    <p>this is more of a 'best practice' question than an actual problem:</p> <p>I'm working on a project in Symfony 2 and I've built a bundle to handle all of my webservices. Basically one controller takes some JSON data, sends it off to another controller to check it matches a described format, then off to another controller to handle the database calls and eventually back to the initial controller to return a JSON response. </p> <p>I'm sending data between controllers by doing something like this:</p> <pre><code>$controller = new \Acme\myBundle\Controller\DefaultController; $response = $controller-&gt;function(); </code></pre> <p>This works correctly, but I keep coming across one problem. In the controller I pass data to I need to instantiate AppKernel and call the boot function for any Symfony function to work. This to me seems a little bit silly which leads me to believe I may be doing this all wrong. </p> <p>Any suggestions or tips appreciated!</p> <p><strong>EDIT/UPDATE</strong> Thank you all for the comments. I have set up my controllers as services, the services are working but I am still needing to manually boot/instantiate the kernel when I call a service from inside a service. </p> <pre><code>#config.yml # API Services services: service.handler: class: Acme\APIBundle\Controller\ServicesController arguments: container: "@service_container" service.definitions: class: Acme\APIBundle\Controller\DefinitionController arguments: container: "@service_container" </code></pre> <p>From another bundles controller I can then call a function from either of those services without problem: </p> <pre><code> $test = $this-&gt;get("service.handler")-&gt;testFunction(); $test2 = $this-&gt;get("service.definitions")-&gt;anotherTestFunction(); </code></pre> <p>Where I DO have a problem is if I call a function inside of one service, then try to call another service from inside that service I get the following PHP error</p> <pre><code>Fatal error: Call to a member function get() on a non-object in /vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Controller/Controller.php on line 188 </code></pre> <p>I can avoid that error by using this function and calling it rather than using $this</p> <pre><code> public function bootKernel(){ //boot kernel $controller = new \Acme\myBundle\Controller\DefaultController; $kernel = new \AppKernel('dev', true);$kernel-&gt;loadClassCache(); $kernel-&gt;boot(); $controller-&gt;setContainer($kernel-&gt;getContainer()); return($controller); } </code></pre> <p>I guess my solution 'works' but it certainly doesn't seem an efficient way to do things. </p> <p><strong>EDIT 2:</strong> If I stick this at the top of the class then modify the service call it seems to work... Still not sure if this is the best way to do things. </p> <pre><code> protected $container; public function __construct($container) { $this-&gt;container= $container; } </code></pre>

    1. COI think the [forwarding](http://symfony.com/doc/current/book/controller.html#forwarding) may be an option here.

    2. COIs there a reason you're not using [services](http://symfony.com/doc/current/cookbook/controller/service.html) to handle your different methods?

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.
