Auto Refresh a page in Rails 3
How to periodically auto refresh page with paramaters in Rails 3开发者_JS百科?
Place the following HTML within the <head> of the applicable views. This should not be used when the page had POST parameters sent, only GET parameters. Change the 5 to the interval, in seconds, you want the page to refresh at.
<meta http-equiv="refresh" content="5" />
Though this works, I'd recommend considering using AJAX to refresh only the needed content which will not only be faster but less jolting to the user and will have a lower impact on your server's load.
This is not specific to Rails and applies to any webpage. Since Rails is server-side, and the server cannot control the browser, Rails has no control over page refreshing.
A completely different and more modern approach is to use a service such as PusherApp. It will open a socket to the Pusher server in Javascript and listen for events that should generate changes on your page.
