This is how I create a new Rails app

newrails

Start with
$ rails new some_app -d postgresql

Next I go to
./config/application.rb
and add the following

config.generators.stylesheets = false
config.generators.javascripts = false
config.generators.helper      = false

Now my folders won't be filled with files I'm not going to use.


After that I initialize git and add 

config/secrets.yml

to my .gitignore file.
