I want to have a different layout for just one certain action in my Rails app. How do I do that?

You can render the partial view in the parent view using the HTML helper methods: @html. Partial() , @html. RenderPartial() , and @html. RenderAction() .
Nesting layouts is actually quite easy. It uses the content_for method to declare content for a particular named block, and then render the layout that you wish to use. So, that's the normal application layout.
By default, if you use the :plain option, the text is rendered without using the current layout. If you want Rails to put the text into the current layout, you need to add the layout: true option and use the . text. erb extension for the layout file.
# controller that calls the page
def action
render :layout => 'other'
end
layout :resolve_layout
.

.
private
def resolve_layout
case action_name
when "new"
"alternate"
else
"application"
end
end
