[RUBY] [Rails] I tried deleting the application

Introduction

I tried deleting the mini app created in the test. I will leave a memorandum in the article as well.

table of contents

  1. Procedure
  2. Delete

1. Procedure

-Delete database ・ Delete folder

I thought that to delete the app, I just had to delete the folder. However, that leaves the database behind, which can lead to glitches.

Below is an article that I have referred to. If you are interested, please refer to it as it introduces how to delete various folders other than the application.

2. Delete

Let's delete it ~

-Delete database

$ rails db:drop

Development and testing It is successful if the two databases are deleted.

・ Delete folder

$ cd ..
$ rm [app name]

You can delete it with a command, but you can also delete it by putting it in the Trash from the finder.

that's all!

Finally

I am a beginner in programming, but I am posting an article in the hope that it will help people who are similarly troubled. See you next time ~
