4 "doc": "<p>Represents a many to one association with another model. The owner model is expected to have\na foreign key which references the primary key of the associated model:</p>\n\n\n\n\n<pre><code>Ext.define('Category', {\n extend: 'Ext.data.Model',\n fields: [\n {name: 'id', type: 'int'},\n {name: 'name', type: 'string'}\n ]\n});\n\nExt.define('Product', {\n extend: 'Ext.data.Model',\n fields: [\n {name: 'id', type: 'int'},\n {name: 'category_id', type: 'int'},\n {name: 'name', type: 'string'}\n ],\n // we can use the belongsTo shortcut on the model to create a belongsTo association\n belongsTo: {type: 'belongsTo', model: 'Category'}\n});\n</code></pre>\n\n\n<p>In the example above we have created models for Products and Categories, and linked them together\nby saying that each Product belongs to a Category. This automatically links each Product to a Category\nbased on the Product's category_id, and provides new functions on the Product model:</p>\n\n\n\n\n<p><u>Generated getter function</u></p>\n\n\n\n\n<p>The first function that is added to the owner model is a getter function:</p>\n\n\n\n\n<pre><code>var product = new Product({\n id: 100,\n category_id: 20,\n name: 'Sneakers'\n});\n\nproduct.getCategory(function(category, operation) {\n //do something with the category object\n alert(category.get('id')); //alerts 20\n}, this);\n</code></pre>\n\n\n\n\n<p>The getCategory function was created on the Product model when we defined the association. This uses the\nCategory's configured <a href=\"#/api/Ext.data.proxy.Proxy\" rel=\"Ext.data.proxy.Proxy\" class=\"docClass\">proxy</a> to load the Category asynchronously, calling the provided\ncallback when it has loaded.</p>\n\n\n\n\n<p>The new getCategory function will also accept an object containing success, failure and callback properties\n- callback will always be called, success will only be called if the associated model was loaded successfully\nand failure will only be called if the associatied model could not be loaded:</p>\n\n\n\n\n<pre><code>product.getCategory({\n callback: function(category, operation) {}, //a function that will always be called\n success : function(category, operation) {}, //a function that will only be called if the load succeeded\n failure : function(category, operation) {}, //a function that will only be called if the load did not succeed\n scope : this //optionally pass in a scope object to execute the callbacks in\n});\n</code></pre>\n\n\n\n\n<p>In each case above the callbacks are called with two arguments - the associated model instance and the\n<a href=\"#/api/Ext.data.Operation\" rel=\"Ext.data.Operation\" class=\"docClass\">operation</a> object that was executed to load that instance. The Operation object is\nuseful when the instance could not be loaded.</p>\n\n\n\n\n<p><u>Generated setter function</u></p>\n\n\n\n\n<p>The second generated function sets the associated model instance - if only a single argument is passed to\nthe setter then the following two calls are identical:</p>\n\n\n\n\n<pre><code>//this call\nproduct.setCategory(10);\n\n//is equivalent to this call:\nproduct.set('category_id', 10);\n</code></pre>\n\n\n<p>If we pass in a second argument, the model will be automatically saved and the second argument passed to\nthe owner model's <a href=\"#/api/Ext.data.Model-method-save\" rel=\"Ext.data.Model-method-save\" class=\"docClass\">save</a> method:</p>\n\n\n<pre><code>product.setCategory(10, function(product, operation) {\n //the product has been saved\n alert(product.get('category_id')); //now alerts 10\n});\n\n//alternative syntax:\nproduct.setCategory(10, {\n callback: function(product, operation), //a function that will always be called\n success : function(product, operation), //a function that will only be called if the load succeeded\n failure : function(product, operation), //a function that will only be called if the load did not succeed\n scope : this //optionally pass in a scope object to execute the callbacks in\n})\n</code></pre>\n\n\n\n\n<p><u>Customisation</u></p>\n\n\n\n\n<p>Associations reflect on the models they are linking to automatically set up properties such as the\n<a href=\"#/api/Ext.data.BelongsToAssociation-cfg-primaryKey\" rel=\"Ext.data.BelongsToAssociation-cfg-primaryKey\" class=\"docClass\">primaryKey</a> and <a href=\"#/api/Ext.data.BelongsToAssociation-cfg-foreignKey\" rel=\"Ext.data.BelongsToAssociation-cfg-foreignKey\" class=\"docClass\">foreignKey</a>. These can alternatively be specified:</p>\n\n\n\n\n<pre><code>Ext.define('Product', {\n fields: [...],\n\n associations: [\n {type: 'belongsTo', model: 'Category', primaryKey: 'unique_id', foreignKey: 'cat_id'}\n ]\n});\n </code></pre>\n\n\n\n\n<p>Here we replaced the default primary key (defaults to 'id') and foreign key (calculated as 'category_id')\nwith our own settings. Usually this will not be needed.</p>\n\n",
