I will output to myself only within the range of my memory!

①

Terminal


rails _6.0.0_ new test -d mysql

②

Terminal


rails db:create

③

Terminal


rails g model test

④

db/migrate/2020 ・ ・ ・ ・ ・


t.string :name, null: false　(The description on the line here is appropriate)

⑤

Terminal


rails db:migrate

⑥

config/routes.rb


root to tests#index (The line here is also appropriate)

⑦

Terminal

I wrote everything up to this point in my memory. I think there are some things that are missing or wrong, but if there are any mistakes, I can tell by looking at the error, so please do not believe 100% if you refer to this!

That's all from the scene!
