      railties (4.2.0), mongoid 5.0.0, ruby 2.1.1p76

      Given I have the following code

      class User
 include Mongoid::Document
 scope :author, -> { where(author: true) }
end

class Article
 include Mongoid::Document
 scope :public, -> { where(public: true) }
 scope :authored, -> {
  author_ids = User.author.pluck(:id)
  where(:author_id.in => author_ids)
 } 
end

      Article.authored.to_a is working as expected:

      {"find"=>"users", "filter"=>{"author"=>true}, "projection"=>{"_id"=>1}}
{"find"=>"articles", "filter"=>{"author_id"=>{"$in"=>[]}}}

      But
      Article.public.authored.to_a is not working properly:

      {"find"=>"articles", "filter"=>{"public"=>true, "author"=>true}, "projection"=>{"_id"=>1}}
{"find"=>"articles", "filter"=>{"public"=>true, "author_id"=>{"$in"=>[]}}}

      it turns out that 

       scope :author, -> { where(author: true) }

      is called on Article instead of User 

       {"find"=>"articles", "filter"=>{"public"=>true, "author"=>true}
