I can feel a great understanding of Django from your end. I always look for your videos first for any concept. Perfectly understood, thanks 👍👍

What is the difference between following. Why should I use annotate
print(Sale.objects.annotate(profit=F('income')-F('expense')).values('profit'))
print(Sale.objects.values(profit=F('income')-F('expense')))
Most importantly, Sir you are doing a Gr8 work.

The videos are quite clear in terms of the functionality you are trying to present, but I think sometimes we dont have that much of experience with SQL, so you should not comment the connection.queries print statement, because we want to see how each query runs.
We could also do it while practicing, but it would be great if you could keep it enabled for most of the time, in case we want to see what is happening behind the scenes.

[@bugbytes3923]

Thanks for the suggestion! I'll keep that in mind for future ORM videos.

When running prefetch and select related, how do we get back products.promo.price rather than products__promo__price? The first method allows me to reuse templates rather than having to go into templates and add the dunder to every occurrence
