Question

How can I generate a link from a service? I’ve injected “router” inside my service, however generated links are /view/42 instead of /app_dev.php/view/42. How can I solve this?

My code is something like this:

services.yml

services:
    myservice:
        class: My\MyBundle\MyService
        arguments: [ @router ]

MyService.php

<?php

namespace My\MyBundle;

class MyService {

    public function __construct($router) {

        // of course, the die is an example
        die($router->generate('BackoffUserBundle.Profile.edit'));
    }
}

Answer 1

So : you will need two things.

First of all, you will have to have a dependency on @router (to get generate()).

Secondly, you must set the scope of your service to “request” (I’ve missed that).
http://symfony.com/doc/current/cookbook/service_container/scopes.html

Your services.yml becomes:

services:
    myservice:
        class: My\MyBundle\MyService
        arguments: [ @router ]
        scope: request

Now you can use the @router service’s generator function !

Important note regarding Symfony 3.x: As the doc says,

The “container scopes” concept explained in this article has been
deprecated in Symfony 2.8 and it will be removed in Symfony 3.0.

Use the request_stack service (introduced in Symfony 2.4) instead of
the request service/scope and use the shared setting (introduced in
Symfony 2.8) instead of the prototype scope (read more about shared
services).
