Usually created indirectly via a model definition:</p>\n\n\n\n\n<pre><code>Ext.define('Product', {\n extend: 'Ext.data.Model',\n fields: [\n {name: 'id', type: 'int'},\n {name: 'user_id', type: 'int'},\n {name: 'name', type: 'string'}\n ]\n});\n\nExt.define('User', {\n extend: 'Ext.data.Model',\n fields: [\n {name: 'id', type: 'int'},\n {name: 'name', type: 'string'}\n ],\n // we can use the hasMany shortcut on the model to create a hasMany association\n hasMany: {model: 'Product', name: 'products'}\n});\n</pre>\n\n\n<p></code></p>\n\n<p>Above we created Product and User models, and linked them by saying that a User hasMany Products. This gives\nus a new function on every User instance, in this case the function is called 'products' because that is the name\nwe specified in the association configuration above.</p>\n\n\n\n\n<p>This new function returns a specialized <a href=\"#/api/Ext.data.Store\" rel=\"Ext.data.Store\" class=\"docClass\">Store</a> which is automatically filtered to load\nonly Products for the given model instance:</p>\n\n\n\n\n<pre><code>//first, we load up a User with id of 1\nvar user = Ext.ModelManager.create({id: 1, name: 'Ed'}, 'User');\n\n//the user.products function was created automatically by the association and returns a <a href=\"#/api/Ext.data.Store\" rel=\"Ext.data.Store\" class=\"docClass\">Store</a>\n//the created store is automatically scoped to the set of Products for the User with id of 1\nvar products = user.products();\n\n//we still have all of the usual Store functions, for example it's easy to add a Product for this User\nproducts.add({\n name: 'Another Product'\n});\n\n//saves the changes to the store - this automatically sets the new Product's user_id to 1 before saving\nproducts.sync();\n</code></pre>\n\n\n\n\n<p>The new Store is only instantiated the first time you call products() to conserve memory and processing time,\nthough calling products() a second time returns the same store instance.</p>\n\n\n\n\n<p><u>Custom filtering</u></p>\n\n\n\n\n<p>The Store is automatically furnished with a filter - by default this filter tells the store to only return\nrecords where the associated model's foreign key matches the owner model's primary key. For example, if a User\nwith ID = 100 hasMany Products, the filter loads only Products with user_id == 100.</p>\n\n\n\n\n<p>Sometimes we want to filter by another field - for example in the case of a Twitter search application we may\nhave models for Search and Tweet:</p>\n\n\n\n\n<pre><code>Ext.define('Search', {\n extend: 'Ext.data.Model',\n fields: [\n 'id', 'query'\n ],\n\n hasMany: {\n model: 'Tweet',\n name : 'tweets',\n filterProperty: 'query'\n }\n});\n\nExt.define('Tweet', {\n extend: 'Ext.data.Model',\n fields: [\n 'id', 'text', 'from_user'\n ]\n});\n\n//returns a Store filtered by the filterProperty\nvar store = new Search({query: 'Sencha Touch'}).tweets();\n</code></pre>\n\n\n\n\n<p>The tweets association above is filtered by the query property by setting the <a href=\"#/api/Ext.data.HasManyAssociation-cfg-filterProperty\" rel=\"Ext.data.HasManyAssociation-cfg-filterProperty\" class=\"docClass\">filterProperty</a>, and is\nequivalent to this:</p>\n\n\n\n\n<pre><code>var store = new Ext.data.Store({\n model: 'Tweet',\n filters: [\n {\n property: 'query',\n value : 'Sencha Touch'\n }\n ]\n});\n</code></pre>\n\n",
