```
* Now you can alos use field access to provide OrderActions to `order_by()`
* Order ascending:
* OLD: `Product.objects.order_by("name").all()`
* NEW: `Product.objects.order_by(Product.name.asc()).all()`
* Order descending:
* OLD: `Product.objects.order_by("-name").all()`
* NEW: `Product.objects.order_by(Product.name.desc()).all()`
* You can of course also combine different models and many order_bys:
`Product.objects.order_by([Product.category.name.asc(), Product.name.desc()]).all()`
