Ext.data.writer.Writer Example

This example shows how to implement a Writer for your Store. A Writer-enabled Store frees you from having to manually compose Ajax requests to perform CRUD actions on a Store.

Note that the js is not minified so it is readable. See writer.js.

The AjaxProxy plugged into the store in this example uses the api configuration instead of an url. 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 your web-server to allow scripts to be executed in the /examples directory.

Take note of the requests being generated in Firebug as you interact with the Grid and Form.

An Error has been simulated on the server-side: Attempting to update a record having ODD-numbered id will generate this errror. Responses from the update action will have successProperty === false along with a message. This error can be handled by listening to the "exception" event upon your proxy.
