I want to create a news ticker. I pull the top five articles from the  
database in my controller and pass it on to my view. I have a ticker  
bar, and I want to cycle through each article continuously. I  
previously did this with custom javascript from an RSS feed.

Any ideas?

Thanks.

It’s expensive, but periodically\_call\_remote will issue an Ajax call  
to your server at a specified interval and you can then update a div  
containing your news blip.

I’m familiar with the commands, it’s implementing them that’s causing  
me headaches. When I try using

\<%= periodically\_call\_remote(:update =\> ‘ticker\_headline’, :frequency  
=\> 3, :url =\> { :partial =\> ‘article’, :collection =\> @articles }) %\>

in or outside of my tag, it loads the entire home page over again and  
puts it inside. NOT the article title I want…

What about passing the @articles collection to cycle? Anyway to use  
that with JavaScript to accomplish the same thing without the expense  
of periodically\_call\_remote?

Are you rendering with

:layout =\> false

in your callback function?

What about using custom JavaScript and passing the articles  
(@articles) to that JavaScript from the controller?
