[Python-modules-team] Bug#745093: python-model-mommy: doesn't support models with post_save hooks

[Mark Caglienzi]

Package: python-model-mommy
Version: 1.2-1
Severity: normal

Dear Maintainer,
I am using model_mommy with models like this:

class Operator(models.Model):
    user = models.OneToOneField(User)

class OperatorContract(models.Model):
    operator = models.ForeignKey(Operator, null=False, blank=False, related_name="contracts")

def create_user_profile(sender, instance, created, **kwargs):
    if created:
        Operator.objects.create(user=instance)
post_save.connect(create_user_profile, sender=User)
    
When I tell mommy
mommy.make('myapp.OperatorContract')

the test fails with this error:
IntegrityError: UNIQUE constraint failed: myapp_operator.user_id

I tried to clone from the main github repository [0] but the error was
reported as issue #113 [1]. I tried to clone [2] that claimed that the
error was fixed, but I experienced it also in that fork.

Then, finally, I found [3], cloned it, and it solved the issue (at least
for me).

If I understood correctly, it seems that the upstream developer didn't
want to merge the pull request done by tkrajca [4] (and maybe that's the
reason that made limdauto integrate the patch in his fork).

For now I'm using the 'right for me' fork [3], cloned and symlinked in my
project(s), but surely it isn't the best practice...

Kind regards,
Mark
