Tips and tricks

• Add redirection in environment.rb
• Database tables in pluralis (e.g. people)
• scaffolding models in singularis (e.g. Person)
• Add default controller/action in config/routes.rb
• gem update --system - to update gem system. Solved my rails 1.2.3 problem! If that also fails try to install gem manually.
• Make sure that dispatch.fcgi have the right execution permissions. Dont use zip to move applications!
• Install WindowsInstikiInstall
• If rails 2.2.2 or later is used the MacOSMySQLGem must be installed.
