NEWBIE: replace_html not working as I expected HELP!!!

I was hoping the following code would generate a new turing everytime it was click. But it renders everything the first time the page is rendered and replaces the image once.. but also has already set to session[turing] to the last call to createturing.. so the first image and session[turing] don;t match!!! I thought moving to a partial would hold off the execution of the partial until the link was clicked... guess not!!!

how should i implement this?

<div id="turing"><%= render(:partial => "createturing" ) %></div> <%= link_to_function 'refresh' do |page|   page.replace_html 'turing', render(:partial => 'createturing') end %>

No as you found out, this is all evaluated in one go (How could it be otherwise since rendering the partial can only happen serverside?)

You can use link_to_remote to make an ajax call.
