Hello,
In my model I have:
def __str__(self):
return _(u'#{0}, {1}, {2}').format(
self.pk,
self.lead and self.lead.customer_name or None,
self.lead and self.lead.customer_phone or None
)
Where self.lead is an optional FK:
lead = models.ForeignKey('Lead', blank=True, null=True,)
If I don't use the and/or syntax above, and the FK *doesn't exist*, I get:
AttributeError: 'NoneType' object has no attribute 'customer_name'
>
While the above and/or syntax works, I'm left wondering if there's a better
way to handle this scenario?
I have several models where the FK may or may not exist upon save. Can
anyone give me tips on how best to handle?
Thanks!
M
