Hi guys! I am having a problem using railroad gem while running the command: railroad -C | neato -Tpng > controllers.png

i get this error: c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/active_support/ dependenci es.rb:445:in `load_missing_constant': uninitialized constant AdminSessionsContro ller (NameError)         from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_suppo rt/dependencies.rb:77:in `const_missing'         from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_suppo rt/dependencies.rb:89:in `const_missing'         from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_suppo rt/inflector.rb:352:in `constantize'         from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_suppo rt/inflector.rb:351:in `each'         from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_suppo rt/inflector.rb:351:in `constantize'         from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_suppo rt/core_ext/string/inflections.rb:162:in `constantize'         from c:/ruby/lib/ruby/gems/1.8/gems/railroad-0.5.0/lib/ railroad/controll ers_diagram.rb:28:in `generate'         from c:/ruby/lib/ruby/gems/1.8/gems/railroad-0.5.0/lib/ railroad/controll ers_diagram.rb:24:in `each'         from c:/ruby/lib/ruby/gems/1.8/gems/railroad-0.5.0/lib/ railroad/controll ers_diagram.rb:24:in `generate'         from c:/ruby/lib/ruby/gems/1.8/gems/railroad-0.5.0/bin/ railroad:47         from c:/ruby/bin/railroad:19:in `load'         from c:/ruby/bin/railroad:19

Any suggestions how to solve this??? Thanx in advance Kostas L.

Here is a hack of a fix I found: http://d.hatena.ne.jp/zenpou/20081021/1224559643

There is certainly a more elegant way to do this, but it got the job done when I needed to make some models right quick.

To summarize, from the link, in lib/railroad/app_diagram.rb

make the following change:

< File.basename(filename).chomp(".rb").camelize
