how to use helpers to conditionally include an attribute? about grape-active_model_serializers HOT 4 CLOSED

check this out: http://railscasts.com/episodes/409-active-model-serializers?view=asciicast

see how they use current_user in serializer.

So I saw that rails cast and I've tried every permutation of serialization_scope and scope and creating an attributes override method in my serializer class. None of it seems to do anything at all. Maybe I'm missing some secret step with grape+ams? This rails cast is for ams in a rails controller. Is there something special I have to do to make it work in grape?

UPDATE: So I think I figured it out. I had to do this inside my endpoint block:

desc "Get widgets"
get '/' do
  _serialization_scope = :current_application
  @widgets = Widget.all
  @widgets
end

This is less than optimal, since I'll have to constantly do this in every endpoint I define. :( But I guess it works. Would be nice if there was a more straightforward way to allow a serializer access to a grape helper.

UPDATE 2: Okay, so I can move that _serialization_scope = :current_application up to the root level of my Grape::API class, which is better.

UPDATE 3: Actually, looks like maybe I don't need that at all... just the delegate bit in the serializer. How come this didn't work earlier today? Heh. :)

cool. i am closing this issue now since you already figure it out :)
