Scope is not passed through the custom attributes

[sungwoncho]

Scope is nil when serializer is called within a custom attribute of another serializer.

Contrived example:

class ApplicationController < ActionController::Base
  serialization_scope :view_context
end

class UserSerializer < ActiveModel::Serializer
  attributes :can_vote

  def can_vote
    VotePolicy.allowed?(user) if object == scope.current_user
  end
end

Above works fine. However, scope is nil when I use UserSerializer in a custom attribute of another serializer:

class CourseSerializer < ActiveModel::Serializer
  attributes :student

  def student
    UserSerializer(object.enrollment.student)
  end
end

Update

After reading the code, I realize that I can pass in scope when initializing the Serializer.

What are your thoughts on passing the scope by default, if one is defined?

@sungwoncho just checkin, are you using 0.10? from master or rc1?

Also, is there any reason you can't use belongs_to :student or some such so that it will just work? I know has_one was removed.

Propose closing since OP hasn't responded with version. (Though I correct myself, has_one was removed, but has since been re-added)

@bf4 I am using 0.9.3.I am no longer working on this project so I am not sure if upgrading the gem would have fixed the issue.

belongs_to: student as @bf4 pointed out seems the way to go for me.
IMHO passing an scope by default is unnecessary. 😄
It indeed won't work, but it seems just an edge-case for me that could be handled with the belongs_to, so I'm closing this for now.
