Class Ext.data.DataWriter

Ext.data.DataWriter facilitates create, update, and destroy actions between an Ext.data.Store and a server-side framework. A Writer enabled Store will automatically manage the Ajax requests to perform CRUD actions on a Store.

Ext.data.DataWriter is an abstract base class which is intended to be extended and should not be created directly. For existing implementations, see Ext.data.JsonWriter.

Creating a writer is simple:

var writer = new Ext.data.JsonWriter();

The proxy for a writer enabled store can be configured with a simple url:

// Create a standard HttpProxy instance.
var proxy = new Ext.data.HttpProxy({
    url: 'app.php/users'
});

For finer grained control, the proxy may also be configured with an api:

// Use the api specification
var proxy = new Ext.data.HttpProxy({
    api: {
        read    : 'app.php/users/read',
        create  : 'app.php/users/create',
        update  : 'app.php/users/update',
        destroy : 'app.php/users/destroy'
    }
});

Creating a Writer enabled store:

var store = new Ext.data.Store({
    proxy: proxy,
    reader: reader,
    writer: writer
});
