[Python] Column Foreign key is of type bigint but expression is of type uuid in Django

I want to use UUIDField for primary key. This is my model:

class Organization(models.Model):
id = models.UUIDField(default=uuid.uuid4, primary_key=True, editable=False)
name = models.CharField(max_length=124)


All things is good. But when I want to use id of Organization model for ForeignKey in this model:

class Member(models.Model):
reference = models.ForeignKey('Organization', null=True, on_delete=models.PROTECT)
name = models.CharField(max_length=124)


I got this error:

django.db.utils.ProgrammingError: column "reference" is of type bigint but expression is of type uuid
LINE 1: "reference" = 'af104709-...
^
HINT: You will need to rewrite or cast the expression.


What can I do?
