I have followed this really helpful tutorial:
http://blog.willj.net/2011/05/31/setting-up-postgresql-for-ruby-on-rails-development-on-os-x/
I would really like to run rails new myapp
and have the postgres db set up automatically. Is there any way I can do that using a Rails application template or something similar?
On a unix based system:
sudo -u postgres createuser -d -R -P APPNAME
sudo -u postgres createdb -O APPNAME APPNAME
You can create a script and put it somewhere in your $PATH if you can't remember.
