I’m looking for an extension (gem, plugin, whatever) that inserts  
comments like

... around rendered templates (except in production env). A cursory search didn't bring up anything, but I may have chosen the wrong terms. It doesn't have to work for arbitrary template engines, ERB is enough. Michael -- Michael S. mailto:removed\_email\_address@domain.invalid http://www.schuerig.de/michael/

Tattler doesn’t work with Rails 3 anymore. This little bit of code,  
inspired by it, does.

unless Rails.env.production?  
class ActionView::Template  
def render\_with\_comment(\*args, &block)  
render\_result = render\_without\_comment(\*args, &block)  
if mime\_type.nil? || mime\_type === [Mime::HTML, Mime::XML]  
(“\n” +  
render\_result +  
“\n”  
).html\_safe  
else  
render\_result  
end  
end  
alias\_method\_chain :render, :comment  
end  
end
