Re: Django and uuid with PostgreSQL
Yes, it is actually correct, but I'd just like to force uuid generation at database level (postgres supports it) and not via python/django I can modify the table with raw sql after migration and disable default=uuid.uuid4 inside django models, but I'm looking for a better way to accomplish it Il giorno mercoledì 19 ottobre 2016 02:14:23 UTC+2, Tim Graham ha scritto: > > The SQL looks correct -- it's not using anything Python related.

Re: Django and uuid with PostgreSQL
The SQL looks correct -- it's not using anything Python related. Are you encountering some error?

Django and uuid with PostgreSQL
I'm creating a rest api using Django and DRF. I don't want to expose IDs directly to clients so I'm trying to setup my models like this example: class AbstractGuidModel(models.Model): uuid = models.UUIDField(blank=True, default=uuid.uuid4, unique=True, editable=False) class Meta: abstract = True class MyModel(AbstractGuidModel): name = models.CharField(max_length=NAME_LENGTH) Since the AbstractGuidModel has default=uuid.uuid4, uuid are generated by python code and migrations look like: CREATE TABLE "MyModel" ( ... "uuid" uuid NOT NULL UNIQUE, ... ); I've read Postgres has an extension for generating automatically uuids. Once extension is installed, how can I tell django to let database use his own extension and not letting him create them with the Python uuid module? -- You received this message because you are subscribed to the Google Groups "Django users" group.
