Here what I build up with has many

class Book < ActiveRecord::Base
# RELATIONSHIP
belongs_to :book_manager
def customer
book_manager.customer
end
attr_accessible :book_manager_id, :description
class BookManager < ActiveRecord::Base
# RELATIONSHIP
belongs_to :customer
has_one: :book
accepts_nested_attributes_for :books, allow_destroy: :true
attr_accessible :customer_id, :visible, :books_attributes
class Customer < ActiveRecord::Base
# RELATIONSHIP
has_many :book_managers
has_many :books, :through => :book_managers
accepts_nested_attributes_for :book_managers, allow_destroy: :true
attr_accessible :admin, :first_name, :last_name, :middle_name, :email,
:email_confirmation, :password, :password_confirmation, :image,
:book_managers_attributes, :locale

I think his a correct relationship model.
