Unfortunately, I don't think this will work very reliably: the time of
update and time of creation will be a little bit different, so I can't
check for strict equality, but the two UserProfile save events occur close
together, so I can't choose a reliable timedelta to ascertain whether the
instance is begin saved the first time or the second time. For example, the
output from
def email_admins_on_new_signup(sender, instance, **kwargs):
print('created:', instance.profile_created)
print('updated:', instance.profile_updated)
is:
created: 2017-02-02 10:53:51.575074+00:00
updated: 2017-02-02 10:53:51.575115+00:00
created: 2017-02-02 10:53:51.575074+00:00
updated: 2017-02-02 10:53:51.578555+00:00
A workaround is:
if not kwargs['created'] and instance.profile_updated -
instance.profile_created < timedelta(seconds=5):
# Only send an email if a new UserProfile was created.
send_signup_alert_email_to_admins(instance)
– i.e. only send the email if the instance save is after initial creation,
but within 5 seconds of it, but that feels awfully hacky and I'd love a
better solution.
