I’m trying to create a form where a logged in user (PrincipalGuest) can update themselves but also multiple guests (AccompanyingGuest). I want an entire form with the attending and dietary_restrictions field embedded within a form, not just the 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):
return self.name
views.py
class RendezvousFormView(SuccessMessageMixin, UpdateView):
template_name = "rsvp.html"
form_class = RendezvousForm
success_url = "/rsvp"
success_message = "Thank you for your RSVP"
def get_object(self):
