I will admit: this course was rewritten three times before publishing. At first, I planned it to be longer, covering roles/permissions in other Laravel-related systems.
But then I realized we had already covered those in other courses, so I decided not to duplicate those lessons here.
Here are the links:
Also, I like this course because it covers the main things you need to know without spending long hours repeating the same things. But if you feel that some cases of roles/permissions are not covered in this course, feel free to add comments, and I may add them in the future.
