Return all associated objects in collection

Question

A Company has_many :users.

A User has_many :notes.

How can I return all notes of all users in a company?

company.users.notes

Answer 1

You can set up a has_many through association between a company and note

class Company < ActiveRecord::Base
  has_many :users
  has_many :notes, through: :users
end

Then you can just use company.notes to get all notes under a single company

Answer 2

company.users.collect(&:notes).flatten
