By default Rails will assume that req may contain malicious text (such as some evil js for example) and will escape it so that the raw html appears on the page. Since you know that req is safe to output directly you can either use <%= req.html_safe %> or <%= req = "<span .... >".html_safe %> On a separate point I would use a view helper method rather than defining req inline however.
