How to Include External Routing Resources

How to Include External Routing Resources
Simple applications can define all their routes in a single configuration file -
usually app/config/routing.yml (see Routing).
However, in most applications it's common to import routes definitions from
different resources: PHP annotations in controller files, YAML, XML or PHP
files stored in some directory, etc.
This can be done by importing routing resources from the main routing file:
- YAML
- XML
- PHP
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
# app/config/routing.yml
app_file:
# loads routes from the given routing file stored in some bundle
resource: '@AcmeBundle/Resources/config/routing.yml'
app_annotations:
# loads routes from the PHP annotations of the controllers found in that directory
resource: '@AppBundle/Controller/'
type: annotation
app_directory:
# loads routes from the YAML, XML or PHP files found in that directory
resource: '../legacy/routing/'
type: directory
app_bundle:
# loads routes from the YAML, XML or PHP files found in some bundle directory
resource: '@AcmeOtherBundle/Resources/config/routing/'
type: directoryNote
When importing resources, the key (e.g. app_file) is the name of collection.
Just be sure that it's unique per file so no other lines override it.
Prefixing the URLs of Imported Routes
You can also choose to provide a "prefix" for the imported routes. For example,
to prefix all application routes with /site (e.g./site/blog/{slug}
instead of /blog/{slug}):
- Annotations
- YAML
- XML
- PHP
1 2 3 4 5 6 7 8 9
use Symfony\Component\Routing\Annotation\Route;
/**
* @Route("/site")
*/
class DefaultController
{
// ...
}The path of each route being loaded from the new routing resource will now
be prefixed with the string /site.
Prefixing the Names of Imported Routes
3.4
The feature to prefix route names was introduced in Symfony 3.4.
You also have the possibility to prefix all route names defined in a controller
class with the name attribute of the @Route annotation:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
use Symfony\Component\Routing\Annotation\Route;
/**
* @Route(name="blog_")
*/
class BlogController extends Controller
{
/**
* @Route("/blog", name="index")
*/
public function indexAction()
{
// ...
}
/**
* @Route("/blog/posts/{slug}", name="post")
*/
public function showAction(Post $post)
{
// ...
}
}In this example, the names of the routes will be blog_index and blog_post.
Adding a Host Requirement to Imported Routes
You can set the host regex on imported routes. For more information, see How to Match a Route Based on the Host.
