Hello!
When i changed this models:
{{{
class StoreChain(models.Model):
places = models.ManyToManyField(Place, blank=True)
class Place(models.Model):
uid = models.UUIDField(default=uuid.uuid4, editable=False,
primary_key=True, unique=True)
}}}
to this edition (set pk with uuid type):
{{{
class StoreChain(models.Model):
uid = models.UUIDField(default=uuid.uuid4, editable=False,
primary_key=True, unique=True)
places = models.ManyToManyField(Place, blank=True)
class Place(models.Model):
uid = models.UUIDField(default=uuid.uuid4, editable=False,
primary_key=True, unique=True)
}}}
Django creates a migration file that affects only the model tables, while
the relationship table remains unchanged, which will cause an error,
because the data type of the _ID fields in it also needs to be changed:
