railstutorial.org is a good free to use online tutorial. Forget about
your current project and work right through the tutorial to get the
hang of what it is all about. railsforzombies.org looks fun but I
have not tried it.
Also see the Rails Guides.
seeds.rb is just a file that is executed when you run rake db:seed.
