Could you please include the PowerPoint presentations you are using in this series in the description?

[@oauth9728]

What a detailed tutorial. THANKS. pls do Django Ecommerce, Django Multi-choice quiz series 🙏

[@veryacademy]

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 👍

[@oauth9728]

Thanks for your quick response.

Man you are a legend!

[@tounsimed5202]

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

[@veryacademy]

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

[@mdsamiulislam2522]

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?

[@veryacademy]

Hi Md - for smaller projects the ORM provides, you might start optimising further at later stages of your project with direct SQL queries

[@iopyrb]

does ORM replace the use of SQL?

[@veryacademy]

Yes for the developer, but it translates your requests into sql behind the scenes

[@iopyrb]

@@veryacademy yes, i mean.. can replace it? ( like just using orm in any project not using raw sql)

Thanks Sohail, no need for the sir though, I am not knighted ;)

Thank you once again 👍😁

[@createlifejr]

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.

[@veryacademy]

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.

[@createlifejr]

@@veryacademy Thank you.. got it! Will you be doing any courses related to caching anytime soon?

[@veryacademy]

@@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.

[@veryacademy]

Best thing is to - and I really don't mind - keep reminding me!

in fact i always hear that gjango orm is django's weak side, comparing to sql alchemy.

Yeah we had that discussion 😂

@@veryacademy thanks the playlist is really good

[@choochtrain]

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.

[@veryacademy]

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!
