## method in my User model -this works but would like to refactor to more elegant block if possible

  def self.find_next_user_by_role(role)
    @last_set_user_id = Client.last.user_id || 0
    @users = Role.find_by_name(role).users
    user_id = @users.first.id
    @users.each_with_index do |user,index|
      if user.id == @last_set_user_id
        if @users[index] == @users.last
          user_id = @users.first.id
        else
          user_id = @users[index+1].id
        end
      end
    end
    return user_id
  end
