Question

I’m transferring a Ruby app I once made into Rails.
Now the app does some calculations that take a while (up to infinity (in theory) if you like :p).
To show a user the status of everything, I previously used the console. Now, obviously, I want my browser to show this.

Does anyone has any pointers where to start reading/exmples/gems/ideas?
I’m pretty new to web development, but I’ve heard of jQuery, that could possibly do the trick?

Answer 1

As per my understanding you have two options to do this

1 – using some kind of a server push method to be implemented. You may use following components

juggernaut (http://juggernaut.rubyforge.org/ )
http://www.ape-project.org/

2 – Using PeriodicalUpdater with JQuery. This will send a request to the server in a given time interval.

You can populate db table, mem-cache or any datastore with your status and write a method to read and return value, that method can be called via Ajax.PeriodicalUpdater

I have done this, but this is killing the performance as it request the server (in mycase it was every 5 seconds)

Even though I personally haven’t done, I prefer the server-push option is the methodical way to go

HTH
