Models:

class School < ActiveRecord::Base has_many :laboratories has_many :departments

deep_clone_options(:associations => [:departments, :laboratories])

def copy self.deep_clone end end

class Laboratory < ActiveRecord::Base belongs_to :school belongs_to :department

deep_clone_options(:parent_id_att => [:school_id], :equivalent_associations => [:department] ) end

class Department < ActiveRecord::Base belongs_to :school has_many :students

deep_clone_options(:parent_id_att => [:school_id], :associations => [:students]) end

class Student < ActiveRecord::Base belongs_to :department end

Migrations:

class CreateSchools < ActiveRecord::Migration def change create_table :schools do |t| t.string :name

  t.timestamps null: false
end

class CreateLaboratories < ActiveRecord::Migration def change create_table :laboratories do |t| t.string :name t.integer :department_id t.integer :school_id

  t.timestamps null: false
