The Rest proxy is a specialization of the AjaxProxy which simply maps the four actions (create, read, update and destroy) to RESTful HTTP verbs. For example, let's set up a Model with an inline Rest proxy

Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email'],

    proxy: {
        type: 'rest',
        url : '/users'
    }
});

Now we can create a new User instance and save it via the Rest proxy. Doing this will cause the Proxy to send a POST request to '/users':

var user = Ext.create('User', {name: 'Ed Spencer', email: 'ed@sencha.com'});

user.save(); //POST /users

Let's expand this a little and provide a callback for the Ext.data.Model.save call to update the Model once it has been created. We'll assume the creation went successfully and that the server gave this user an ID of 123:

user.save({
    success: function(user) {
        user.set('name', 'Khan Noonien Singh');

        user.save(); //PUT /users/123
    }
});

Now that we're no longer creating a new Model instance, the request method is changed to an HTTP PUT, targeting the relevant url for that user. Now let's delete this user, which will use the DELETE method:

    user.destroy(); //DELETE /users/123

Finally, when we perform a load of a Model or Store, Rest proxy will use the GET method:

//1. Load via Store

//the Store automatically picks up the Proxy from the User model
var store = Ext.create('Ext.data.Store', {
    model: 'User'
});

store.load(); //GET /users

//2. Load directly from the Model

//GET /users/123
Ext.ModelManager.getModel('User').load(123, {
    success: function(user) {
        console.log(user.getId()); //outputs 123
    }
});

Url generation

The Rest proxy is able to automatically generate the urls above based on two configuration options - appendId and format. If appendId is true (it is by default) then Rest proxy will automatically append the ID of the Model instance in question to the configured url, resulting in the '/users/123' that we saw above.

If the request is not for a specific Model instance (e.g. loading a Store), the url is not appended with an id. The Rest proxy will automatically insert a '/' before the ID if one is not already present.

new Ext.data.proxy.Rest({
    url: '/users',
    appendId: true //default
});

// Collection url: /users
// Instance url  : /users/123

The Rest proxy can also optionally append a format string to the end of any generated url:

new Ext.data.proxy.Rest({
    url: '/users',
    format: 'json'
});

// Collection url: /users.json
// Instance url  : /users/123.json

If further customization is needed, simply implement the buildUrl method and add your custom generated url onto the Request object that is passed to buildUrl. See Rest proxy's implementation for an example of how to achieve this.

Note that Rest proxy inherits from AjaxProxy, which already injects all of the sorter, filter, group and paging options into the generated url. See the AjaxProxy docs for more details.

api: {
    create  : undefined,

The url is built based upon the action being executed [create|read|update|destroy] using the commensurate api property, or if undefined default to the configured Ext.data.Store.url.

For example:

api: {
    create  : '/controller/new',
    read    : '/controller/load',
    update  : '/controller/update',
    destroy : '/controller/destroy_action'
}

If the specific URL for a given CRUD action is undefined, the CRUD action request will be directed to the configured url.

DOM events from Ext JS Components

While some Ext JS 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 itemclick event passing the node clicked on. To access DOM events directly from a child element of a Component, we need to specify the element option to identify the Component property to add a DOM listener to:

new Ext.panel.Panel({
    width: 400,
    height: 200,
    dockedItems: [{
        xtype: 'toolbar'
    }],
    listeners: {
        click: {
            element: 'el', //bind to the underlying el property on the panel

This object holds a key for any event that has a listener. ...

This object holds a key for any event that has a listener. The listener may be set directly on the instance, or on its class or a super class (via observe) or on the MVC EventBus. The values of this object are truthy (a non-zero number) and falsy (0 or undefined). They do not represent an exact count of listeners. The value for an event is truthy if the event must be fired and is falsy if there is no need to fire the event.

The intended use of this property is to avoid the expense of fireEvent calls when there are no listeners. This can be particularly helpful when one would otherwise have to call fireEvent hundreds or thousands of times. It is used like this:

 if (this.hasListeners.foo) {
     this.fireEvent('foo', this, arg1);

Adds the specified events to the list of events which this Observable may fire.

Available since: 1.1.0

Parameters

  • eventNames : Object/String...

    Either an object with event names as properties with a value of true. For example:

    this.addEvents({
        storeloaded: true,
        storecleared: true
    });
    

    Or any number of event names as separate parameters. For example:

    this.addEvents('storeloaded', 'storecleared');
    
( eventName, [fn], [scope], [options] ) : Object
Appends an event handler to this object. ...

Appends an event handler to this object. For example:

myGridPanel.on("mouseover", this.onMouseOver, this);

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

myGridPanel.on({
    cellClick: this.onCellClick,
    mouseover: this.onMouseOver,
    mouseout: this.onMouseOut,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellClick: {fn: this.onCellClick, scope: this, single: true},
    mouseover: {fn: panel.onMouseOver, scope: panel}
});

Names of methods in a specified scope may also be used. Note that scope MUST be specified to use this option:

myGridPanel.on({
    cellClick: {fn: 'onCellClick', scope: this, single: true},
    mouseover: {fn: 'onMouseOver', scope: panel}
});

Available since: 1.1.0

Parameters

  • eventName : String/Object

    The name of the event to listen for. May also be an object who's property names are event names.

