Django users:
I'm currently trying to deal with something that works just fine in PSQL
but causes django some headaches. I have a model like this:
class Application(models.Model):
... #other stuff
paired_with_app = models.ForeignKey(
'Application',
blank=True,
null=True,
)
Everything works great in SQL and in django until I get two rows that use
this foreign key to refer to each other. When this happens, any query
involving a row involved in a circular reference takes 6 seconds longer and
spits out the python "avoid infinite recursion" error message,
"Exception RuntimeError: 'maximum recursion depth exceeded in
__subclasscheck__' in <type 'exceptions.RuntimeError'> ignored"
How do I get django to tolerate the circular reference without trying to
follow it ad infinitum? All of the code we use it for doesn't follow any
references, which means that we're currently setting this foreign key field
to the IntegerField "paired_with_app_id" as a workaround.
Thanks,
