Templates we use, to build Rails projects at Steven H. Allen & Co. (http://stevenhallen.com)
The problem we want to solve:
We set up projects roughly the same for every rails app, so we want to automate that as cleanly as possible. The improved Rails 3 templates have made it a lot easier to create and maintain rails app generation templates
This template, at the moment, sets up the Rails application using PostreSQL
Create a directory to store all of your rails projects:
$ mkdir ~/dev
Then enter that directory and generate a new rails app
$ cd ~/dev
$ rails new <rails_app_name> -m https://github.com/stevenhallen/rails_3_templates/raw/master/base.rb -S -T -d postgresql
