title: Update content when new values are added to database?
body: <p>I know my question might be ovbious for some of you, but I'm not sure how to do it, and I can't find it on google, probably because I'm not using the right keywords.
  I'm using the latest rails. On my view I have a table generated by rails. People are able to add content to that table by sending a rails form. 
  I want this table to be updated with newly updated values, without having to refresh the page.
  For example, if user 1 sent the rails form and added a new value to the database, I want user 2 to see this update without having to refresh the page.</p>
