A Model represents some object that your application manages. For example, one might define a Model for Users, Products, Cars, or any other real-world object that we want to model in the system. Models are registered via the model manager, and are used by stores, which are in turn used by many of the data-bound components in Ext.

Models are defined as a set of fields and any arbitrary methods and properties relevant to the model. For example:

Ext.define('User', {
    extend: 'Ext.data.Model',

    config: {
        fields: [
            {name: 'name',  type: 'string'},
            {name: 'age',   type: 'int'},
            {name: 'phone', type: 'string'},
            {name: 'alive', type: 'boolean', defaultValue: true}
        ]
    },

    changeName: function() {
        var oldName = this.get('name'),
            newName = oldName + " The Barbarian";

        this.set('name', newName);
    }
});

The fields array is turned into a MixedCollection automatically by the ModelManager, and all other functions and properties are copied to the new Model's prototype.

Now we can create instances of our User model and call any model logic we defined:

var user = Ext.create('User', {
    name : 'Conan',
    age  : 24,
    phone: '555-555-5555'
});

user.changeName();
user.get('name'); //returns "Conan The Barbarian"

Validations

Models have built-in support for validations, which are executed against the validator functions in Ext.data.validations (see all validation functions). Validations are easy to add to models:

Ext.define('User', {
    extend: 'Ext.data.Model',

    config: {
        fields: [
            {name: 'name',     type: 'string'},
            {name: 'age',      type: 'int'},
            {name: 'phone',    type: 'string'},
            {name: 'gender',   type: 'string'},
            {name: 'username', type: 'string'},
            {name: 'alive',    type: 'boolean', defaultValue: true}
        ],

        validations: [
            {type: 'presence',  field: 'age'},
            {type: 'length',    field: 'name',     min: 2},
            {type: 'inclusion', field: 'gender',   list: ['Male', 'Female']},
            {type: 'exclusion', field: 'username', list: ['Admin', 'Operator']},
            {type: 'format',    field: 'username', matcher: /([a-z]+)[0-9]{2,3}/}
        ]
    }
});

The validations can be run by simply calling the validate function, which returns a Ext.data.Errors object:

var instance = Ext.create('User', {
    name: 'Ed',
    gender: 'Male',
    username: 'edspencer'
});

var errors = instance.validate();

Associations

Models can have associations with other Models via Ext.data.association.HasOne, belongsTo and hasMany associations. For example, let's say we're writing a blog administration application which deals with Users, Posts and Comments. We can express the relationships between these models like this:

Ext.define('Post', {
    extend: 'Ext.data.Model',

    config: {
        fields: ['id', 'user_id'],
        belongsTo: 'User',
        hasMany  : {model: 'Comment', name: 'comments'}
    }
});

Ext.define('Comment', {
    extend: 'Ext.data.Model',

    config: {
        fields: ['id', 'user_id', 'post_id'],
        belongsTo: 'Post'
    }
});

Ext.define('User', {
    extend: 'Ext.data.Model',

    config: {
        fields: ['id'],
        hasMany: [
            'Post',
            {model: 'Comment', name: 'comments'}
        ]
    }
});

See the docs for Ext.data.association.HasOne, Ext.data.association.BelongsTo and Ext.data.association.HasMany for details on the usage and configuration of associations. Note that associations can also be specified like this:

Ext.define('User', {
    extend: 'Ext.data.Model',

    config: {
        fields: ['id'],
        associations: [
            {type: 'hasMany', model: 'Post',    name: 'posts'},
            {type: 'hasMany', model: 'Comment', name: 'comments'}
        ]
    }
});

Using a Proxy

Models are great for representing types of data and relationships, but sooner or later we're going to want to load or save that data somewhere. All loading and saving of data is handled via a Proxy, which can be set directly on the Model:

Ext.define('User', {
    extend: 'Ext.data.Model',

    config: {
        fields: ['id', 'name', 'email'],
        proxy: {
            type: 'rest',
            url : '/users'
        }
    }
});

Here we've set up a Rest Proxy, which knows how to load and save data to and from a RESTful backend. Let's see how this works:

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

user.save(); //POST /users

Calling save on the new Model instance tells the configured RestProxy that we wish to persist this Model's data onto our server. RestProxy figures out that this Model hasn't been saved before because it doesn't have an id, and performs the appropriate action - in this case issuing a POST request to the url we configured (/users). We configure any Proxy on any Model and always follow this API - see Ext.data.proxy.Proxy for a full list.

