Hello,
what is the right way to handle events from livesetting ie. from an admin
interface ?
For example when as an admin I did removed order item from an order.
I did attached listener to general signal of Django model:
from django.db.models import signals as signals_models
>
> signals_models.pre_delete.connect(increase_inventory_on_orderitem_removal)
>
Because it's a very general signal I need to distinguish between
`pre_delete' sent from admin removal and from a checkout process.
Now I check this by status of an order:
def increase_inventory_on_orderitem_removal(sender, instance, *args,
> **kwargs):
> # check if object is a really an order item
> if isinstance(instance, OrderItem):
> # check if order was confirmed and can be cancelled
> if instance.order.status and \
> instance.order.status not in ('Shipped', 'Completed',
> 'Cancelled'):
>
I find it a bit hackish and doubt if it's really reliable way.
Is there some better way ?
Thanks.
