Helloo Teckiys, 

I am trying to fix the add to cart and single item remove from the cart and I am trying to fix the template to accommodate the views.py

I am trying to add the code that sends a POST request with form data to the add to cart view and single item remove from the cart but I am not getting the same error which is indicating that the order_item.variation.add(*item_var) does nothing

here is the view.py 


@login_required
def add_to_cart(request, slug):
    item = get_object_or_404(Item, slug=slug)
    order_item_qs = OrderItem.objects.filter(
        item=item,
        user=request.user,
        ordered=False
    )
    item_var = []  # item variation
    if request.method == 'POST':
        for items in request.POST:
            key = items
            val = request.POST[key]
            try:
                v = Variation.objects.get(
                    item=item,
                    category__iexact=key,
                    title__iexact=val
                )
                item_var.append(v)
            except:
                pass

        if len(item_var) > 0:
            for items in item_var:
                order_item_qs = order_item_qs.filter(
                    variation__exact=items,
                )

    if order_item_qs.exists():
        order_item = order_item_qs.first()
        order_item.quantity += 1
        order_item.save()
    else:
        order_item = OrderItem.objects.create(
            item=item,
            user=request.user,
            ordered=False
        )
        order_item.variation.add(*item_var)
        order_item.save()

    order_qs = Order.objects.filter(user=request.user, ordered=False)
    if order_qs.exists():
        order = order_qs[0]
        # check if the order item is in the order
        if not order.items.filter(item__id=order_item.id).exists():
            order.items.add(order_item)
            messages.info(request, "This item quantity was updated.")
            return redirect("core:order-summary")
    else:
        ordered_date = timezone.now()
        order = Order.objects.create(
            user=request.user, ordered_date=ordered_date)
        order.items.add(order_item)
        messages.info(request, "This item was added to cart.")
        return redirect("core:order-summary")


@login_required
def remove_single_item_from_cart(request, slug):
    item = get_object_or_404(Item, slug=slug)
    order_qs = Order.objects.filter(
        user=request.user,
        ordered=False
    )
    if order_qs.exists():
        order = order_qs[0]
        # check if the order item is in the order
        if order.items.filter(item__slug=item.slug).exists():
            order_item = OrderItem.objects.filter(
                item=item,
                user=request.user,
                ordered=False
            )[0]
            if order_item.quantity > 1:
                order_item.quantity -= 1
                order_item.save()
            else:
                order.items.remove(order_item)
            messages.info(request, "This item quantity was updated")
            return redirect("core:order-summary")
        else:
            messages.info(request, "This item was not in your cart")
            return redirect("core:product", slug=slug)
    else:
        messages.info(request, "You do not have an active order")
        return redirect("core:product", slug=slug)

here is the template which I am failing to add a form request 

        <h2> Order Summary</h2>
        <table class="table">
            <thead>
            <tr>
                <th scope="col">#</th>

                <th scope="col">Quantity</th>
                <th scope="col">Size</th> 
                <th scope="col">Total Item Price</th>
            </tr>
            </thead>
            <tbody>
            {% for order_item in object.items.all %}
            <tr>
                <th scope="row">{{ forloop.counter }}</th>
                <td>{{ order_item.item.title }}</td>
                <td>{{ order_item.item.price }}</td>
                <td>

so what we understand. removing quantity is not working as expected ? .

adding and removing items, if I added an item with a size of small, medium and large and change the quantity in the order summary template, the quantity of the very first item added to the cart is the only item affected no response from the other items with different variants that was actually changed.
