I’m going to continue poking at rails – it’s very exciting 🙂 However, I’m a bit concerned about the warnings about obsolete gems usage. How can I update rails? Googling indicates to re-install all gems, or grep for old code and manually replace. Is there a single command to do that? thufir@arrakis ~/rubyCode $ thufir@arrakis ~/rubyCode $ rails dummy create create app/controllers create app/helpers create app/models create app/views/layouts create config/environments create components create db create doc create lib create lib/tasks create log create public/images create public/javascripts create public/stylesheets create script/performance create script/process create test/fixtures create test/functional create test/integration create test/mocks/development create test/mocks/test create test/unit create vendor create vendor/plugins create tmp/sessions create tmp/sockets create tmp/cache create Rakefile create README create app/controllers/application.rb create app/helpers/application\_helper.rb create test/test\_helper.rb create config/database.yml create config/routes.rb create public/.htaccess create config/boot.rb create config/environment.rb create config/environments/production.rb create config/environments/development.rb create config/environments/test.rb create script/about create script/breakpointer create script/console create script/destroy create script/generate create script/performance/benchmarker create script/performance/profiler create script/process/reaper create script/process/spawner create script/runner create script/server create script/plugin create public/dispatch.rb create public/dispatch.cgi create public/dispatch.fcgi create public/404.html create public/500.html create public/index.html create public/favicon.ico create public/robots.txt create public/images/rails.png create public/javascripts/prototype.js create public/javascripts/effects.js create public/javascripts/dragdrop.js create public/javascripts/controls.js create public/javascripts/application.js create doc/README\_FOR\_APP create log/server.log create log/production.log create log/development.log create log/test.log thufir@arrakis ~/rubyCode $ thufir@arrakis ~/rubyCode $ ruby /home/thufir/rubyCode/dummy/script/ generate /home/thufir/rubyCode/dummy/script/…/config/boot.rb:28:Warning: require\_gem is obsolete.
