How to Remove the AcmeDemoBundle
The Symfony Standard Edition comes with a complete demo that lives inside a bundle called AcmeDemoBundle. It is a great boilerplate to refer to while starting a project, but you'll probably want to eventually remove it.
Tip
This article uses the AcmeDemoBundle as an example, but you can use these steps to remove any bundle.
1. Unregister the Bundle in the AppKernel
To disconnect the bundle from the framework, you should remove the bundle from
the AppKernel::registerBundles() method. The bundle is normally found in
the $bundles array but the AcmeDemoBundle is only registered in the
development environment and you can find it inside the if statement below:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
// app/AppKernel.php
// ...
class AppKernel extends Kernel
{
public function registerBundles()
{
$bundles = array(...);
if (in_array($this->getEnvironment(), array('dev', 'test'))) {
// comment or remove this line:
// $bundles[] = new Acme\DemoBundle\AcmeDemoBundle();
// ...
}
}
}2. Remove Bundle Configuration
Now that Symfony doesn't know about the bundle, you need to remove any
configuration and routing configuration inside the app/config directory
that refers to the bundle.
2.1 Remove Bundle Routing
The routing for the AcmeDemoBundle can be found in app/config/routing_dev.yml.
Remove the _acme_demo entry at the bottom of this file.
2.2 Remove Bundle Configuration
Some bundles contain configuration in one of the app/config/config*.yml
files. Be sure to remove the related configuration from these files. You can
quickly spot bundle configuration by looking for a acme_demo (or whatever
the name of the bundle is, e.g. fos_user for the FOSUserBundle) string in
the configuration files.
The AcmeDemoBundle doesn't have configuration. However, the bundle is
used in the configuration for the app/config/security.yml file. You can
use it as a boilerplate for your own security, but you can also remove
everything: it doesn't matter to Symfony if you remove it or not.
3. Remove the Bundle from the Filesystem
Now you have removed every reference to the bundle in your application, you
should remove the bundle from the filesystem. The bundle is located in the
src/Acme/DemoBundle directory. You should remove this directory and you
can remove the Acme directory as well.
Tip
If you don't know the location of a bundle, you can use the getPath() method to get the path of the bundle:
1
echo $this->container->get('kernel')->getBundle('AcmeDemoBundle')->getPath();3.1 Remove Bundle Assets
Remove the assets of the bundle in the web/ directory (e.g.
web/bundles/acmedemo for the AcmeDemoBundle).
4. Remove Integration in other Bundles
Note
This doesn't apply to the AcmeDemoBundle - no other bundles depend on it, so you can skip this step.
Some bundles rely on other bundles, if you remove one of the two, the other will probably not work. Be sure that no other bundles, third party or self-made, rely on the bundle you are about to remove.
Tip
If one bundle relies on another, in most cases it means that it uses
some services from the bundle. Searching for the bundle alias string may
help you spot them (e.g. acme_demo for bundles depending on AcmeDemoBundle).
Tip
If a third party bundle relies on another bundle, you can find that bundle
mentioned in the composer.json file included in the bundle directory.
