Hi John, i am facing an issue, instead of updating the quantity (1-2-3-4) every time i click on the add-to-cart button, it just creates a new line in the console - {qty: 1} {qty: 1} {qty: 1} {qty: 1} i also tried it with the product.name and every time i got the same product name even tho i clicked on different products, please help
Hi John, enjoying your Django series. I went through the code several times and I can see when I add product to the basket it doesn't seem to update the quantity. Do you have ideas what could be the problem?
You have a typo somewhere. Put the code away for a few days and look at it again, compare it to the video then. The error will jump right out at you with a fresh pair of eyes.
Thanks John great work as always... I noticed when I "add to cart" from a product page the button does not immediately reflect the quantity unless I change to another page or refresh it... Ill review the code you went through to make sure I didn't miss something... and let you know if I flubbed LOL
just arrived at the last lesson, now I will make a Wednesday schedule :D thank you for the efforts, django started to be clearer now. I have a question, it's been a month in Python as my first language, do I need to learn JS now or postpone it?
Hello :) First I want to thank you for this tutorials, you are amazing I have one question, maybe you covered it in later videos (haven't seen them yet), after adding product to cart, cart button gets correct value but when I use browsers back button it returns me to previous page but cart button doesn't have new value. When I press refresh button (of f5) it then shows new correct value on cart button. Also when I avoid using browser back button and navigate through webpage, everything works fine. Did some googling and found out that it might be related to chased data. Tried multiple solutions (stack overflow, chatgpt...) and I am not able to force automatic page refresh after user uses browser back button. Any suggestions? or some tips what to look for?
that's just how browsers work...don't hit the back button lol why would you? If you really care, you could embed a simple browser refresh javascript tag (we have one in a future video) to your base.html file...but honestly...I don't think you need to. This is a manufactured problem that isn't actually going to affect anyone.
hey, I have a problem like when I hit the Add To Cart button on the product page, it updates the Cart qty but only shows "Cart" without the qty. If I refresh the page then It shows the "Cart"+ "qty" on the top ribbon. Is this a page refresh issue? where should I look into it?
thank your for learning such simple , i watch many time and exactly write your code but when i use add cart , just add one product to my cart ? can help me!
I followed all the steps but the button doesn't get updated automatically only if I reload the page or move to another page. Someone can help me with that ??!
I had a similar issue. Look at the line of code response = JsonResponse({'qty': cart_quantity}) and make sure the colons and spaces match exactly. In the video not only did John change the name but also the number of ": " from the previous line. It is in the views . py file in the carts folder under the def cart_add(request) section.
AMAZING lesson like always. If I may I have a qst, I watched some past playlists and you always used models instead of sessions so my qst is: is it necessary to use sessions and not create a model for carts or is it solely because of the reason it can update value without refreshing the page?
I have a quick question. I have followed the video the cart number updates however, when I change pages it goes back to zero. Do you know what the problem could be?
followed all the detail but instead of seeing the object in the console am getting the whole html page and the status response is ok what might be causing this ?
When I click on 'add to cart' on the product page, the number updates in the backend. However, in the navbar, the number disappears. When I return to the home page, the cart shows the correct number. When I visit another product page, the cart and the number are correctly displayed. But as soon as I click on 'add to cart', the number disappears again. What's happening here? Can anybody guide me, please?
update: Turns out the problem was with this line: response = JsonResponse({"qty:": cart_quantity}) I had to remove the first ':' after qty, to fix it. The right code is: response = JsonResponse({"qty": cart_quantity})
Hi John, always love your video, so easy to understand I've got a problem here in my project it's said AttributeError at /cart/add/ AttributeError: 'Cart' object has no attribute '__len__' am i missing something please can anyone help and guide me thanks

Your teaching style and method is always mind-blowing. Thanks for making us understand programming.
Glad you're enjoying it!

rewatch the video and discover what you did differently from the video.

@@namdarcs probably this one.
@@Codemycom Yup I flubbed and its working now... Couple mispells of cart_quantity and missed a . LOL Thanks JOHN!
Glad you got it sorted out!@@namdarcs

Depends entirely on your goals. No one said you ever have to learn javascript.

We will use models for logged in users to save their cart to the database, but sessions for people who aren't logged in
@@Codemycom Thank you for the clarification, your videos are amazing.
I have a quick question. I have followed the video the cart number updates however, when I change pages it goes back to zero. Do you know what the problem could be?
Not specifically...you'll have to check your code vs the video to see what typo you made.
followed all the detail but instead of seeing the object in the console am getting the whole html page and the status response is ok
what might be causing this ?
Only one cause...you didn't actually follow all the details.

Cloning is useless if you don't understand what you're doing. Rewatch the video and learn it.
Sir am getting the error while clicking on addtocart btn :The view cart.views.cart_add didn't return an HttpResponse object. It returned None instead..
You have a typo in your cart_add views.py code. Compare it to the video to discover what the typo is
nice
Thanks!
For some reason i can only add 4 products to a cart. From 0 to 4 it goes all fine and then afer trying to add another one it just stays 4.Any idea what could be wrong?
hmm i have only 4 products in database, which means i can only add 1 piece of each. is that how it should be?
@@teovukelic5046 No, you've done something wrong...i Can't guess what...you'll have to carefully compare your code to the video to see.
