Попытка встроить форму в форму с внешними ключами

Я пытаюсь создать форму, в которой вошедший в систему пользователь (PrincipalGuest) может обновлять себя, а также несколько гостей (AccompanyingGuest). Мне нужна вся форма с полями attending и dietary_restrictions, встроенными в форму, а не только ModelMultipleChoiceField.

models.py

class Guest(models.Model):
    """ """

    attending = models.ManyToManyField("itinerary.Event", blank=True)
    dietary_restrictions = models.ManyToManyField(DietaryRestrictions, blank=True)
    last_modified = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True


class PrincipalGuest(Guest, AbstractUser):
    """ """

    USERNAME_FIELD = "email"
    REQUIRED_FIELDS = []

    username = None
    email = models.EmailField(_("email address"), unique=True)
    phone_number = PhoneNumberField(null=True)
    address = AddressField(on_delete=models.CASCADE, null=True)

    objects = PrincipalGuestManager()

    @property
    def name(self):
        return self.first_name + " " + self.last_name

    def __str__(self):
        return self.name


class AccompanyingGuest(Guest):
    """ """

    principal = models.ForeignKey(
        PrincipalGuest, related_name="accompanying_guests", on_delete=models.CASCADE
    )
    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=20)
    is_under_ten = models.BooleanField(default=False)

    @property
    def name(self):
        return self.first_name + " " + self.last_name

    def __str__(self):
