Question

I have a Rails Builder template:

# in app/views/foos/index.xml.builder:
xml.Module do |mod|
  ...
  mod.Content :type => 'url',
          :href => foos_url(:bar => 'baz',
                            :yoo => 'hoo')
end

(It creates the XML for an OpenSocial Module file, but that’s not important.)

The problem is that the rendered XML looks like this:

<Module>
  ...
  <Content type="url" href="http://myapp.com/foos?bar=baz&amp;amp;yoo=hoo"/>
</Module>

That URL suffix should be “bar=baz&yoo=hoo.” How do I keep Builder from escaping the amerpsand?

Later

Perhaps the URL suffix should be “bar=baz&yoo=hoo” in the source for XML-validity rules, but certainly it shouldn’t be double-escaped, should it?

Answer 1

I know I’m late here – but for anyone coming in from google (like me) the trick is to add an :escape => false to the url_for – that way the url only gets escaped once.
