[@rahulsaha2859]

I found this amazing channel when I was feeling low with Django and now am happy.Thanks please continue this series and also manage your playlists cause its hard to follow through them . Please also teach us about DRF

[@veryacademy]

Thanks Rahul, yeah - they are a bit of a mess that is for sure.

[@AcademyOmen]

Amazing 🔥✅ This is the only channel with such videos on django👏

[@veryacademy]

It won’t stop, at some point I will refine all of this into a coherent course 👍

[@julienboudreau8419]

Just joined your channel based on this tutorial. I've been learning Django from mostly your channel. Would love to see more in depth applications of model inheritance, database optimization, etc. Currently following your django ecommerce course.

[@veryacademy]

Thanks Julien, noted. It is a popular request, particularly the optimization. We will get there, these types of tutorials - in my opinion need a better base to start from, this is what the ecommerce project will provide eventually.

[@julienboudreau8419]

@@veryacademy Thanks that sounds great. Your tutorials are the only ones that get in depth with real world examples and look at some of the deeper django features, so I've been learning lots. I'm following your ecommerce project now looking forward to completing. On the side, I'm building my own app with lessons learned. I can see the ecommerce being an actual course. Keep it up love all the content.

Wow bro thanks you so much

[@veryacademy]

Any time

[@bellosegun]

I prefer the multi-table Inheritance... Looks simpler and more readable..

[@alkfalfnsflgjslfj2127]

Can you do a video on advanced user authentication worthy of production plz

[@veryacademy]

If or when the community grows I will continue providing more advanced and in depth tutorials.

[@ThukuWakogi]

Hi Would a json field work in this scenario? And what are the benefits and disadvantages

[@veryacademy]

Hi Tim, yes you could use something like a JSONB in Postgres. Maybe it’s better to think about Tradeoffs initially, for example could you easily get Django admin to save multiple inputs to a JSONB? Once you have suitably indexed, cached and otherwise optimised - unless you are running big datasets it probably just bakes down to - do you want to go that extra effort to learning how to work with this data in your chosen db - assuming we are talking about Postgres / MySQL. You will see lots of info online, negative and positive, always take with a pinch of salt.

[@bringinglife2]

Hello, I have a doubt, which is more efficient between the two, products= Product.objects.all(), products_ = products.filter(something=something) or Product.objects.filter(something=something) while quering? like in terms of the number of queries in db. Thanks :)

[@veryacademy]

I get the sentiment of your question. Both queries need to run through the whole table to find the data - so it would take in terms of time - probably be the same. Also the amount of queries should be the same.
