from django_weight_sort_signal.dispatcher import receiver as weight_sort_receiver

@weight_sort_receiver(order_refresh,weight=10)
def tax_order_refresh(sender,order, **kwargs):
#tax amount calculation functionality triggered on order_refresh signal dispatch
pass

@weight_sort_receiver(order_refresh,weight=20)
def discount_order_refresh(sender,order, **kwargs):
#discount amount calculation functionality triggered on order_refresh signal dispatch
pass

@weight_sort_receiver(order_refresh,weight=30)
def shipping_order_refresh(sender,order, **kwargs):

Reciever for third-party apps Eg:
In receiver callback we can give weight to sort without changing the base signal
#. receiver.py::
from django.contrib.auth.signals import user_logged_in

def do_stuff(sender, user, request, **kwargs):
#ADD SOME CODE
user_logged_in.connect(do_stuff,weight=10)

def do_stuff2(sender, user, request, **kwargs):
#ADD SOME CODE
user_logged_in.connect(do_stuff2,weight=20)

We can dispatch signal anywhere as following.
Send :
#. ::
from .signals import order_refresh

order = Order.objects.get(pk=10001)
order.status="review"
order.save()
order_refresh.send(sender=None,order=order)
