Ext 4.2使用代理保存树 [英] Ext 4.2 Using proxy to save tree
问题描述
当我使用insertChild()或Sync(),代理发送GET到服务器只有_dc参数,我应该做什么来保存我的树通过代理?
when I use insertChild() or Sync(), proxy sends GET to server with just _dc param, what I should do to save my tree via proxy?
编辑:添加的作者,现在ext做POST,但没有数据
写监听器也没有调用
added writer, now ext doing POST but with no data write listener also didn't call
Ext.define('App.model.FileTree',
{
extend : 'Ext.data.Model',
fields : [
{name : 'id', type: 'string'},
{name : 'name', mapping:'name', type: 'string'},
{name : 'text', type: 'string'},
]
});
Ext.define('App.store.FileTree', {
extend: 'Ext.data.TreeStore',
alias:'filestore',
model : 'App.model.FileTree',
proxy: {
actionMethods: {
create: 'POST',
destroy: 'DELETE',
read: 'GET',
update: 'POST'
},
type: 'ajax',
url : '/app/store/FileTree.php',
reader: {
type: 'json'
},
writer: {
type: 'json',
nameProperty: 'mapping'
}
},
listeners : {
write: function(store, operation, opts){
Ext.each(operation.records, function(record){
if (record.dirty) {
record.commit();
}
});
}
}
});
尝试添加孩子喜欢:
var tree = Ext.ComponentQuery.query('filetree')[0];
var record = tree.getSelectionModel().getSelection()[0];
record.appendChild({text:'test',name:'test',id:2,leaf:true});
tree.store.sync();
推荐答案
配置 writer 。没有作者代理不知道该怎么做。
Configure a writer inside the proxy. Without the writer proxy does not know what to do.
我在Ext 5.0中有一棵树(但它也在Ext 4.x中工作),树模式配置为:
I have a tree in Ext 5.0 (but it works also in Ext 4.x) with tree model configured this way:
Ext.define('At.model.ContinentModel',{
extend:'Ext.data.TreeModel'
,alias:'model.continentmodel'
,idProperty:'id'
,fields:[
{name:'text', type:'string', persist:true}
,{name:'iconColor', type:'string'}
]
,proxy:{
type:'ajax'
,url:'resources/service.php/tree/read/1/'
,writer:{
type:'json'
,allowSingle:false
,encode:true
,rootProperty:'data'
}
}
});
树存储配置为 autoSync:true
。 text
中的更改字段触发服务器请求,如下所示:
The tree store is configured with autoSync:true
. Changes in text
field trigger server requests that look like this:
