ActiveSupport::CurrentAttributes provides a thread-isolated attributes singleton, perfect for request-specific data like current user, role, or locale.
create a current.rb in models directory and add the attributes we want to set

class Current < ActiveSupport::CurrentAttributes
  attribute :role
end

then in application controller we can set it like this

class ApplicationController < ActionController::Base  
  before_action :set_current_attributes

  def set_current_attributes
    Current.role = session[:role]
    // ... other attributes
  end
end

now in your application we can directly access and use like Current.role
