Re: UUIDs eventually choke as primary key

Not to belabor the point, but this is the part that I find weird. This is down in the "During handling of the above exception ('UUID' object has no attribute 'replace'), another exception occurred" section.

/usr/local/venvs/attrack/lib/python3.6/site-packages/django/db/models/fields/__init__.py in to_python

        if value is not None and not isinstance(value, uuid.UUID): <<-------- 1) CHECKS FOR NOT UUID

            try:

                return uuid.UUID(value)  <<----- 2) Pretty sure first exception is in here

            except (AttributeError, ValueError):

                raise exceptions.ValidationError(

                    self.error_messages['invalid'],

                    code='invalid',

                    params={'value': value}, <<------  Traceback says new exception here

                )

        return value

Local vars

Variable Value

self <django.db.models.fields.UUIDField: id>

value UUID('338fa43f-3e07-4e83-8525-d195d2fc64d4')  <<-------- 3) REPORTS AS UUID

So, if 3) is right and 'value' is a UUID, 1) should keep us from getting to 2). But we get there.

Adding details I seem to have left out. The id is defined like this:

id = models.UUIDField(primary_key=True, default=uuid.uuid1, editable=False)

and I'm running on PostgreSQL.

I'm pretty sure I never create a row without already having the key.
