Override save in Django causing infinite recursion error

(Django 2.0, Python 3.6, Django Rest Framework 3.8)

I'm trying to override Django's save() method to post multiple instances when a single instance is created. I have a loop that changes the unique_id which I have saved as a randomly generated string, and the datetime value which is updated through another function called onDay().

My thinking was, that if I changed the unique_id each time I looped around, Django would save the instance as a new instance in the database. But, I keep getting back an infinite recursion error when I run it though. When I checked it with pdb.set_trace(), everything does what it's supposed to until I hit the save() value in the for loop. Once that happens, I just get taken back to the line if self.recurrent_type == "WEEKLY":.

I've used super() in a similar way (without looping) to override the save() function for a separate model, and it worked as expected. I think there's just something I'm misunderstanding about the super() function.

Here is what I have so far:

Overriding save()

def save(self, *args, **kwargs):
        if not self.pk:  # if there is not yet a pk for it
            # import pdb; pdb.set_trace()
            if self.recurrent_type == "WEEKLY":
                LIST_OF_DAYS = self.days_if_recurring["days"]
                HOW_MANY_DAYS_FOR_ONE_WEEK = len(LIST_OF_DAYS)
                REPEATS = HOW_MANY_DAYS_FOR_ONE_WEEK * self.number_of_times_recurring
                RESET_COUNTER = 0
                for i in range(REPEATS):
                    self.id = ''.join(random.choices(string.ascii_letters, k=30))
                    self.calendarydays = onDay(self.calendarydays, LIST_OF_DAYS[RESET_COUNTER])
                    if RESET_COUNTER == HOW_MANY_DAYS_FOR_ONE_WEEK - 1:
                        RESET_COUNTER = 0
                    self.save()
            else:
                self.id = ''.join(random.choices(string.ascii_letters, k=30))
                self.save()
        return super(Bookings, self).save(*args, **kwargs)

onDay()

def onDay(date, day):  # this function finds next day of week, and skips ahead one week if today's time has already passed
    utc = pytz.UTC
    check_right_now = utc.localize(datetime.datetime.now())
    if check_right_now > date:
        forward_day = date + datetime.timedelta(days=(day - date.weekday() + 7) % 7) + datetime.timedelta(days=7)
    else:
        forward_day = date + datetime.timedelta(days=(day - date.weekday() + 7) % 7)
    return forward_day

As always, any help is greatly appreciated.
