what's the easiest way to setup a ruby/rails sandbox locally?

Question

I like to play with dynamic programming languages before I get confident regarding their dynamic behaviors. While there are online ruby sandbox sources available, I prefer to test it out locally.

In javascript a html file with script tag is sufficient to write any sample javascript code.

What's the equivalent of forming this sandbox for ruby with...?

1. a boilerplate
2. manually setting up ruby sandbox (prefered)

Answer 1

If you just want a ruby sandbox $ irb will do the trick.

If you want a ruby on rails sand box $ rails c -s short for $ rails console ––sandbox.

This command loads our Rails application, connects to the database and automatically starts a database transaction. All database operations performed within this console session are rolled back upon leaving the console.
