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 - * {@link 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
-});
- *
- * @constructor Create a new DataWriter
- * @param {Object} meta Metadata configuration options (implementation-specific)
- * @param {Object} recordType Either an Array of field definition objects as specified
- * in {@link Ext.data.Record#create}, or an {@link Ext.data.Record} object created
- * using {@link Ext.data.Record#create}.
