Too Long; Didn't Read
When I was a newbie in Ruby, I would love to have a list of the most popular commands I used while I was learning Rails in a single place. I know they are not all of them, but I hope it would be most of the commands you will use at the beginning. The most common command is to create a new rails application and give it a name. The easiest way to make a change in the database is to generate the migration. Never do a change directly on your database.
