I tried deleting the mini app created in the test. I will leave a memorandum in the article as well.
-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.
Let's delete it ~
$ 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.
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 ~