  • fn : Function (optional)

    The method the event invokes, or if scope is specified, the name* of the method within the specified scope. Will be called with arguments given to fireEvent plus the options parameter described below.

  • scope : Object (optional)

    The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

  • options : Object (optional)

    An object containing handler configuration.

    Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

    This object may contain any of the following properties:

    • scope : Object

      The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

    • delay : Number

      The number of milliseconds to delay the invocation of the handler after the event fires.

    • single : Boolean

      True to add a handler to handle just the next firing of the event, and then remove itself.

    • buffer : Number

      Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

    • target : Ext.util.Observable

      Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

    • element : String

      This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

      This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

        new Ext.panel.Panel({
            title: 'The title',
            listeners: {
                click: this.handlePanelClick,
                element: 'body'
            }
        });
      
    • destroyable : Boolean (optional)

      When specified as true, the function returns A Destroyable object. An object which implements the destroy method which removes all listeners added in this call.

      Defaults to: false

    • priority : Number (optional)

      An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code.

      Combining Options

      Using the options argument, it is possible to combine different types of listeners:

      A delayed, one-time listener.

      myPanel.on('hide', this.handleClick, this, {
          single: true,
          delay: 100
      });
      

Returns

  • Object

    Only when the destroyable option is specified.

    A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

    this.btnListeners =  = myButton.on({
        destroyable: true
        mouseover:   function() { console.log('mouseover'); },
        mouseout:    function() { console.log('mouseout'); },
        click:       function() { console.log('click'); }
    });
    

    And when those listeners need to be removed:

    Ext.destroy(this.btnListeners);
    

    or

    this.btnListeners.destroy();

    Returns

    • Object

      Only when the destroyable option is specified.

      A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

      Performs a batch of Operations, in the order specified by batchOrder. ...

      Performs a batch of Operations, in the order specified by batchOrder. Used internally by Ext.data.Store's sync method. Example usage:

      myProxy.batch({
          create : [myModel1, myModel2],
          update : [myModel3],
          destroy: [myModel4, myModel5]
      });
      

      Where the myModel* above are Model instances - in this case 1 and 2 are new instances and have not been saved before, 3 has been saved previously but needs to be updated, and 4 and 5 have already been saved but should now be destroyed.

      Note that the previous version of this method took 2 arguments (operations and listeners). While this is still supported for now, the current signature is now a single options argument that can contain both operations and listeners, in addition to other options. The multi-argument signature will likely be deprecated in a future release.

      Available since: 4.0.0

      Parameters

      • options : Object

        Object containing one or more properties supported by the batch method:

        • operations : Object

          Object containing the Model instances to act upon, keyed by action name

        • listeners : Object (optional)

          Event listeners object passed straight through to the Batch - see Ext.data.Batch for details

        • batch : Ext.data.Batch/Object (optional)

          This method has been deprecated

          as of 4.1. Use callParent instead.

          Parameters

          • args : Array/Arguments

            The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

          Returns

          • Object

            Returns the result of calling the overridden method

          Call the "parent" method of the current method. ...

          Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext.define).

           Ext.define('My.Base', {
               constructor: function (x) {
                   this.x = x;
               },
          
               statics: {
                   method: function (x) {
                       return x;
                   }
               }
           });
          
           Ext.define('My.Derived', {
               extend: 'My.Base',
          
               constructor: function () {
                   this.callParent([21]);
               }
           });
          
           var obj = new My.Derived();
          
           alert(obj.x);  // alerts 21
          

          This can be used with an override as follows:

           Ext.define('My.DerivedOverride', {
               override: 'My.Derived',
          
               constructor: function (x) {
                   this.callParent([x*2]); // calls original My.Derived constructor
               }
           });
          
           var obj = new My.Derived();
          
           alert(obj.x);  // now alerts 42
          

          This also works with static methods.

           Ext.define('My.Derived2', {
               extend: 'My.Base',
          
               statics: {
                   method: function (x) {
                       return this.callParent([x*2]); // calls My.Base.method
                   }
               }
           });
          
           alert(My.Base.method(10);     // alerts 10
           alert(My.Derived2.method(10); // alerts 20
          

          Lastly, it also works with overridden static methods.

           Ext.define('My.Derived2Override', {
               override: 'My.Derived2',
          
               statics: {
                   method: function (x) {
                       return this.callParent([x*2]); // calls My.Derived2.method
                   }
               }
           });
          
           alert(My.Derived2.method(10); // now alerts 40
          

          To override a method and replace it and also call the superclass method, use callSuper. This is often done to patch a method to fix a bug.

          Available since: 4.0.0

          Parameters

          • args : Array/Arguments

            The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

          Returns

          • Object

            Returns the result of calling the parent method

          This method is used by an override to call the superclass method but bypass any overridden method. ...

