With Rails 4.1 : Can't mass-assign protected attributes for ActiveRecord::SessionStore::Session: session_id, data

[rtcoms]

I am migrating my project from Rails.3.2.x to Rails 4.1

installed gem

gem 'activerecord-session_store', '~>0.0.1'
gem 'protected_attributes', '~>1.0.1'

but still getting mass assignment error. what can be the solution for this ? Should I create a custom session store class and set attribute_accessors accordingly ?

Resolved it by putting below code in config/application.rb

 ActiveRecord::SessionStore::Session.attr_accessible :data, :session_id
