问题描述

我正在尝试更新编辑器网格中显示的记录。而不是更新相同的记录,一个新的记录被插入到数据库...我在哪里缺少?pllzz帮助。以下是我的JsonStore代码: / p>

  Ext.data.Api.restActions = {
create:'POST',
read:'GET ',
update:'PUT',
destroy:'DELETE'};

ProdStore = Ext.extend(Ext.data.JsonStore,{
constructor:function(cfg){
cfg = cfg || {};
ProdStore。 superclass.constructor.call(this,Ext.apply({
storeId:'ProdStore',
id:'ProdStore',
url:'products.json',
root :'proddata',
restful:true,
idProperty:'id',
successProperty:'success',
autoLoad:true,
autoSave:false,
批次:true,
作者:新Ext.data.JsonWriter({
encode:false,
listful:false,
writeAllFields:false}),

字段:[
{name:'customer_id'},{name:'prodnm'},
{name:'qty'},{name:'rate'},{name :'amt'}
]

},cfg));
}
});
new ProdStore();


解决方案

商店中设置的idProperty应该是表示数据库中的唯一行。在这种情况下可能是customer_id?



如果这不能解决问题,我将不得不看到后端代码来查看如何处理保存。 >

i am trying to update records displayed in editor grid..but instead of updating same record, a new record gets inserted into the database...what am i missing??pllzz help..following is my JsonStore code :

Ext.data.Api.restActions = {
create  : 'POST',
read    : 'GET',
update  : 'PUT',
destroy : 'DELETE' };

ProdStore = Ext.extend(Ext.data.JsonStore, {
    constructor: function(cfg) {
        cfg = cfg || {};
        ProdStore.superclass.constructor.call(this, Ext.apply({
            storeId: 'ProdStore',
            id:'ProdStore',
            url: 'products.json',
            root: 'proddata',
            restful:true,
            idProperty:'id',
            successProperty:'success',
            autoLoad:true,
            autoSave:false,
            batch:true,
            writer: new Ext.data.JsonWriter({
            encode: false,
            listful: false,
            writeAllFields: false}),

            fields: [
                {   name:'customer_id'},{ name: 'prodnm'},
                {   name: 'qty'}, { name: 'rate' }, {   name: 'amt'}
            ]

        }, cfg));
    }
});
new ProdStore();

解决方案

The idProperty set on the store should be the field that represents unique rows in the database. Perhaps customer_id in this case?

If this does not fix the issue, I would have to see the back end code to see how the save is being handled.
