Hit a doozy of a bug in a rails app. Started to get some role authentication problems and having recently upgraded my app to use Rails 2.3.2 I updated the restful_authentication plugin by svn rm’ing the folder and then typing:


script/plugin install

Unfortunately that led to this error:


~/project/vendor/rails/activesupport/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant User::Authentication (NameError)
from ~/project/app/models/user.rb:4

All over the googlesphere people have experienced this issue and nobody had a solution. In desperation I re-installed the plugin but this time using git from inside the vendor/plugins folder:


git clone git://github.com/technoweenie/restful-authentication.git
restful_authentication


And it works! Wow. I hope this saves anyone else a few hours. Good luck.
