in need of help about my django ecommerce website

[Adarsh Sarda]

Hi,

I've been facing a problem recently in creating a Django Profile model for an E-commerce website.

If  a profile updates it's cart then all the carts in the admin page are getting updated with the same items.

Kindly help me out if possible. The screenshots have been attached below and the github link for the project has been provided.
