I am creating a Ruby on Rails application where data from an online database is pulled and stored in my local database. However, this process only happens every time I re-load the page.

Moreover, I would like to create something (maybe a timeout), that would allow me to run the code every amount of time (2 minutes for example). I do not know how to do that.

Thank you.

What I have tried:

I do not know where to start, thus I have tried anything yet.

I used this:

def show
  every_n_seconds (120) do
     #code to do
 end
end

And all the way at the top, (so that ruby sees that method before anything else), I have:

def every_n_seconds(n)
    loop do
      before = Time.now
      yield
      interval = n-(Time.now-before)
      sleep(interval) if interval > 0
    end
  end

It is working quite nice. Thanks everyone anyway. I hope this can help someone in the future.
