#35499: Issue with auto_now=True DateTimefield and update_fields -------------------------------------+------------------------------------- Reporter: Mohamed | Owner: nobody El-Kalioby | Type: Bug | Status: new Component: Database | Version: 4.2 layer (models, ORM) | Severity: Normal | Keywords: Triage Stage: | Has patch: 0 Unreviewed | Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -------------------------------------+------------------------------------- Let's assume we have the following model
{{{ class Order(models.Model): name = models.Charfield(max_length=25) status = models.CharField(max_length=50, default="Received") order_date = models.DateTimeField(auto_now_add=True) last_update = models.DateTimeField(auto_now=True) }}} Now in one of the views, we want to update the status to "Ready for Shipping" so we write the following {{{ order.status = "Ready to Shipping" order.save(update_fields=['status']) }}} The issue now is that the '**last_update**' field won't be updated in the database as it was NOT included in the `update_fields`. Which I think is dangerous as now the developer has to add the field manually, and even there is no warning or exception that he/she didn't add last_update field -- Ticket URL: <https://code.djangoproject.com/ticket/35499> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
