Using ModelsRepresents a one to one association with another model. The owner model is expected to have a foreign key which references the primary key of the associated model:
Ext.define('Person', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'id', type: 'int' },
{ name: 'name', type: 'string' },
{ name: 'address_id', type: 'int'}
],
// we can use the hasOne shortcut on the model to create a hasOne association
associations: { type: 'hasOne', model: 'Address' }
}
});
Ext.define('Address', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'id', type: 'int' },
{ name: 'number', type: 'string' },
{ name: 'street', type: 'string' },
{ name: 'city', type: 'string' },
{ name: 'zip', type: 'string' },
]
}
});
In the example above we have created models for People and Addresses, and linked them together by saying that each Person has a single Address. This automatically links each Person to an Address based on the Persons address_id, and provides new functions on the Person model:
Generated getter function
The first function that is added to the owner model is a getter function:
var person = Ext.create('Person', {
id: 100,
address_id: 20,
name: 'John Smith'
});
person.getAddress(function(address, operation) {
// do something with the address object
alert(address.get('id')); // alerts 20
}, this);
The getAddress function was created on the Person model when we defined the association. This uses the Persons configured proxy to load the Address asynchronously, calling the provided callback when it has loaded.
The new getAddress function will also accept an object containing success, failure and callback properties - callback will always be called, success will only be called if the associated model was loaded successfully and failure will only be called if the associatied model could not be loaded:
person.getAddress({
reload: true, // force a reload if the owner model is already cached
callback: function(address, operation) {}, // a function that will always be called
success : function(address, operation) {}, // a function that will only be called if the load succeeded
failure : function(address, operation) {}, // a function that will only be called if the load did not succeed
scope : this // optionally pass in a scope object to execute the callbacks in
});
In each case above the callbacks are called with two arguments - the associated model instance and the operation object that was executed to load that instance. The Operation object is useful when the instance could not be loaded.
Once the getter has been called on the model, it will be cached if the getter is called a second time. To force the model to reload, specify reload: true in the options object.
Generated setter function
The second generated function sets the associated model instance - if only a single argument is passed to the setter then the following two calls are identical:
// this call...
person.setAddress(10);
// is equivalent to this call:
person.set('address_id', 10);
An instance of the owner model can also be passed as a parameter.
If we pass in a second argument, the model will be automatically saved and the second argument passed to the owner model's save method:
person.setAddress(10, function(address, operation) {
// the address has been saved
alert(address.get('address_id')); //now alerts 10
});
//alternative syntax:
person.setAddress(10, {
callback: function(address, operation), // a function that will always be called
success : function(address, operation), // a function that will only be called if the load succeeded
failure : function(address, operation), // a function that will only be called if the load did not succeed
scope : this //optionally pass in a scope object to execute the callbacks in
})
Customisation
Associations reflect on the models they are linking to automatically set up properties such as the primaryKey and foreignKey. These can alternatively be specified:
Ext.define('Person', {
extend: 'Ext.data.Model',
config: {
fields: [
// ...
],
associations: [
{ type: 'hasOne', model: 'Address', primaryKey: 'unique_id', foreignKey: 'addr_id' }
]
}
});
Here we replaced the default primary key (defaults to 'id') and foreign key (calculated as 'address_id') with our own settings. Usually this will not be needed.
Available since: 2.0.0
Config options
The full class name or reference to the class that the ownerModel is being associated with. This is a required configuration on every association.
Available since: 1.1.0
The name for the associated model. This defaults to the last part of the class name of the associatedModel.
Available since: 2.0.0
The name of the property in the data to read the association from. Defaults to the associatedName plus _id.
Available since: 2.0.0
The name of the foreign key on the owner model that links it to the associated model. Defaults to the lowercased name of the associated model plus "_id", e.g. an association with a model called Person would set up a address_id foreign key.
Ext.define('Person', {
extend: 'Ext.data.Model',
fields: ['id', 'name', 'address_id'], // refers to the id of the address object
hasOne: 'Address'
});
Ext.define('Address', {
extend: 'Ext.data.Model',
fields: ['id', 'number', 'street', 'city', 'zip'],
belongsTo: 'Person'
});
var Person = new Person({
id: 1,
name: 'John Smith',
address_id: 13
}, 1);
person.getAddress(); // Will make a call to the server asking for address_id 13
Available since: 2.0.0
The name of the getter function that will be added to the local model's prototype. Defaults to 'get' + the name of the foreign model, e.g. getAddress
Available since: 2.0.0
The full class name or reference to the class that owns this associations. This is a required configuration on every association.
Available since: 1.1.0
The name for the owner model. This defaults to the last part of the class name of the ownerModel.
Available since: 2.0.0
The name of the primary key on the associated model. Defaults to 'id'. In general this will be the Ext.data.Model.idProperty of the Model.
Defaults to: 'id'
Available since: 1.1.0
A special reader to read associated data
A special reader to read associated data
Available since: 2.0.0
The name of the setter function that will be added to the local model's prototype. Defaults to 'set' + the name of the foreign model, e.g. setAddress
Available since: 2.0.0
The type configuration can be used when creating associations using a configuration object. Use 'hasMany' to create a HasMany association
associations: [{
type: 'hasMany',
model: 'User'
}]
