Q: 

Ruby on Rails-UML Question

I am trying to use yUMLmeRails and Railroad on my Rails app to generate UML.

cd myapp

rake yUMLmeRails:download

I get error as: Error loading model classes. Are you at your apps root dir? Rake aborted No such file to load

I am at my app's root dir. It generates a .png file in the diagrams folder. But when I open it it says 'Could not load the image'

Any suggestions will be useful.

Thanks
