216 "doc": "<p>Associations enable you to express relationships between different <a href=\"#/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">Models</a>. Let's say we're\nwriting an ecommerce system where Users can make Orders - there's a relationship between these Models that we can\nexpress like this:</p>\n\n\n\n\n<pre><code>Ext.define('User', {\n extend: 'Ext.data.Model',\n fields: ['id', 'name', 'email'],\n\n hasMany: {model: 'Order', name: 'orders'}\n});\n\nExt.define('Order', {\n extend: 'Ext.data.Model',\n fields: ['id', 'user_id', 'status', 'price'],\n\n belongsTo: 'User'\n});\n</code></pre>\n\n\n\n\n<p>We've set up two models - User and Order - and told them about each other. You can set up as many associations on\neach Model as you need using the two default types - <a href=\"#/api/Ext.data.HasManyAssociation\" rel=\"Ext.data.HasManyAssociation\" class=\"docClass\">hasMany</a> and\n<a href=\"#/api/Ext.data.BelongsToAssociation\" rel=\"Ext.data.BelongsToAssociation\" class=\"docClass\">belongsTo</a>. There's much more detail on the usage of each of those inside their\ndocumentation pages. If you're not familiar with Models already, <a href=\"#/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">there is plenty on those too</a>.</p>\n\n\n\n\n<p><u>Further Reading</u></p>\n\n\n\n\n<ul style=\"list-style-type: disc; padding-left: 20px;\">\n <li><a href=\"#/api/Ext.data.HasManyAssociation\" rel=\"Ext.data.HasManyAssociation\" class=\"docClass\">hasMany associations</a>\n <li><a href=\"#/api/Ext.data.BelongsToAssociation\" rel=\"Ext.data.BelongsToAssociation\" class=\"docClass\">belongsTo associations</a>\n <li><a href=\"#/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">using Models</a>\n</ul>\n\n\n<p><b>Self association models</b></p>\n\n<p>We can also have models that create parent/child associations between the same type. Below is an example, where\ngroups can be nested inside other groups:</p>\n\n\n<pre><code>\n// Server Data\n{\n \"groups\": {\n \"id\": 10,\n \"parent_id\": 100,\n \"name\": \"Main Group\",\n \"parent_group\": {\n \"id\": 100,\n \"parent_id\": null,\n \"name\": \"Parent Group\"\n },\n \"child_groups\": [{\n \"id\": 2,\n \"parent_id\": 10,\n \"name\": \"Child Group 1\"\n },{\n \"id\": 3,\n \"parent_id\": 10,\n \"name\": \"Child Group 2\"\n },{\n \"id\": 4,\n \"parent_id\": 10,\n \"name\": \"Child Group 3\"\n }]\n }\n}\n\n// Client code\nExt.define('Group', {\n extend: 'Ext.data.Model',\n fields: ['id', 'parent_id', 'name'],\n proxy: {\n type: 'ajax',\n url: 'data.json',\n reader: {\n type: 'json',\n root: 'groups'\n }\n },\n associations: [{\n type: 'hasMany',\n model: 'Group',\n primaryKey: 'id',\n foreignKey: 'parent_id',\n autoLoad: true,\n associationKey: 'child_groups' // read child data from child_groups\n }, {\n type: 'belongsTo',\n model: 'Group',\n primaryKey: 'id',\n foreignKey: 'parent_id',\n autoLoad: true,\n associationKey: 'parent_group' // read parent data from parent_group\n }]\n});\n\n\nExt.onReady(function(){\n \n Group.load(10, {\n success: function(group){\n console.log(group.getGroup().get('name'));\n \n group.groups().each(function(rec){\n console.log(rec.get('name'));\n });\n }\n });\n \n});\n</code></pre>\n\n",
