Test Model Changes in Script/Console Without Exiting

So if you’ve ever tested changes to a Ruby on Rails model in the script/console, it can be a pain having to completely quit and restart the application each time you make an adjustment. Instead you can use the reload! command

So this:

reload!

Acts as if you just did this:

exit
script/console

So not only does it require one less command, but you can still use all previously defined variables. Awesome!
