  Here's a patch that proves that it is broken.

  • inflector_failing_test.diff 1.2 KB

  • State changed from “new” to “wontfix”

  This appears to be 'just how it is' with ruby unfortunately:

  >> Gamma.const_get("Beta")
  => Alpha::Beta
  >> Gamma.const_defined?("Beta")
  => false
  

  We check const_defined? before calling const_get and ruby returns false here. This is a ruby bug / feature and should probably be fixed upstream.

  If you get a work around from upstream, we'd be happy to use it here.

  @nzkoz

  Indeed, it's already fixed in Ruby 1.9

  % cat const_defined.rb
  class Alpha
    class Beta; end
  end
  
  class Gamma < Alpha
  end
  
  puts Gamma::const_get('Alpha')
  
  puts Gamma::const_defined?('Alpha')
  

  % ruby18 const_defined.rb
  Alpha
  false
  
  % ruby19 const_defined.rb
  Alpha
  true
  

  I'm gonna ask Ruby 1.8.x maintainers whether this could be backported to 1.8 on not.
