#35690: Calling queryset.in_bulk() after queryset.values() or queryset.values_list() results in unhelpful error -------------------------------------+------------------------------------- Reporter: john-parton | Type: Bug Status: new | Component: Database | layer (models, ORM) Version: 5.1 | Severity: Normal Keywords: | Triage Stage: | Unreviewed Has patch: 0 | Needs documentation: 0 Needs tests: 0 | Patch needs improvement: 0 Easy pickings: 0 | UI/UX: 0 -------------------------------------+------------------------------------- Calling {{{ MyModel.objects.values().in_bulk() }}}
Results in a rather annoying error message that doesn't help the user. {{{ Traceback (most recent call last): File "<console>", line 1, in <module> File "/home/john/Code/ecom/.venv/lib/python3.12/site- packages/django/db/models/query.py", line 1156, in in_bulk return {getattr(obj, field_name): obj for obj in qs} ^^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'dict' object has no attribute 'pk' }}} This is because the `in_bulk` method assumes that the queryset has the default `_iterable_class` (`ModelIterable`) and is attempting to access a property on an object, but the `_iterable_class` returns dictionaries. The correct behavior should be either to: 1. Raise a more helpful error if the user attempts to call `in_bulk()` where the _iterable_class isn't the standard ModelIterable; or 2. Define behavior for when `in_bulk()` is called in that case. (I think that might be rather challenging, so Behavior 1 is probably the better option.) -- Ticket URL: <https://code.djangoproject.com/ticket/35690> 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.
