Hi,
Am rather new to django and this error makes no sense to me..
Traceback (most recent call last):

Rather what i don't understand is why django is trying to int casting
the string... find attached the models.py file and the script am
running in python manage.py shell.
models.py:
#!/usr/bin/env python
import datetime
from django.db import models
class Lock(models.Model):
# id = models.AutoField(primary_key=True)
name = models.CharField(max_length=100,unique=True)
#value = models.IntegerField(null=True)
# No point.. if the record exists, there's a lock, else there
isn't.
info = models.CharField(max_length=1000)
timestamp = models.DateTimeField(auto_now=True)
@classmethod
def clean(self, name, age=0):
# Get a datetime that is offset by 'age' seconds
dt = datetime.datetime.now() - datetime.timedelta(seconds=age)
# Query and delete
old = Lock.objects.filter(name=name , timestamp__lte=dt)
old.delete()
Here's the code that triggers the error.
from locker.models import *
name = "192.168.8.123"
info = "Migrating VIP %s at %s "%("234.34.32.342","12.34.43.22")
lock = Lock(name,info)
lock.save()
now from what i understand django tries to search the table with the
primary key as the name field. But django documentation says it by
default creates an automatic primary key field 'id'. My question is
why does it expect it to be explicitly passed??
