Comment (by STANISLAV LEPEKHOV):
Replying to [comment:4 Mariusz Felisiak]:
Thanks for the comments!
I wanted to note that the problem also occurs for the models.ForeignKey
fields.
The migration succeeds (in the absence of links), and after adding the
link, an exception is thrown.
I apologize in advance for the machine translation =)
Here is the code that will throw the exception:
{{{
class StoreChain(models.Model):
places = models.ManyToManyField(Place, blank=True)
class Place(models.Model):
pass
}}}
if change to this edition (set pk with uuid type) and add relation after:
{{{
class StoreChain(models.Model):
uid = models.UUIDField(default=uuid.uuid4, editable=False,
primary_key=True, unique=True)
place = models.ForeignKey (Place, blank=True, null=True)
class Place(models.Model):
uid = models.UUIDField(default=uuid.uuid4, editable=False,
primary_key=True, unique=True)
}}}
