Hello Fernando,
Just as a quick example, you could do something like this:
class Factory(models.Model):
# Assuming suppliers and customers are just two sides of the same
relationship
suppliers = models.ManyToManyField("self", related_name="customers")
Then simply query accordingly:
factory_a = Factory.objects.create()
factory_b = Factory.objects.create()
factory_c = Factory.objects.create()
factory_b.customers.add(factory_a)
factory_c.suppliers.add(factory_a)
