Re: Question about Signals : How to get the Primary Key Value ?

Dear All ..

 From the basic tutorial of "Polls",
I add this lines to model.py
----START--------
from django.db.models.signals import post_save

def do_something(sender, **kwargs):
     print "==========START==========="
     print "Called by : " , sender
     print "This is KWARGS :"
     print kwargs
     obj = kwargs['instance']
     print "This is instances :"
     print obj
     print "=========DONE============"

post_save.connect(do_something, sender=Poll)
---Stop--

And from the debug console while I add a new record, here is what I got :

==========START===========
Called by : <class 'poll.models.Poll'>
This is KWARGS :
{'raw': False, 'signal': <django.dispatch.dispatcher.Signal object at
0x8ddab6c>, 'instance': <Poll: WhatsUp ?>, 'created': True}
This is instances :
WhatsUp ?
=========DONE============

My question : How to het the primary key of involved object/instance
(the "id" Column in table) ?
When I try to use --> print Poll.id
It raise traceback that state (more/less) : Model 'Poll' have no object
named 'id'

Kindly please give me your enlightment

Sincerely

The instance is in, well, the `instance` argument. You get it from there.
