[RAILS] If you use SQLite with VSCode, use the extension (how to see the binary file of sqlite3)

I've been studying Ruby on Rails recently and use SQLite a lot.

I wanted to use the binary file **. sqlite3 ** that comes out there in VS Code, so I investigated how to do it.


Can't open sqlite3?

It came when I was doing Chapter 6 of the Rails tutorial.

Target Rails tutorial → https://railstutorial.jp/chapters/modeling_users?version=5.1

Make a model ...

$ rails generate model User name:string email:string

After applying the migration ...

$ rails db:migrate

There was a file called db / development.sqlite3.

However, this is a binary file and cannot be opened with VS Code. .. ..

Install extension SQLite

Therefore, we will introduce an extension called "SQLite".

Try installing as usual from the VScode Marketplace. スクリーンショット 2020-11-04 15.12.27.png

How to use SQLite

It's easy to use.

Open the command palette and type "sql".

(How to open the command palette) Windows:Ctrl+Shift+P Mac:Command+Shift+P

Select "SQLite: Open Database" in the search results. スクリーンショット 2020-11-04 15.17.55.png

Since it will be a file selection, select the target file (this time select db / development.sqlite3) スクリーンショット 2020-11-04 15.19.32.jpg

It looks like nothing is happening on the screen, but if you look closely at the Explorer tab, you will see an increase in the item "SQLITE EXPLORER", where each table and column is displayed. スクリーンショット 2020-11-04 15.27.13.png

Yeah, it feels like it.

If you want to see the data registered in the table, click "▶" next to each table name. スクリーンショット 2020-11-04 15.33.51.png

You could see it.

Now you can use SQLite on VS Code without opening any other tools!


Of course, even if you don't use VScode, there is a wonderful tool called DB Browser for SQLite, so you can choose which one to use.
