Challenge #1 of 1

Q:
I can already call `$category->getProducts()` to get a collection of all of the products for a specific `Category`. But now, I want an easy way to be able to get that same collection, but filtered by newest DESC and where a product's price is greater than $100. Is that possible?

Yes: use ORM\OrderBy and ORM\WhereBy above the $products property inside Category.

Yes: add a new getExpensiveProducts() method and use the Criteria system.

Yes: add a new getExpensiveProducts() method and leverage the ->filter() method on the $this->products property.

No: it's not possible because you need a service to do this. And so, this logic can't live in your entity class.
