Ensures Immutability Of

There are many cases where a model attribute should not be changed once it’s set. This plugin makes it dead simple.

Example

class Account < ActiveRecord::Base ensures_immutability_of :username, :email end

account = Account.create(:username => ‘jgreen’) ... account.update(:username => ‘jgreen’) # raises RuntimeError
