each_full

Yields each full error message added. So Person.errors.add("first_name", "can't be empty") will be returned through iteration as "First name can’t be empty".

  class Company < ActiveRecord::Base
    validates_presence_of :name, :address, :email
    validates_length_of :name, :in => 5..30
  end

  company = Company.create(:address => '123 First St.')
  company.errors.each_full{|msg| puts msg }
  # => Name is too short (minimum is 5 characters)
  #    Name can't be blank
  #    Address can't be blank
