Generating UUID and ApiTokens for Laravel Eloquent Models using Observers

Recently I needed to replace Eloquent's default auto-increment numeric ID with a UUID on a few of my models. This can be done in several ways, but after a good chat with the great people in the #Laravel channel on PHPNL's Slack team, I decided to use Laravel's Observers. Also, I needed to generate API Tokens for certain models, so why not use the same solution.

This is an example repository.
