You will learn about the differences between select_related and prefetch_related, when to use each of them, and how to apply them in real-world scenarios. By the end of the tutorial, you will have a solid understanding of select_related and prefetch_related and how to use them to optimize your Django queries

Hi Guys 1) hope you enjoyed the video, I did my best to explain these concepts but the renovation 3 floors below didn't help. Sorry if you hear some noises in the background (did my best to mute them). 2) The 4th part of the django and React native tutorial will be published next week 3) Have a lovely weekend 😉

How did YouTube know I was searching for this kind of video? I remember I wrote a comment somewhere that I need a video like this, just a day after I see this video? Wow.

This is very insightful and helpful, I wasn't aware of all the background queries being made without optimizing them. We need more optimization videos for Django.
