Timers in Ruby/Rails, any ready-made solutions?

Question

Ruby on Rails

It is necessary to refresh the page after a certain period of time, which depends on the value in the database.
Are there ready-made timers (gems) that can handle this task?

Answer 1

controller

class MyController < ApplicationController
  def show
    @timer = 50; # for example
    render :show
  end
end

view

<meta http-equiv="Refresh" content="<%= @timer %>">

Answer 2

Yes, the GON gem has a watch method to just pull the value at the right frequency - https://github.com/gazay/gon
