#27342: update_or_create example is misleading -------------------------------+------------------------------ Reporter: kakarukeys | Owner: nobody Type: Bug | Status: new Component: Documentation | Version: 1.10 Severity: Normal | Keywords: update_or_create Triage Stage: Unreviewed | Has patch: 0 Easy pickings: 1 | UI/UX: 0 -------------------------------+------------------------------ In the documentation about update_or_create, the following code
{{{ try: obj = Person.objects.get(first_name='John', last_name='Lennon') for key, value in updated_values.iteritems(): setattr(obj, key, value) obj.save() except Person.DoesNotExist: updated_values.update({'first_name': 'John', 'last_name': 'Lennon'}) obj = Person(**updated_values) obj.save() }}} is said to be practically the same as: {{{ obj, created = Person.objects.update_or_create( first_name='John', last_name='Lennon', defaults=updated_values) }}} however, in the former, updated_values is overwritten by John Lennon dictionary. whereas, in the latter, John Lennon dictionary is overwritten by update_values. suggested code change: {{{ except Person.DoesNotExist: new_values = {'first_name': 'John', 'last_name': 'Lennon'} new_values.update(updated_values) obj = Person(**new_values) obj.save() }}} -- Ticket URL: <https://code.djangoproject.com/ticket/27342> 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.
