So Simple!, so Clear!
Thank you very much!
Two or three days reading and studying of Django documentation is finished by 15 min.

I wish you can make a part 2 or even more tutorials on this.
What if you want to use the aggregate and annotate with some conditions?
Eg. 1 - Where you want to sum the 3 most minimum of each customer. assuming each customer has made at least 3 purchases.
Eg. 2. Where you sum the purchase of each customer, excluding the purchase of a particular product or excluding the product with a specific amount.

Maybe I’ll include this topic in a Django Project tutorial which I’ll publish in the near future 😎🙌

Hi, this is a Greate tutorial, but I have question, in minute 10:07 you used this query "Customer.objects.filter(id=1).aggregate(Count('purcheses__amount))" to get the count of purchases for each customer.
why did you need to specify "purcheses__amount" in the Count function to get the purchases count, why not specified just the "purchases" only, it will count the purchases for each user.
in short, we need to count the purchases for each customer, not the purchases__amount, so is it will be more logical to put the "purchases" there not "purcheses__amount"

This is why you shouldn’t do copy & paste 🫣 you are 100% correct 🙌

I am currently building a dashboard for a side project with a django backend. I was planning on using raw sql queries and was procrastinating because of how ugly that would be. This tutorial is very timely. Thanks
