::find();

Argument: ($id :int)
Return: OOB Object

Example: Get item from Class, Much like ->readAction($id); But It's return object.

$book = \MyProject\Model\Book::find(5);
echo $book->title;

For Relation instead return just foreign id, Now Make it return object

class Book
{
   ...
    public function getCategory() {
        return Category::find($this->category_id);
    }
    
    public function setCategory($category_id) {
        $this->category_id = $category_id;
    }
}

And when display, You can call column from foreign key

$book = new Book();
echo $book->getCategory()->name;