          This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.

          Consider:

           Ext.define('Ext.some.Class', {
               method: function () {
                   console.log('Good');
               }
           });
          
           Ext.define('Ext.some.DerivedClass', {
               method: function () {
                   console.log('Bad');
          
                   // ... logic but with a bug ...
          
                   this.callParent();
               }
           });
          

          To patch the bug in DerivedClass.method, the typical solution is to create an override:

           Ext.define('App.paches.DerivedClass', {
               override: 'Ext.some.DerivedClass',
          
               method: function () {
                   console.log('Fixed');
          
                   // ... logic but with bug fixed ...
          
                   this.callSuper();
               }
           });
          

          The patch method cannot use callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

                In ServerProxy subclasses, the create, read, update and destroy methods all pass through to doRequest. Each ServerProxy subclass must implement the doRequest method - see Ext.data.proxy.JsonP and Ext.data.proxy.Ajax for examples. This method carries the same signature as each of the methods that delegate to it.

                Available since: 4.0.0

                Parameters

                Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. ...

                Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. 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.define('Ext.overrides.form.field.Base', {
                    override: 'Ext.form.field.Base',
                
                    //  Add functionality to Field's initComponent to enable the change event to bubble
                    initComponent: function () {
                        this.callParent();
                        this.enableBubble('change');
                    }
                });
                
                var myForm = Ext.create('Ext.form.Panel', {
                    title: 'User Details',
                    items: [{
                        ...
                    }],
                    listeners: {
                        change: function() {
                            // Title goes red if form has been modified.
                            myForm.header.setStyle('color', 'red');
                        }

                            • fn : Function (optional)

                              If the ename parameter was an event name, this is the handler function.

                            • scope : Object (optional)

                            Parameters

                            • eventName : String/Object

                              The name of the event to listen for. May also be an object who's property names are event names.

                            • fn : Function (optional)

                              The method the event invokes, or if scope is specified, the name* of the method within the specified scope. Will be called with arguments given to fireEvent plus the options parameter described below.

                            • scope : Object (optional)

                              The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

                            • options : Object (optional)

                              An object containing handler configuration.

                              Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

                              This object may contain any of the following properties:

                              • scope : Object

                                The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

                              • delay : Number

                                The number of milliseconds to delay the invocation of the handler after the event fires.

                              • single : Boolean

                                True to add a handler to handle just the next firing of the event, and then remove itself.

                              • buffer : Number

                                Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

                              • target : Ext.util.Observable

                                Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

                              • element : String

                                This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

                                This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

                                  new Ext.panel.Panel({
                                      title: 'The title',
                                      listeners: {
                                          click: this.handlePanelClick,
                                          element: 'body'
                                      }
                                  });
                                
                              • destroyable : Boolean (optional)

                                When specified as true, the function returns A Destroyable object. An object which implements the destroy method which removes all listeners added in this call.

                                Defaults to: false

                              • priority : Number (optional)

                                An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code.

                                Combining Options

                                Using the options argument, it is possible to combine different types of listeners:

                                A delayed, one-time listener.

                                myPanel.on('hide', this.handleClick, this, {
                                    single: true,
                                    delay: 100
                                });
                                

                            Returns

                            • Object

                              Only when the destroyable option is specified.

                              A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

                              this.btnListeners =  = myButton.on({
                                  destroyable: true
                                  mouseover:   function() { console.log('mouseover'); },
                                  mouseout:    function() { console.log('mouseout'); },
                                  click:       function() { console.log('click'); }
                              });
                              

                              And when those listeners need to be removed:

                              Ext.destroy(this.btnListeners);
                              

                              or

                              this.btnListeners.destroy();

                            this.relayEvents(this.getStore(), ['load']);
                            

                            The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword.

                            Parameters

                            • origin : Object

                              The Observable whose events this object is to relay.

                            • events : String[]

                              Array of event names to relay.

                            • prefix : String (optional)

                              A common prefix to prepend to the event names. For example:

                              this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
                              

                              Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

                            Returns

                            • Object

                              A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:

                              this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
                              

                              Can be undone by calling

                              Ext.destroy(this.storeRelayers);
                              

                              or

                              this.store.relayers.destroy();

                                                              // alerts "Meeeeoooowwww"
                                    

                                    As of 4.1, direct use of this method is deprecated. Use Ext.define instead:

                                    Ext.define('My.CatOverride', {
                                        override: 'My.Cat',
                                        constructor: function() {
                                            alert("I'm going to be a cat!");
                                    
                                            this.callParent(arguments);
                                    
                                            alert("Meeeeoooowwww");
                                        }
                                    });
                                    

                                    The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).

                                    Fires when this proxy's reader provides new metadata. ...

                                    Fires when this proxy's reader provides new metadata. Metadata usually consists of new field definitions, but can include any configuration data required by an application, and can be processed as needed in the event handler. This event is currently only fired for JsonReaders. Note that this event is also propagated by Ext.data.Store, which is typically where it would be handled.