Loading data via the Proxy is equally easy:

//get a reference to the User model class
var User = Ext.ModelManager.getModel('User');

//Uses the configured RestProxy to make a GET request to /users/123
User.load(123, {
    success: function(user) {
        console.log(user.getId()); //logs 123
    }
});

Models can also be updated and destroyed easily:

//the user Model we loaded in the last snippet:
user.set('name', 'Edward Spencer');

//tells the Proxy to save the Model. In this case it will perform a PUT request to /users/123 as this Model already has an id
user.save({
    success: function() {
        console.log('The User was updated');
    }
});

//tells the Proxy to destroy the Model. Performs a DELETE request to /users/123
user.erase({
    success: function() {
        console.log('The User was destroyed!');
    }
});

Usage in Stores

It is very common to want to load a set of Model instances to be displayed and manipulated in the UI. We do this by creating a Store:

var store = Ext.create('Ext.data.Store', {
    model: 'User'
});

//uses the Proxy we set up on Model to load the Store data
store.load();

A Store is just a collection of Model instances - usually loaded from a server somewhere. Store can also maintain a set of added, updated and removed Model instances to be synchronized with the server via the Proxy. See the Store docs for more information on Stores.

The name of a property that is used for submitting this Model's unique client-side identifier to the server when multiple phantom records are saved as part of the same Operation. In such a case, the server response should include the client id for each record so that the server response data can be used to update the client-side records if necessary. This property cannot have the same name as any of this Model's fields. Defaults to 'clientId'.

        This method has been deprecated since 2.0

        It's no longer needed to add events before firing.

        Parameters

        • eventNames : Object/String...

          Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters.

        Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.

        Combining Options

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

        A delayed, one-time listener:

        container.on('tap', this.handleTap, this, {
            single: true,
            delay: 100
        });
        

        Attaching multiple handlers in 1 call

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

        container.on({
            tap  : this.onTap,
            swipe: this.onSwipe,
        
            scope: this // Important. Ensure "this" is correct during handler execution
        });
        

        One can also specify options for each event handler separately:

        container.on({
            tap  : { fn: this.onTap, scope: this, single: true },
            swipe: { fn: button.onSwipe, scope: button }
        });
        

        See the Events Guide for more.

        Available since: 1.1.0

        Parameters

        • eventName : String

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

        • fn : Function

          The method the event invokes. 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.

          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.

          • order : String

            The order of when the listener should be added into the listener queue.

            If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

            Available options are before, current and after. Defaults to current.

          • buffer : Number

            Causes the handler to be 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.

          • element : String

            Allows you to add a listener onto a element of this component using the elements reference.

            Ext.create('Ext.Component', {
                listeners: {
                    element: 'element',
                    tap: function() {
                        console.log('element tap!');
                    }
                }
            });
            

            All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

          • delegate : String

            Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.

            // Create a container with a two children; a button and a toolbar
            var container = Ext.create('Ext.Container', {
                items: [
                    {
                       xtype: 'toolbar',
                       docked: 'top',
                       title: 'My Toolbar'
                    },
                    {
                       xtype: 'button',
                       text: 'My Button'
                    }
                ]
            });
            
            container.on({
                // Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
                delegate: 'button',
            
                tap: function() {
                    alert('Button tapped!');
                }
            });
            
        • order : String (optional)

          The order of when the listener should be added into the listener queue. Possible values are before, current and after.

          Defaults to: 'current'

                                • 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

                                      Developers should subscribe to the Ext.data.Store.update event to have their code notified of commit operations.

Stores by default will automatically remove this instance from their data collection.

                                                              The first argument is the name of the event. Every other argument passed will be available when you listen for the event.

                                                              Example

                                                              Firstly, we set up a listener for our new event.

                                                              this.on('myevent', function(arg1, arg2, arg3, arg4, options, e) {
                                                                  console.log(arg1); // true
                                                                  console.log(arg2); // 2
                                                                  console.log(arg3); // { test: 'foo' }
                                                                  console.log(arg4); // 14
                                                                  console.log(options); // the options added when adding the listener
                                                                  console.log(e); // the event object with information about the event
                                                              });
                                                              

                                                              And then we can fire off the event.

                                                              this.fireEvent('myevent', true, 2, { test: 'foo' }, 14);
                                                              

                                                              An event may be set to bubble up an Observable parent hierarchy by calling enableBubble.

                                                                                      • element : String

                                                                                                      • scope : Object

Does not update field values in a Model instance (use set for that), instead this updates which fields are available on the Model class. This is normally used when creating or updating Model definitions dynamically, for example if you allow your users to define their own Models and save the fields configuration to a database, this method allows you to change those fields later.
