This is the deck for a https://www.rubyfuza.org 2019 talk by Stefan Wintermeyer about the three frameworks Ruby on Rails, Phoenix Framework and Hanami.

Download https://raw.githubusercontent.com/rails/rails/master/ activerecord/lib/rails/generators/active_record/ model/templates/model.rb.tt and copy it to lib/templates/active_record/model/model.rb.tt It will be used for every "rails g model xyz" or "rails g scaffold xyz".
