For this job you should go with <code>javascriptRoutes</code> as it generates correct JS paths based on your routes.conf. You'll find usage sample in Zentask <a href="https://github.com/playframework/Play20/tree/master/samples/">sample</a> Anyway, for now you can fix your AJAX call by changing the <code>url</code> to <pre><code>url : '@routes.Application.saveDefaultPhoneForUser()', </code></pre> This way requires it to place the whole JS in template, which is wrong. It can or even should be moved to separate JS file and to make it possible you need to use javascriptRoutes. More... javascriptRoutes are not described yet in official documentation, but here's step-by-step introduction to it. Although the description looks sophisticated de facto using this way brings a lot of benefits. <h2>1. Create the common routes</h2> First you need to create common routes in <code>conf/routes</code> file: <pre><code>GET /item/:id controllers.Application.getItem(id: Long) POST /item/new controllers.Application.newItem PUT /item/:id controllers.Application.updateItem(id: Long) </code></pre> Of course, you need to create at least these three actions in <code>Application</code> controller: <ul> <li><code>getItem(Long id){ ... }</code></li> <li><code>newItem() { ... }</code></li> <li><code>updateItem(Long id) { ... }</code></li> </ul> <h2>2. Create an action translating common routes to JS</h2> <ul> <li>place it somewhere, ie. in your <code>Application</code> controller</li> <li>Let's call it <code>javascriptRoutes()</code></li> </ul> In that action you'll point the existing routes from the <code>conf/routes</code> file <pre><code>public static Result javascriptRoutes() { response().setContentType("text/javascript"); return ok( Routes.javascriptRouter("myJsRoutes", routes.javascript.Application.getItem(), routes.javascript.Application.newItem(), routes.javascript.Application.updateItem(), //inside somepackage controllers.somepackage.routes.javascript.Application.updateItem() ) ); } </code></pre> Note: Don't set any params in brackets. <h2>3. Create a route for <code>javascriptRoutes</code> action and include it in your template</h2> Route <code>conf/routes</code> <pre><code>GET /javascriptRoutes controllers.Application.javascriptRoutes </code></pre> View in <code><head></code> part of <code>/views/main.scala.html</code> <pre><code><script type="text/javascript" src='@routes.Application.javascriptRoutes()'></script> </code></pre> <h2>4. Use javascriptRoutes where you want</h2> Up from now you can use routes in JS to get the correct path without need to specify the <code>url</code> and <code>type</code>. For an example instead of: <pre><code> $('.getAjaxForThisContainer').click(function(e) { var idToGet = $("#someField").val(); $.ajax({ type : 'GET', url : '@routes.Application.getItem()', data : { id: idToGet }, success : function(data) { // ... some code on success } }); return false; }); </code></pre> you can use simplified version (<code>myJsRoutes</code> from point 2): <pre><code>myJsRoutes.controllers.Application.getItem(idToGet).ajax({ success : function(data) { ... some code ... } }); </code></pre> or <pre><code>myJsRoutes.controllers.Application.newItem().ajax({ success : function(data) { ... some code ... } }); </code></pre> etc... <ul> <li>you don't need to specify <code>type: "POST"</code> - JS router will use correct method according to <code>conf/routes</code> rule</li> <li>you can set <code>id</code> of the record (or other params) to <code>GET</code> or <code>PUT</code> (or other methods) using <code>routes-like</code> syntax in pure JS </li> <li>If your route rule contains all required params you can really minimize yours JS:</li> </ul> for route: <pre><code>GET /some/:a/:b/:c controllers.Application.getABC(a: String, b: Integer, c: String) </code></pre> JS: <pre><code>myJsRoutes.controllers.Application.getABC("a", 1, "b" ).ajax({}); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
