Use the Stock object as initial value, so not queryset.item_name, but queryset (although since it is not a queryset, it is better to rename this to stock):

from django.shortcuts import get_object_or_404

def create_order(request, pk):
    stock = get_object_or_404(Stock, id=pk)
    if request.method == 'POST':
        form = CreateOrderForm(request.POST, initial={'order_item': stock})
        if form.is_valid():
            form.save()
    else:
        form = CreateOrderForm(initial={'order_item': stock})
    context = {
        'form':form
    }
    return render(request, 'add_items.html', context)

Note: It is often better to use get_object_or_404(…) [Django-doc],
then to use .get(…) [Django-doc] directly. In case the object does not exists,
for example because the user altered the URL themselves, the get_object_or_404(…) will result in returning a HTTP 404 Not Found response, whereas using
.get(…) will result in a HTTP 500 Server Error.
