Re: Overriding save to create and save related entity
It is possible to override the save() method in a model to add functionality: https://docs.djangoproject.com/en/dev/topics/db/models/#overriding-model-methods Another choice would be to register a receiver for the pre_save or post_save signals: https://docs.djangoproject.com/en/dev/ref/models/instances#what-happens-when-you-save https://docs.djangoproject.com/en/dev/topics/signals/ Either method can be used, the choice depends on your desired architecture. I prefer overriding save() for changes to the model itself or its related models (as in this case), and signals less related features (for example sending an email).

Overriding save to create and save related entity
Hi all, I have the following code: class Points(models.Model): blah blah class TrainingSession(models.Model): confirmed = models.BooleanField() points = models.ForeignKey(Points, null=True, blank=True) When a training session is saved, if confirmed is True I wish to create and save a points instance. How can I do so? -- Regards, Sithembewena Lloyd Dube -- You received this message because you are subscribed to the Google Groups "Django users" group.
