板

untils存放公共庫

setting 配置文件

urls url地址映射

run 運行文件。

 那麼我來開始設計個人數據，其實個人數據模型也是一波三折的。

選擇用了sqlalchemy，以前用過flask的sqlalchemy感受不錯

 這是數據庫相關的，

 1 數據庫配置相關的
 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)

 

其實在開發的過程當中，也遇到了不少阻力，好比下載一直實現很差，好比分頁，也是參照別人的實現的，

分頁公共模塊

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);">上一頁</a></li>'
        else:
            prev = '<li><a href="%s%s">上一頁</a></li>' % (base_url, self.current_page - 1,)
        if self.current_page == self.all_pager:
            nex = '<li><a href="javascript:void(0);">下一頁</a></li>'
        else:
            nex = '<li><a href="%s%s">下一頁</a></li>' % (base_url, self.current_page + 1,)
        last = '<li><a href="%s%s">尾頁</a></li>' % (base_url, self.all_pager,)
        str_page = "".join((prev,nex,last))
        return str_page

 

在上傳文件的時候，原來存放在本地，結果呢，下載處理很差，因而乎選擇了七牛，須要到七牛的官網去註冊本身的帳號

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，主要用於上傳測試用例

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

其實這麼如今公共模塊完畢了，其實如今能夠着手去開始寫咱們的代碼了，主要的代碼，還有靜態界面，由於先後端都是我本身，個人前端其實仍是從網上找來的模板，

學習的道路是痛苦的，可是我相信我是能夠成功的，

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))

 基礎的類集成了RequestHandler的類，，進行了一些簡單的自定義，而後後續能夠用這個，

進過兩週的開發，已經造成了成熟的，
