Question

How can I remove the layout application.html.erb from rendering on a particular page. It is now visible on all pages in my application.

Answer 1

You can override default rendering at the controller level.

class Admin::HomeController < Admin::BaseController
  layout "admin"

You can also override rendering of layouts at a controller action level:

def show
  render :layout => "layout_for_show_only"
end

And, if you are really desperate, you can override layouts in the view:

<%= render "print_view", :layout => "print" %>

See the excellent rails guide on the subject: layouts and rendering in Rails
