You can use ForeignKey for many-to-one relationships.

For exapmle, like this.

class Area(models.Model):
    area = models.CharField(max_length=100, blank=True, null=True)

    def __str__(self):
        return str(self.area)


class Cities(models.Model):
    city = models.CharField(max_length=100, blank=True, null=True)
    area = models.ForeignKey(Area, on_delete=models.CASCADE)

    def __str__(self):
        return str(self.city)

See the django docs for detail
