Help required on IFrames - Ruby on rails

Hi, i’m using a IFrame to dynamically load a part of my webpage. When i use <%= link_to> tag i’m unable to set the target so that the source reference provided in ‘link_to’ tag opens in IFrame. Is there a way to overcome this issue.? Also,Instead of using IFrames,is there any other options in rails to form the templates.

thanks FF

<%= link_to ‘name’, {:action=>‘new’}, :target=>‘_blank’ %>
