Help required on IFrames - Ruby on rails

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.


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