Unable to to generate URL from named Route in Symfony

Question

I'm getting the exception:

An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "allPrograms" as such route does not exist.").

Thing is... the route does exist:

namespace Admin\Bundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

class ProgramController extends AdminController  {
    private $config;
    private $sqlConnection;
    private $programMysqlDAO;
    ...
    /**
     * @Route("/admin/program", name="allPrograms")
     *
     * This will only trigger if there's no index.php
     * @return Response
     */
    public function indexAction()  {
        //do stuff.
    }
    ...
}

Here's the relevant portion of the twig template that calls it:

<a href="{{ path('allPrograms') }}">

I have use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; at the top of my code. I also have the routing for this particular bundle configured in routing.yml:

admin:
    resource: "@AdminBundle/Controller/"
    type:     annotation
    prefix:   /

here's what app/console debug:router shows:

  configIndex                                          ANY      ANY      ANY    /admin/config/{program}
  admin__program_create                                POST     ANY      ANY    /admin/program
  admin__program_edit                                  PUT      ANY      ANY    /admin/program
  admin__program_delete                                DELETE   ANY      ANY    /admin/program
  admin__program_index                                 ANY      ANY      ANY    /admin/program
  queue_index                                          GET      ANY      ANY    /admin/queue

As you can see, I have other named routes defined, which work properly. My router debug also shows the route in question /admin/program method:Any, but does not show the name.

I've tried: Clearing / warming the cache: php app/console cache:clear --env=prod php app/console cache:clear --env=dev php app/console cache:clear php app/console cache:warmup --env=prod --no-debug

Removing composer vendor and:
composer -vvv update

Recreating composer autoload:
composer -vvv dump-autoload -o

Does anyone have any ideas why my named route is not being found in Symfony?

UPDATE I should have mentioned, I already tried using admin__program_index in my twig template... and, yes, it does work. However, I want to use my named route and I have no idea why it's not working.

I'm using named routes in other controllers:

namespace Admin\Bundle\Controller;

use ...

class ConfigController extends AdminController  {
    /**
     * @Route("/admin/config", name="config")
     * @return Response
     */
    public function indexAction()  {
        //do stuff
    }
}

This named route works perfectly.

Answer 1

Here your route is logically for example:

admin__program_index is for request ANY /admin/program

admin__program_edit is for request PUT /admin/program

admin__program_create is for request POST /admin/program

admin__program_delete is for request DELETE /admin/program

If you can't understand you can run command:

app/console debug:router --show-controllers

This is command show routes with Controllers

Try change <a href="{{ path('allPrograms') }}"> to <a href="{{ path('admin__program_index') }}">
