New description:
When I run dumpdata with a model which has a UUIDField as a natural key,
the dump can not be loaded anymore.
{{{
manage.py dumpdata --natural-foreign myapp
manage.py loaddata myapp
}}}
The model :
{{{#!python
class ApplicationManager(models.Manager):
def get_by_natural_key(self, uuid):
return self.get(uuid=uuid)
class Application(models.Model):
uuid = models.UUIDField(unique=True, default=uuid.uuid4,
editable=True)
...
}}}
The dump looks like this
{{{
[
{
"model": "accounts.applicationrole",
"fields": {
"application": [
"ec1e39cb-e3e7-46c7-87b7-70ace4165d13"
],
...
}}}
The error message in loaddata is:
{{{
'(UUID('ec1e39cb-e3e7-46c7-87b7-70ace4165d13'),)' is not a valid UUID.
}}}
