Problem

Track.last.authors => works
Track.last.original_author => doesn't work

User.last.creations => works
User.last.original_creations => doesn't work.


I'm still a beginner and not entirely sure how the relationships work, and which words need to match. For example, does "author" need to match in "belongs_to :author" from Track_Author with "has_many :authors" from Track.rb?

Track.rb

  #belongs to multiple authors
  has_many :track_authors
  has_many :authors, through: :track_authors
  has_one :original_author, through: :track_authors, conditions: { track_authors: { author: true } }

  #bookmarked users
  has_many :track_users
  has_many :users, :through => :track_users 

Track_author.rb

class TrackAuthor < ActiveRecord::Base
  
  belongs_to :author, class_name: 'User', :foreign_key => "user_id"
  belongs_to :creation, class_name: 'Track', :foreign_key => "track_id"

end

User.rb

  #authors track
  has_many :track_authors
  has_many :creations, through: :track_authors
  has_many :original_creations, through: :track_authors, conditions: { track_authors: { author: true } }
  
  #bookmarks track
  has_many :track_users
  has_many :tracks, :through => :track_users 

Temporarily solved by doing

 #track.rb
 def author
   track_authors.where(:author => true).first.author
 end
