you can create 2 method in user model activating & deactivating user

class user < activerecord::base   def activate_account!    update_attribute :is_active, true  end   def deactivate_account!    update_attribute :is_active, false  end end 

as type of is_active column boolean, can use user.is_active? method generated rails check if user's account active or not
