    <p>I'd go down the <a href="http://symfony.com/doc/current/cookbook/controller/service.html" rel="noreferrer">controller-as-a-service</a> route with the above. Say you have to call 3 methods as part of your processing. Let's call them <code>foo()</code>, <code>bar()</code> and <code>something()</code>. Each of these methods are in separate controllers:</p> <pre><code>namespace Acme\DemoBundle\Controller; class FooController { public function __construct($container, ...) { $this-&gt;container = $container; // ... deal with any more arguments etc here } public function foo($params) { // ... return $x; } protected function get($service) { return $this-&gt;container-&gt;get($service); } } </code></pre> <p>Ditto for the <code>bar()</code> and <code>something()</code> methods, each in their own controller. Then, add them to your application as a service. Eg in your <code>config.yml</code> (other methods available):</p> <pre><code>services: my.foo.service: class: Acme\FooBundle\Controller\FooController arguments: container: "@service_container" </code></pre> <p>See the Symfony docs for <a href="http://symfony.com/doc/current/book/service_container.html#creating-configuring-services-in-the-container" rel="noreferrer">more details</a> about how you can construct this entry, including injecting any dependencies such as an entity manager or similar. Now, you can get an instance of this from the container:</p> <pre><code>public function yourMainAction() { // ... $newData = $this-&gt;get("my.foo.service")-&gt;fooAction($someData); // ... return new Response(json_encode($newData), ...); } </code></pre> <p>Likewise again for <code>BarController</code> and <code>SomethingController</code>. The advantage now is that this service can be made available at any point in your application (whether via the container as above, or as an injected service), across bundles, without needing to instantiate the class manually yourself and provide any dependencies.</p> <p>For more information about the container etc, the Symfony docs have a <a href="http://symfony.com/doc/2.0/book/service_container.html" rel="noreferrer">good section</a> on it (referenced in the link above).</p> <p><strong>Edit</strong>: Adjusted the code example to include details of passing in arguments into the service. Also added a convenience <code>get()</code> method to retrieve services from the container.</p>

    1. COThanks for the response, Rich. I've actually attempted using controllers as as services but ran into the exact same problem. If I call one controller as a service, then from inside that controller call another controller as a service I still need to boot the kernel each time. I've read through the docs and I'm not entirely sure which 'dependencies' I need to be setting to avoid running my boot function every time.

    2. COWithout instantiating the the kernel I get this error: Fatal error: Call to a member function get() on a non-object in /Users/greg/Repos/Acme/vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Controller/Controller.php on line 188

    3. COAre your bundles added correctly to your kernel? Inside `AppKernel.php`? They should automatically be booted if you've added them in here.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
