How to use rails routes in grape entities?

Question

I have an image entity exposes a url to a rails controller.

The controller shows the image conforming to some business logic. (ex it deletes the image if everybody in the group viewed it,...)

  expose :media_url do |message, options|
    #TODO inject the rails route helper
  end

How could I inject the rails named route helper into the code above?

Any other hint is also welcome :)

asset_path was unknown in that context. – Boti Aug 11 '14 at 15:45
Ye, sorry that doesn't work which is a shame, but following the advice on the link should. – Stan Bondi Aug 12 '14 at 12:06
