I have a partial on main page that displays current scores of game. The  
latest scores keep coming in database. I want to update that partial  
after every 5 seconds with values from db so that latest scores will be  
displayed. How can I do that?

you can handle that from you view:

\<%= periodically\_call\_remote(:url =\> mycontroller\_path(), :method =\>  
:get, :frequency =\> 5) %\>

your controller must return the update as ajax in that case  
if you have some tag with id ‘score\_list’ it would look like

@new\_scores = ScoreList.find(…)  
render :update do |page|  
page.replace\_html “score\_list”, :partial =\> “my\_partial”, :collection  
=\> @new\_scores  
end

You probably want to have a look at periodically\_call\_remote
