[Django] Cart summary template optimization

Cart (6)

/ Optimization / 얕은복사 / 깊은복사

최적화

• 얕은복사 -> 깊은복사

Cart.py

class Cart():
    def __iter__(self):
        all_product_id = self.cart.keys()
        products = Product.objects.filter(id__in=all_product_id)
        import copy
        cart = copy.deepcopy(self.cart)
        for product in products:
            cart[str(product.id)]['product'] = product
        for item in cart.values():
            item['price'] = int(item['price'])
            item['total'] = item['price'] * item['qty']
            yield item

• 완전복제를 위해서 cart = self.cart.copy() 가 아닌 copy.deepcopy 를 이용해서 객체를 복사해준다.
