hi ,
In models.py i have
class Customer(...)
bill_no=models.CharFeild(...)
All i need to access the field 'bill_no' and assign a value, In
views.py i wrote
from django.db.models.signals import post_save
from mypro.myapp import Customer
def after_save(sender,instance,created,**kaw):
sender.bill_no='INV'+ str(sender.id)
post_save.connect(after_save,sender=Customer)
i'm getting an exception as attribute bill_no and id is not found ,so
i checked the db tables ,they are present, I suppose i misunderstood
the concept .Please help me to find the fault
