25 <h1>Ext.data.DataWriter Example</h1>
26 <p>This example shows how to implement a Writer for your Store. A Writer-enabled Store frees you from having to manually compose Ajax requests
27 to perform CRUD actions on a Store.</p>
28 <p>Note that the js is not minified so it is readable. See <a href="writer.js">writer.js</a>, <a href="UserForm.js">UserForm.js</a> and
29 <a href="UserGrid.js">UserGrid.js</a>.</p>
31 <p>The HttpProxy plugged into the store in this example uses the new <em>api</em> configuration instead of an <em>url</em>.
32 A simple MVC-like php backend has been created for this example which simulates a database by storing records in $_SESSION. See the file /remote/app/controllers/users.php. You may have to configure
33 your web-server to allow scripts to be executed in the /examples directory.</p>
36 var proxy = new Ext.data.HttpProxy({
38 read : 'app.php/users/read',
39 create : 'app.php/users/create',
40 update : 'app.php/users/update',
41 destroy : 'app.php/users/destroy'
46 <p>Take note of the requests being generated in Firebug as you interact with the Grid and Form.</p>
48 <p>An <b>Error has been simulated</b> on the server-side: Attempting to update a record having ODD-numbered id will generate this errror.
49 Responses from the update action will have successProperty === false along with a message. This error can be handled by
50 listening to the <b>"exception"</b> event upon your Store.</p>
53 exception : function(proxy, type, action, options, res, arg) {
54 if (type === 'remote') {
56 title: 'REMOTE EXCEPTION',
58 icon: Ext.MessageBox.ERROR
63 <p><b>Note: This new "exception" event supercedes the old loadexception event which is now deprecated.</b></p>
