[Answer]-Django objects filter hurge array of integers

Maybe there is a better way for that, but this one should work:

order_nrs = range(123460000, 123461500)
list = Order.objects.filter(order_number__lt=max(order_nrs), order_number__gt=min(order_nrs))

Or

list = Order.objects.filter(order_number__range=order_nrs)
