thank you for great tut. but when I click on a product that before added to cart it isn't add the quantity just I should change it from cart summary. how I can do that.
Hi, really cool videos! I noticed that if I try to add something to the cart, logout, and after that try to log in again to the same user, I got an empty cart.
I got same error below but I found a typeerror like : product_id: $('this').data('index'),...and I correct it : product_id: $(this).data('index'), This works. Guess I was fooling myself XD btw thank you John for doing this tutorial, now I can keep moving forward 👍
Hello sir, if we instead did it service_qty: $('#select'+ serviceid).val(), would it bring an error later on? Because with service_qty: $('#select'+ serviceid+ 'option:selected').text(), it is not working for me Thank you in advance, loving this series!
No. Code doesn't work for some people and not for you. If the code isn't working, you've done something wrong. Retrace your steps and figure out what that is...in this case, I think you left off a space before ' option:selected')
When i clicked in the quantity drop button, select the value to update and update. My dict update, and everything works, but the value in my quantity label, doesnt. Sorry if i have any mistake in my english.

Probably an error on your cart_summary.html page. The product_qty you are passing can't be turned into an int. There must be s space before option:selected -> '#select' + productid + ' option:selected' in /cart_summary.html

fortunately i read this comment. i try this tutorial in a whole day for the update button to work and find out just got messed by a single space 🥲🤣

Thank you for your very descriptive and understandable videos John! 😀
Glad you're enjoying them!
Is the same procedure for the delete button, because I can try do it by myself :D
I also add pagination, contact form and update footer.
Pretty much, slightly different...we'll do that next week.

There's likely a problem with your javascript code on the cart-summary.html page or the button HTML code itself.
There must be s space befor option:selected -> '#select' + productid + ' option:selected' in /cart_summary.html

I typed date-index instead of data-index.

I made a few mistakes in spelling quantity as quanitity between cart.py and view.py first time around. The console/terminal gives you clues :)
