    text
    copied!<p>I am accessing a REST service which exposes these two resources, a parent resource and a child resource: </p> <pre><code>/users /users/{userId}/account </code></pre> <p>So the resource "account" is not nested within the resource "user", it has to be accessed by a second request. There are examples for such REST APIs, e.g. <a href="https://stackoverflow.com/questions/7104578/rest-complex-composite-nested-resources">here</a></p> <p>I use these models to map users and their account to the Ext Js 4 data model:</p> <p><strong>User</strong></p> <pre><code>Ext.define("MyApp.model.User", { extend: "Ext.data.Model", fields: [ { name: "id", type: "string" }], associations: [{ model: "MyApp.model.Account", name: "account", type: "hasOne", reader: "json", getterName: "getAccount", setterName: "setAccount", foreignKey: "accountId" } ], proxy: { type: "rest", url: "/rest/users", reader: { type: "json", totalProperty: "total", root: "users" } } }); </code></pre> <p><strong>Account</strong></p> <pre><code>Ext.define("MyApp.model.Account", { extend: "Ext.data.Model", fields: [ { name: "id", type: "string" }], belongsTo: "MyApp.model.User", proxy: { type: "rest", reader: { type: "json"} } }); </code></pre> <p>The account proxy does not have a url (I hoped this would be created based on the parent user model). When I call user.getAccount() I get an exception because the proxy is missing the url. </p> <p><strong>Question</strong>: <em>Is there some way to setup the models such that Ext Js will access /users/{userId}/account WITHOUT updating the account proxy url manually with each parent userId?</em></p>
