Python xlwt生成Excel表格
今天做项目时要求完成一个巡更过程，并能够导出巡更的时间地点信息。在此做一个笔记。。
前台使用Extjs框架，具体代码如下
1. 页面的布局如下
new Ext.Viewport({
enableTabScroll:true,
layout:"border",
items:[{
region:"north",
height:64,
items:[panel]//整个系统的导航栏由js引入
},{
region:'west',
width:document.body.clientWidth*0.3,
layout:'fit',
items:[treepanel]//左边为此系统的用户列表
},{
region : 'center',
collapsible : true,
layout : 'fit',
items:[pathgrid]//中间为某用户的巡更报表信息
}]
}); - 用户列表的实现代码
var treepanel = new Ext.ux.tree.ColumnTree({
rootVisible:false,
autoScroll:true,
width:document.body.clientWidth*0.3, height:document.documentElement.clientHeight,//不加高则不会显示滚动条
border:false,
title:'用户列表' ,
columns:[{
header:'分中心名',
width:150,
dataIndex:'groupname'
},{
header:'用户名',
width:100,
dataIndex:'username'
}],
loader:new Ext.tree.TreeLoader({
dataUrl:'/control/treegridsource/',//从服务器异步加载用户数据
uiProviders:{
'col':Ext.ux.tree.ColumnNodeUI
}
}),
root:new Ext.tree.AsyncTreeNode({
text:'root',
id:'rootid'
})
});
treepanel.on('click',function(node){
if(!node.hasChildNodes()){
selectusrid=node.id;
winHistory.show();
} //点击用户列表的用户可以显示时间选择框，用户生成该用户的巡更报表
});- 时间选择窗口的实现代码（可设置时间来选择需要导出或查看的寻更信息）
var selectusrid;
var starttime;
var endtime;
function getdatetime(){//获得当前的时刻
var now = new Date;
var year = now.getYear();
var month= now.getMonth()+1;
var day=now.getDate();
var hour=now.getHours();
var minute=now.getMinutes();
if(month<10){
month="0"+month
}
if(day<10){
day='0'+day
}
if(hour<10){
hour='0'+hour
}
if(minute<10){
minute='0'+minute
}
return year+"-"+month+"-"+day+" "+hour+":"+minute;
//return year+'-'+month+'-'+day
};
function getdatetimepermon(){//获得当前时间的前一个小时时刻
var now = new Date();
var year = now.getYear();
var month= now.getMonth();
var day=now.getDate();
var hour=now.getHours();
var minute=now.getMinutes();
if(month<10){
month="0"+month
}
if(day<10){
day='0'+day
}
if(minute<10){
minute='0'+minute
}
return year+"-"+month+"-"+day+" "+hour+":"+minute;
//return year+'-'+month+'-'+day
};
//以上两个函数作为时间选择窗口的默认时间
var startdate = new Cls.form.DateTimeField({
fieldLabel:'起始时间',
emptyText:getdatetimepermon(),
name:'starttime',
anchor:'95%',
id:'startdt',
format:'Y-m-d H:i',
endDateField:'enddt'//要对应下面enddate的id
})
var enddate = new Cls.form.DateTimeField({
fieldLabel:'结束时间',
name:'endtime',
emptyText:getdatetime(),
anchor:'95%',
id:'enddt',
format:'Y-m-d H:i',
startDateField:'startdt'//要对应上面startdata的id
})
var timePanel = new Ext.form.FormPanel({
labelAlign:'left',
labelWidth:60,
width:270,
height:100,
frame:true,
bodyStyle:'padding:5px 5px 0',
items:[startdate,enddate]
})
var winHistory=new Ext.Window({
title:"时间段设置",
id:'winHistory',
closable:false,
width:270,
height:150,
buttonAlign:'center',
items:[timePanel],
resizable:false, //是否拉大窗口大小
modal:true, //窗口背面遮罩显示
buttons:[{
text:'确定',
handler: function(){
pathstore.removeAll()
starttime=Ext.get("startdt").dom.value;
endtime = Ext.get('enddt').dom.value;
pathstore.load({params:{userid:selectusrid,start:0,limit:myPageSize,starttime:starttime,endtime:endtime}});//向服务器传递参数放回巡更的时间和地点信息
winHistory.hide();
}
},{
text:'重置',
handler:function(){
timePanel.getForm().reset();
}
},{
text:'取消',
handler:function(){
winHistory.hide()
}
}]
})
- 获得某用户巡更时间地点信息的实现代码（这里的信息显示在web页面中的表格中）
var pathReader=new Ext.data.JsonReader({
totalProperty:'total',
root:'path',
fields:[{
name:'usr_name'
},{
name:'time'
},{
name:'point_name'
}]
},null)//name 要与后台返回的json字段对应
var pathstore= new Ext.data.Store({
remoteSort:true,
reader:pathReader,
proxy:new Ext.data.HttpProxy({
url:'/control/pathsource/',
timeout: 1000000
})
})- 将巡更信息显示在表格中和导出Excel报表的代码
var pathCm=new Ext.grid.ColumnModel([
new Ext.grid.RowNumberer(),
{
header:'用户名',width:120,dataIndex:'usr_name'
}, {
header:'时间',width:120,dataIndex:'time'
},{
header:'巡更点',width:120,dataIndex:'point_name'
}])//dataIndex应该与pathCm中的dataIndex字段对应
var pathgrid= new Ext.grid.GridPanel({
id:'pathgrid',
loadMask:'loading...',
cm:pathCm,
store:pathstore,
striprRows:true,
border : false,
viewConfig:{
autoScroll:true
},
bbar:new Ext.PagingToolbar({
store:pathstore,
displayInfo:true,
displayMsg:'显示{0}条到{1}条记录，共{2}条',
pageSize:myPageSize,
emptyMsg:'没有记录',
items:[{
'text':'导出路线报表',
handler:function(){
var form=$(");//定义一个form表单
form.attr("style","display:none");
form.attr("target","");
form.attr("method","post");
form.attr("action","/control/showexcel/");
var input0=$("");
input0.attr("type","hidden");
input0.attr("name","userid");
input0.attr("value",selectusrid);
var input1=$("");
input1.attr("type","hidden");
input1.attr("name","starttime");
input1.attr("value",starttime);
var input2=$("");
input2.attr("type","hidden");
input2.attr("name","endtime");
input2.attr("value",endtime);
$("body").append(form);//将表单放置在web中
//3个input中的name和value是需要向后台传递的参数
form.append(input0);
form.append(input1);
form.append(input2);
form.submit();//表单提交
}
}]
//prependButtons:true,
})
})前面页面显示如下
点击导出路线报表即可生成Excel表格
7. 此页面共3次请求后台，后台有django框架实现
1）请求用户列表代码'/control/treegridsource/'

print '22222'

print routeslice
data='{"total":%s,%s:%s}' % (length,'path',simplejson.dumps(routeslice,ensure_ascii=False))
return HttpResponse(data,mimetype='text/javascript;')3）请求导出Excel报表的后台代码"/control/showexcel/"
def showexcel(request):
user_id=request.POST.get('userid','')
logging.info(user_id)
starttime=request.POST.get('starttime','')
endtime=request.POST.get('endtime','')

#w.save('text.xls')
response = HttpResponse(mimetype='application/ms-excel')

w.save(response)
return response最终生成的Excel表格如下
django的models.py就不贴了。
