Class Ext.data.DataProxy

Package:Ext.data
Defined In:DataProxy.js
Class:DataProxy
Subclasses:DirectProxy, HttpProxy, MemoryProxy, ScriptTagProxy
Extends:Observable

Abstract base class for implementations which provide retrieval of unformatted data objects. -This class is intended to be extended and should not be created directly. For existing implementations, -see Ext.data.DirectProxy, Ext.data.HttpProxy, Ext.data.ScriptTagProxy and -Ext.data.MemoryProxy.

-

DataProxy implementations are usually used in conjunction with an implementation of Ext.data.DataReader -(of the appropriate type which knows how to parse the data object) to provide a block of -Ext.data.Records to an Ext.data.Store.

-

The parameter to a DataProxy constructor may be an Ext.data.Connection or can also be the -config object to an Ext.data.Connection.

-

Custom implementations must implement either the doRequest method (preferred) or the -load method (deprecated). See -Ext.data.HttpProxy.doRequest or -Ext.data.HttpProxy.load for additional details.

-

Example 1

-
proxy: new Ext.data.ScriptTagProxy({
-    url: 'http://extjs.com/forum/topics-remote.php'

-}),
-

Example 2

-
proxy : new Ext.data.HttpProxy({
-    method: 'GET',
-    prettyUrls: false,
-    url: 'local/default.php', // see options parameter for Ext.Ajax.request

-    api: {
-        // all actions except the following will use above url

-        create  : 'local/new.php',
-        update  : 'local/update.php'
-    }
-}),
-

And new in Ext version 3, attach centralized event-listeners upon the DataProxy class itself! This is a great place -to implement a messaging system to centralize your application's user-feedback and error-handling.

-
// Listen to all "beforewrite" event fired by all proxies.

-Ext.data.DataProxy.on('beforewrite', function(proxy, action) {
-    console.log('beforewrite: ', action);
-});
-
-// Listen to "write" event fired by all proxies

-Ext.data.DataProxy.on('write', function(proxy, action, data, res, rs) {
-    console.info('write: ', action);
-});
-
-// Listen to "exception" event fired by all proxies

-Ext.data.DataProxy.on('exception', function(proxy, type, action) {
-    console.error(type + action + ' exception);
-});
-Note: These three events are all fired with the signature of the corresponding DataProxy instance event beforewrite, write and exception.
