[RUBY] Change DB from SQLite to MySQL


After making a model, migrating, and checking the DB with Sequel Pro

I don't have the database I intended to create! Since it became, I will post the remedy as a memorandum.


After dealing with it by referring to the article of here, the solution was reached.

What i did

Modify gemfile

This is a rudimentary mistake, but comment out the selected part of the image below (SQLite3 in the gemfile). スクリーンショット 2020-10-12 6.06.03.png

At the terminal

bundle install --without production

Because I need to make a DB

bundle exec rake db:create

And was this necessary? Maybe it wasn't necessary because I was already doing it

rails db:migrate

did it

You can now check the database on Sequel Pro. スクリーンショット 2020-10-12 6.18.21.png
