What is the Ruby on Rails' sandbox console

I started learning Ruby on Rails again.

While going through the Odin Project’s Ruby on Rails course, I came across the rails console --sandbox command and decided to explore it further. Interesting that I haven’t seen it earlier.

What does it do?

It acts as a normal console, but doesn’t persist the changes you have made, which makes it useful for testing stuff out. I will try it out.

Use it only for development, because rolling back the db transactions does not ensure you’ll end up in the initial system state
