bad operand type for abs(): 'str' in django
I think your are writing the code from "beginning Django E-commerce" book.
The error is in your code you write {{ cart_sutotal|currency }} in place of {{ cart_subtotal }} .
I am going through the beginning django ecommerce application for shopping cart app. I am getting the error as mentioned above while clicking the add to cart button.
I am getting the error at the line {{ cart_sutotal|currency}}
