1. Next is the more important views.py, you will have more time here. A bit like the CS concept of aspx inside. NET, and ASPX is similar to the template HTML to be created next!

Here is a view def that I created.

From django.shortcuts import Render, Render_to_response
def  Alert (Request):    posts   =  AlertMaster.objects.all ()   #这里的alertmaster一个表的对象, Here is the output of all his    objects return render_to_response ('external.html', { ' posts ':p osts}) #第一个参数是要使用的模板名称. The second parameter, which is the dictionary used when creating a Context for the template

  folder structure: 
 
 │admin.py│models.py <-----------------model data class │tests.py│ views.py<-------------------Views-controller-Used to define DEF return request page and context│  __ init__  .py│├─migrations│  __init__  .py│  __init__  .pyc│├─static <--------------------------------use to store folders such as CSS or JS ││body.css││jquery  -1.8.2.min.js└─templates <-------------------------------this place to store the template  ajax.html Span style= "color: #993300;" ><------------------------------Ajax Request return template  alert.html <-------------- --------------main template  external.html<--------------------------Extended Template 

2.1 external.html

{% extends "alert.html"%} #继承主模板alert. html{% block content%} {% for post in posts%}<TR>                <TD>{{Post.production_day}}</TD>                 <TD>{{Post.silo}}</TD>                 <TD>{{Post.server}}</TD>                 <TD>{{Post.region}}</TD>                 <TD>{{Post.service}}</TD>                 <TD>{{POST.OSM}}</TD>                 <TD>{{POST.PAP}}</TD>                 <TD>{{Post.sla}}</TD>            </TR>{%endfor%}{% Endblock%}

2.2 alert.html

<style= "Clear:both;" class = "Altrowstable" ID = "Alternatecolor" > {%block content%}{% endblock%}          #此处预留给extended. html, easy to splice and expand the template  </ Table >

3. Ajax Request views.py

Jquery/ajax Code:

function (data) {          #URL部分 "/ajax_response/" will be redirected in urls.py

$ ("#alternatecolor"). HTML (data);});

urls.py Code:

URL (r ' ^alert/$ ', alert),     # will enter views.py in Def alert:
URL (r'^ajax_response/$', ajax_response),  #ajax URL definition (as defined by the previous block Ajax request URL) , return the Def Ajax_response method defined in views.py (block code below)

VIEWS.PY Ajax Controller Code:

defAjax_response (Request):param=request. Post.get ("param") #获取由模板ajax传来的参数Raw_sql='SELECT * from Alert.alert_master where param= "' +param+ ' 'tests=AlertMaster.objects.raw (raw_sql) #执行rawsql returnRender_to_response ('ajax.html',{'tests': Tests})#返回带新字典的ajax页面 (HTML)
