-framework can inspect the HTTP Method and act accordingly:
-<pre>
-<u>Method</u>   <u>url</u>        <u>action</u>
-POST     /users     create

Specific urls to call on CRUD action methods "read", "create", "update" and "destroy". -Defaults to: `api: { - read : undefined, - create : undefined, - update : undefined, - destroy : undefined -}` - The url is built based upon the action being executed `[load\|create\|save\|destroy]` -using the commensurate `api` property, or if undefined default to the -configured Ext.data.Store.url. - For example: - `api: { - load : '/controller/load', - create : '/controller/new', // Server MUST return idProperty of new record - save : '/controller/update', - destroy : '/controller/destroy_action' -} - -// Alternatively, one can use the object-form to specify each API-action -api: { - load: {url: 'read.php', method: 'GET'}, - create: 'create.php', - destroy: 'destroy.php', - save: 'update.php' -}` - If the specific URL for a given CRUD action is undefined, the CRUD action request -will be directed to the configured `url`. - Note: To modify the URL for an action dynamically the appropriate API -property should be modified before the action is requested using the corresponding before -action event. For example to modify the URL associated with the load action: - // modify the url for the action -myStore.on({ - beforeload: { - fn: function (store, options) { - // use setUrl to change the URL for just this request. - store.proxy.setUrl('changed1.php'); - - // set optional second parameter to true to make this URL change - // permanent, applying this URL for all subsequent requests. - store.proxy.setUrl('changed1.php', true); - - // Altering the proxy API should be done using the public - // method setApi. - store.proxy.setApi('read', 'changed2.php'); - - // Or set the entire API with a config-object. - // When using the config-object option, you must redefine the entire - // API -- not just a specific action of it. - store.proxy.setApi({ - read : 'changed_read.php', - create : 'changed_create.php', - update : 'changed_update.php', - destroy : 'changed_destroy.php' - }); - } - } -}); -	DataProxy

A config object containing one or more event handlers to be added to this -object during initialization. This should be a valid listeners config object as specified in the -addListener example for attaching multiple handlers at once. - DOM events from ExtJs Components - While some ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this -is usually only done when extra value can be added. For example the DataView's -`click` event passing the node clicked on. To access DOM -events directly from a Component's HTMLElement, listeners must be added to the Element after the Component -has been rendered. A plugin can simplify this step: // Plugin is configured with a listeners config object. -// The Component is appended to the argument list of all handler functions. -Ext.DomObserver = Ext.extend(Object, { - constructor: function(config) { - this.listeners = config.listeners ? config.listeners : config; - }, - - // Component passes itself into plugin's init method - init: function(c) { - var p, l = this.listeners; - for (p in l) { - if (Ext.isFunction(l[p])) { - l[p] = this.createHandler(l[p], c); - } else { - l[p].fn = this.createHandler(l[p].fn, c); - } - } - - // Add the listeners to the Element immediately following the render call - c.render = c.render.createSequence(function() { - var e = c.getEl(); - if (e) { - e.on(l); - } - }); - }, - - createHandler: function(fn, c) { - return function(e) { - fn.call(this, e, c); - }; - } -}); - -var combo = new Ext.form.ComboBox({ - - // Collapse combo when its element is clicked on - plugins: [ new Ext.DomObserver({ - click: function(evt, comp) { - comp.collapse(); - } - })], - store: myStore, - typeAhead: true, - mode: 'local', - triggerAction: 'all' -});	Observable

Set to `true` to operate in a RESTful manner. - Note: this parameter will automatically be set to `true` if the -Ext.data.Store it is plugged into is set to `restful: true`. If the -Store is RESTful, there is no need to set this option on the proxy. - RESTful implementations enable the serverside framework to automatically route -actions sent to one url based upon the HTTP method, for example: - `store: new Ext.data.Store({ - restful: true, - proxy: new Ext.data.HttpProxy({url:'/users'}); // all requests sent to /users - ... -)}` -If there is no `api` specified in the configuration of the proxy, -all requests will be marshalled to a single RESTful url (/users) so the serverside -framework can inspect the HTTP Method and act accordingly: - -Method url action -POST /users create -GET /users read -PUT /users/23 update -DESTROY /users/23 delete - - If set to `true`, a non-phantom record's -id will be appended to the url. Some MVC (e.g., Ruby on Rails, -Merb and Django) support segment based urls where the segments in the URL follow the -Model-View-Controller approach: `someSite.com/controller/action/id` -Where the segments in the url are typically: - The first segment : represents the controller class that should be invoked. - The second segment : represents the class function, or method, that should be called. - The third segment : represents the ID (a variable typically passed to the method). - - Refer to `Ext.data.DataProxy.api` for additional information.

There is no implementation in the Observable base class. - This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default -implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to -access the required target more quickly. - Example: Ext.override(Ext.form.Field, { - // Add functionality to Field's initComponent to enable the change event to bubble - initComponent : Ext.form.Field.prototype.initComponent.createSequence(function() { - this.enableBubble('change'); - }), - - // We know that we want Field's events to bubble directly to the FormPanel. - getBubbleTarget : function() { - if (!this.formPanel) { - this.formPanel = this.findParentByType('form'); - } - return this.formPanel; - } -}); - -var myForm = new Ext.formPanel({ - title: 'User Details', - items: [{ - ... - }], - listeners: { - change: function() { - // Title goes red if form has been modified. - myForm.header.setStyle('color', 'red'); - } - } -}); Parameters: `events` : String/Array The event name to bubble, or an Array of event names.

This event is relayed -through a corresponding Ext.data.Store.exception, -so any Store instance may observe this event. - In addition to being fired through the DataProxy instance that raised the event, this event is also fired -through the Ext.data.DataProxy class to allow for centralized processing of exception events from all -DataProxies by attaching a listener to the Ext.data.Proxy class itself. - This event can be fired for one of two reasons: - - remote-request failed : -The server did not return status === 200. - - remote-request succeeded : -The remote-request succeeded but the reader could not read the response. -This means the server returned data, but the configured Reader threw an -error while reading the response. In this case, this event will be -raised and the caught error will be passed along into this event. - - - This event fires with two different contexts based upon the 2nd -parameter `type [remote\|response]`. The first four parameters -are identical between the two contexts -- only the final two parameters -differ. Listeners will be called with the following arguments: `this` : DataProxy The proxy that sent the request `type` : String The value of this parameter will be either `'response'` or `'remote'`. - - `'response'` : - An invalid response from the server was returned: either 404, -500 or the response meta-data does not match that defined in the DataReader -(e.g.: root, idProperty, successProperty). - - `'remote'` : - A valid response was returned from the server having -successProperty === false.
