Не могу разобраться с конечной точкой DRF.

Я работаю над этой конечной точкой для хранения электронной почты. Я отправляю POST на /emails с { "email": "user101c@email.com" } и получаю ошибку IntegrityError at /emails (1048, "Column 'user_id' cannot be null"). Очевидно, что это ошибка на уровне базы данных. Поле user_id не должно задаваться пользователем. Я не уверен, как действовать дальше.

models.py

class EmailAddress(ExportModelOperationsMixin('email_address'), models.Model):
    user = models.ForeignKey(User, related_name='emails', on_delete=models.CASCADE)
    email = models.EmailField(max_length=255)
    verify_key = models.CharField(max_length=255, null=True, blank=True)
    verified = models.BooleanField(default=False)
    created = models.DateTimeField(auto_now=True)
    verification_sent = models.DateTimeField(null=True, blank=True)
    reset_key = models.CharField(default=None, null=True, max_length=255, blank=True)
    reset_sent = models.DateTimeField(null=True, blank=True)

    class Meta:
        verbose_name = _("email")
        verbose_name_plural = _("emails")
        unique_together = [("user", "email")]
        ordering = ['-created']

    def __str__(self):
        return self.email

    def save(self, *args, **kwargs):
        self.verify_key = get_random_string(length=32)
        if not self.id: # if new
            verify_email_signal.send(sender=self.__class__, email=self.email, key=self.verify_key)
            self.verification_sent = timezone.now()
        super(EmailAddress, self).save(*args, **kwargs)
