What about a UT ?

same problem the sonata admin bundle use
```
{% render 'sonata.admin.controller.admin:getShortObjectDescriptionAction' %}
```

rewrite to
```
{% render controller('sonata.admin.controller.admin:getShortObjectDescriptionAction') %}
```
throws
```
An exception has been thrown during the rendering of a template ("Parameter "_controller" for route "_proxy" must match "[^/\.]++" ("sonata.admin.controller.admin:getShortObjectDescriptionAction" given) to generate a corresponding URL.") in "SonataAdminBundle:CRUD:edit.html.twig".
```
with the requirement fix it throws
```
An exception has been thrown during the rendering of a template ("Unable to parse the controller name "sonata".") in "SonataAdminBundle:CRUD:edit.html.twig".
```

ok, I've updated the patch. There is now a static segment (`/for`) between the controller and the format, which should fix the problem.

While thinking about this, there is another option, which might be even better: removing the need for the proxy route altogether and check for a defined path like `/_proxy`. It would remove the dependency on a Url Generator in the rendering strategy, and would not make the router proxy listener any more complex.

+1 for me the patch works i will open a PR for sonata doctrine orm bundle
```
{% render controller('sonata.admin.controller.admin:getShortObjectDescriptionAction', {},  {
    'code':     sonata_admin.field_description.associationadmin.code,
    'objectId': sonata_admin.field_description.associationadmin.id(sonata_admin.value),
    'uniqid':   sonata_admin.field_description.associationadmin.uniqid
})
```

When the proxy route is nessesary we should add a note into the upgrade guide.

+1 for less complexesy

There is one issue with removing the proxy route: when generating a proxy URL, we need a Request instance, which is not always the case. I'm going to submit another PR to "fix" that first.

I don't think removing the proxy route is good. That's the purpose of the routing system to handle generating and matching. Now if you do it manually it will probably show a bad approach to people to handle such stuff.
Also people cannot see what routes are defined explicitly and use tools like `router:debug`.

@Tobion: see #6829

I've again changed the route pattern to avoid any possible problems (even if a controller contains a `/`).

---------------------------------------------------------------------------

by Tobion at 2013-01-22T10:16:03Z

Can a controller contain `/`? It's neither a valid service nor a valid class name or?

AFAIK yes, at least I used Namespace/SubController more then once...
