Symfony2 how to allow slug with dashes in routes regex?

Question

My route (slug contains dashes!):

region:
  pattern: /regione/{slug}-{id}
  defaults: { _controller: SWAItaliaInCifreBundle:Default:region }

<

Answer 1

Slashes are by default forbidden. You can enable them by changing the default requirements. In your case it'd be also good to give requirements for the id as it's separated with dash.

See example below.

region:
    pattern: /regione/{slug}-{id}
    defaults:
        _controller: SWAItaliaInCifreBundle:Default:region
    requirements:
        slug: "[a-zA-Z1-9\-_\/]+"
        id: "\d+"

Answer 2

This regex works for me. ({id} requirement suggested by Michael)

region:
  pattern: /regione/{slug}-{id}
  defaults: { _controller: SWAItaliaInCifreBundle:Default:region }
  requirements:
    slug: "[a-zA-Z0-9-_/]+"
    id: "\d+"

Answer 3

if you try this it will throw a error like this:

An exception has been thrown during the rendering of a template ("Parameter "slug" for route "routing_whatever" must match "[a-zA-Z0-9-_/]+" ("Topics/Virtualization Security" given).") in ...

as viewed in http://symfony.com/doc/current/cookbook/routing/slash_in_parameter.html you must use:

slug: ".+"
