Question

I have a Symfony2 project and I would like to be able to create routes on the fly. For example, I have a database conected with the project and for each element from a specific table, I would like to create a route like main/help/$help_id.

I can’t find a tutorial on how to do it.

You definitely do not need dynamic routes for that.

my_route:
    pattern: /main/help/{help_id}
    defaults: { _controller: MyBundle:Help:show }

Then, in your controller action:

class HelpController
{
    public function show($help_id)
    {
        // Find your help item in the database.

        if ($help_item) {
            // Display your help item.
        } else {
            throw new NotFoundHttpException('The help item you requested was not found');
        }
    }
}
