Question

Is it possible to nest layouts in Rails 3.2? I’d like to create a generic layout used by application.html.erb and allow a couple views in the application to use it. I found the Nested Layouts ruby gem, but it hasn’t been updated in four years. It would be awesome if I could do something like the following in my application.html.erb file:

<% inside_layout 'html5_boilerplate' do %>
  <div id="container">
    <%= yield %>
  </div>
<% end %>

I found an easy solution in this blog post.

In my ApplicationHelper, I added the following:

def parent_layout(layout)
  @view_flow.set(:layout, output_buffer)
  self.output_buffer = render(:file => "layouts/#{layout}")
end

In application.html.erb, I added:

<% parent_layout 'html5_boilerplate' %>
