I am learning Python by building a simple e-commerce store using Django. I've been following this tutorial for guidance [this video] . When I pass an order on the site (on localhost), the order is registered 2 times in the backend. Ie: Order #1, Order #2 in the admin panel. I am wondering how I can merge both so 1 order passed on the site = 1 order on the dashboard? In order 1, the field complete is set to True and the Transaction is filled. [LINK] In order #2, the Pickup time & Type are both set.
