Represents a one-to-many relationship between two models. Usually created indirectly via a model definition:

Ext.define('Product', {
    extend: 'Ext.data.Model',
    config: {
        fields: [
            {name: 'id',      type: 'int'},
            {name: 'user_id', type: 'int'},
            {name: 'name',    type: 'string'}
        ]
    }
});

Ext.define('User', {
    extend: 'Ext.data.Model',
    config: {
        fields: [
            {name: 'id',   type: 'int'},
            {name: 'name', type: 'string'}
        ],
        // we can use the hasMany shortcut on the model to create a hasMany association
        hasMany: {model: 'Product', name: 'products'}
    }
});

`

Above we created Product and User models, and linked them by saying that a User hasMany Products. This gives us a new function on every User instance, in this case the function is called 'products' because that is the name we specified in the association configuration above.

This new function returns a specialized Store which is automatically filtered to load only Products for the given model instance:

//first, we load up a User with id of 1
var user = Ext.create('User', {id: 1, name: 'Ed'});

//the user.products function was created automatically by the association and returns a Store
//the created store is automatically scoped to the set of Products for the User with id of 1
var products = user.products();

//we still have all of the usual Store functions, for example it's easy to add a Product for this User
products.add({
    name: 'Another Product'
});

//saves the changes to the store - this automatically sets the new Product's user_id to 1 before saving
products.sync();

The new Store is only instantiated the first time you call products() to conserve memory and processing time, though calling products() a second time returns the same store instance.

Custom filtering

The Store is automatically furnished with a filter - by default this filter tells the store to only return records where the associated model's foreign key matches the owner model's primary key. For example, if a User with ID = 100 hasMany Products, the filter loads only Products with user_id == 100.

Sometimes we want to filter by another field - for example in the case of a Twitter search application we may have models for Search and Tweet:

Ext.define('Search', {
    extend: 'Ext.data.Model',
    config: {
        fields: [
            'id', 'query'
        ],

        hasMany: {
            model: 'Tweet',
            name : 'tweets',
            filterProperty: 'query'
        }
    }
});

Ext.define('Tweet', {
    extend: 'Ext.data.Model',
    config: {
        fields: [
            'id', 'text', 'from_user'
        ]
    }
});

//returns a Store filtered by the filterProperty
var store = new Search({query: 'Sencha Touch'}).tweets();

The tweets association above is filtered by the query property by setting the filterProperty, and is equivalent to this:

var store = Ext.create('Ext.data.Store', {
    model: 'Tweet',
    filters: [
        {
            property: 'query',
            value   : 'Sencha Touch'
        }
    ]
});

The name of the foreign key on the associated model that links it to the owner model. Defaults to the lowercased name of the owner model plus "_id", e.g. an association with a model called Group hasMany Users would create 'group_id' as the foreign key. When the remote store is loaded, the store is automatically filtered so that only records with a matching foreign key are included in the resulting child store. This can be overridden by specifying the filterProperty.

Ext.define('Group', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name'],
    hasMany: 'User'
});

Ext.define('User', {

                    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;
                         },

                             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

                    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".

                                          As of 2.1, 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!");
                                          
                                                  var instance = this.callParent(arguments);
                                          
                                                  alert("Meeeeoooowwww");
                                          
                                                  return instance;
                                              }
                                          });
                                          

                                          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).
