Sorry for the slightly noobish question, as I am writing my first rails app.
I get the idea of the layout view, but if you are using them, is there any way to includ
You can't if your tag is in your layout.
You may want a different layout for that controller action. Like this on the render:
render :action => "index", :layout => "some_other_layout
Also you can set a different default layout for a whole controller with this line in the controller class:
layout "some_other_layout"
Check the API docs, there's some complex things you can do with conditionals on that layout method.
