Ever happened to forget what columns does a Model has?
well, instead of Model.column_names, you can easily install the annotate_models plugin which adds the models schema info as a comment at the top of your model.rb file.
install from
script/plugin install http://repo.pragprog.com/svn/Public/plugins/annotate_models
and from the project root
rake annotate_models
