Sandboxed rails console

If you want to do some changes to your models in the console but want them to be rolled back after your session, just use 
```
rails console --sandbox
```
Straight [from the docs](https://guides.rubyonrails.org/command_line.html#bin-rails-console).

It's [not a good idea](https://pawelurbanek.com/rails-mistakes-downtime) to use this in production, though.
