[Answered ]-Is it possible to create related objects on parent creation automatically in Django?

You can overwrite the save method of the models to do what you want like this

from django.db import models

class Blog(models.Model):
    name = models.CharField(max_length=100)
    tagline = models.TextField()

    def save(self, *args, **kwargs):
        do_something()
        super().save(*args, **kwargs)  # Call the "real" save() method.
        do_something_else()
