I've added the devise gem and an empty user model.
I've created a migration for the user model and added a has_many :orders association to the model.
I've removed the user model for now and ran rails generate devise:install. I also added a default url to config/environments/development.rb as suggested. That will need to be changed later when we're sending it to Heroku.
I ran rails generate devise user to recreate the user model with devise's additions.
I got rid of my earlier migration and added the relevant attributes to the ...devise_create_users migration instead.
I've added back the has_many association from the previous user model.
