Question

How do I use layouts with XML in Ruby on Rails? When using HTML a file application.html.erb with a <%= yield %> is enough, but that didn’t work for XML. A file named application.xml.builder gets executed, but the yield doesn’t work (without <%= %> of course). What is the way to do this?

Answer 1

You need to append the result of the yield to output being produced. Here’s an example application.xml.builder that demonstrates this technique:

xml.header do
  xml << yield
end
