简单的webpy+mongoDB框架

1.部署准备,往mongoDB插入一些数据

     db.col.insert({name:"bot",body:"my name is bot, love:"girl"})

2.文件目录结构

3.创建配置文件config.py,使用pymongo操作mongoDB

    #config.py
    from pymongo import MongoClient
    #连接mongoDB服务
    client = MongoClient('localhost',27017)
    #连接指定数据库
    db = client['test']
    #选择指定聚合
    collection = db['col']
    cache = False

4.创建db.py, 这个文件放些增删改查方法

 import config
 import pprint
 #**k接收一个字典 例如 listing(love='girl') 查询love='girl'所有的数据
 def listing(**k):
      list = []
      li = config.collection.find(k)
      for post in li:
           print(post)
           list.append(post)
  return  list

5.创建code.py

   import web
   import view,config
   from view import render
   #设置路由
   urls = (
      '/', 'index'
   )

  class index:
         def GET(self):
             return render.base(view.listing(love='girl'))#显示love='girl'所有数据

 if __name__ == "__main__":
     app = web.application(urls, globals())
    app.internalerror = web.debugerror
    app.run()

6.创建view.py

    import web
    import db
    import config

    t_globals = dict(
        datestr=web.datestr,
    )
   render = web.template.render('templates/', cache=config.cache,
            globals=t_globals)
   render._keywords['globals']['render'] = render

  def listing(**k):
      llist = db.listing(**k)
      return render.listing(llist)

7.模板文件 base.html

   $def with (page, title=None)
   
   
    
    
 $title
      $:page
    

8.模板listing.html

  $def with (items)
  $for item in items:
      $:render.item(item)

9.item.html

 $def with (item)

 
$item['name']
 
$item['body']
