I have more experiences on django. Recently I looked into ruby on rails and I don't want to look back. * bundle install. In ruby everything is a gem when you deploy to a new machine all you need to do is "bundle install". In django I really don't see a comparable facility. I recall I forgot something until I got an "import module error" * scaffold. ruby on rails scaffold just makes development usper fast. * dev/test/production config. Well it is just very convenient. * db migration. migration make db update/change much easier. Changing db/data schema is so painful in django.
