I have a database with the following tables and relationships:

Advert 1-1 Car m-1 Model m-1 Brand

If I want to retriev

Answer 1

It's in the official documentation under "Eager Loading"

Multiple relationships:

$books = Book::with('author', 'publisher')->get();

Nested relationships:

Advert::find(1)->with('Car.Model')->get();
