Using rails3 and just installed haml and ran haml --rails myapp I get "undefined method `html_safe' for nil:NilClass"
Error when trying to access form_for @user The rails error is quite uninteresting and can be seen here: http://pastie.org/874602 I added class NilClass def html_safe Rails.logger.info caller.pretty_inspect end end To get some more useful information, and below is the result. I'm a haml noob and I don't know what to make of this. All other pages I have render just fine Rendered users/_form.erb (2.0ms) ["/Users/daniel/.rvm/gems/ruby-1.9.1-p378/gems/haml-2.2.21/lib/haml/ util.rb:216:in `html_safe'",
