Question

stack trace is not showing like it should (in the browser). Instead I get public/500.html rendered. The problem seems to be recreated when I created a new rails project and apply the haml plugin. Originally I though it was this ruby script causing the problem:

class ToHaml
  def initialize(path)
    @path = path
  end

  def convert!
    Dir["#{@path}/**/*.erb"].each do |file|
    `html2haml -rx #{file} #{file.gsub(/\.erb$/, '.haml')}`
    `rm #{file}`
    end
  end
end

path = File.join(File.dirname(__FILE__), 'app', 'views')
ToHaml.new(path).convert!

I though it might have deleted an erb template used to show the stack trace. That doesn’t appear to be the case because I can’t find any template for that in app/views.

So it must be the haml plugin which is causing the problem

haml --rails MyRubyApp

Not sure how, but after I run this stack traces no longer display in the browser (just the 500.html). I’ve tried explicitly launching the server in development mode without any effect.

Anybody have insight on this? Thanks in advance.

The solution was to download an http sniffer and have a look at the post data. turns out there was a syntactic problem (although valid) in some of my view code (a pair of “[]” appended to a string which shouldn’t have been there).

Hope this helps anyone experiencing the same kind of issue.
