What a detailed tutorial. THANKS.
pls do
Django Ecommerce,
Django Multi-choice quiz series 🙏
Django commerce is just big one for sure. I will promise that this will happen. I will share with you my overall big plan for the Django content on this channel - they both feature. This all just takes time at the moment. If/when/as things pick up on the channel I will dedicate more time to making bigger projects. In some respects I am only been doing this for a few months - still learning and trying to make small improvements to content and delivery style etc. I would imaging that before Christmas I would have started Ecommerce - the quiz - well that is really simple and fun one to do....😁 will see 👍
Thanks for your quick response.
You never disappoint me. Awesome tutorial. Really appreciate it.

sir Do I need to learn sql or ORM is enough for django projects ?
and I want to tell you , you are a great teacher thank you so much for your hardwork
You will be fine with the ORM up to a point when you start scaling your app to much larger audiences. At that point, depending upon the complexity of your queries, you might start to look at the SQL to optimise further
@@veryacademy thanks man
we love you sir
Thanks Sohail, no need for the sir though, I am not knighted ;)
You are the best
Thank you once again 👍😁
you have said in ur video at 9:56 minute that Queries can perform better. do u mean that direct sql query performs better than ORM?
Hi Md - for smaller projects the ORM provides, you might start optimising further at later stages of your project with direct SQL queries
does ORM replace the use of SQL?
Yes for the developer, but it translates your requests into sql behind the scenes
@@veryacademy yes, i mean.. can replace it? ( like just using orm in any project not using raw sql)
Wonderful!!!
thanks
Welcome
Please include select_Related and prefetch related.
Thank you - have added to the list
Hey Zander,
So does using, Students.objects.raw('SELECT * FROM Students"), something like that can improve performance compared to Students.objects.all()? I have seen this in SO and was kinda confused.
Evening - that is a great question. I think I can summarise this by saying ORM can be comparable in performance to using RAW queries (in most cases) (you can also bypass the ORM completely) - I will show you that shortly in the up and coming tutorials. There are times when you want to write more complex queries - so you can if you like, revert to writing your own SQL. With the ORM you are not tied to it. In your question - the query is straight forward and probably wouldn't see any real difference. What is important is - Caching - this is one of the best methods to reduce DB related performance. There are different kinds of caching implementations in Django - cached property on model - query caching and template caching. 👍 But don't get too tied up with RAW for now. If you really wanted to move down this path, learning SQL would be more worth your time.
@@veryacademy Thank you.. got it!
Will you be doing any courses related to caching anytime soon?
@@createlifejr Been asked many times - its a tricky one to teach to be honest. I have been slowly working and planning it. There is a lot of setup to this also - again a time sink. It will all click eventually and should get something out.
Best thing is to - and I really don't mind - keep reminding me!
@@veryacademy Sure! 👍
awesome
Hey Ranga, thank you. Things are real slow at the moment - for that I apologise
@@veryacademy Congratulations on 2K subscribers. More to come :)
I do find it a bit crazy to be honest!
good luck
Thanks
in fact i always hear that gjango orm is django's weak side, comparing to sql alchemy.
its pronounced 'impee''dence mismatch
Yeah we had that discussion 😂
@@veryacademy thanks the playlist is really good
No offense, but you need to fix pronunciation on this one: "Impendance" -> "Impedance"
Watching/listening I was confused, until I read the word to understand the point.
Sorry, I do that a lot, with trying to talk on the mic, thinking about what I am doing and typing I tend to make many mistakes like this. Won’t be too long until impendance day!
@@veryacademy LOL.
And thanks for the tutorial!
