#28722: reverse_ordering does not reverse nulls_first/nulls_last -------------------------------------+------------------------------------- Reporter: Tomer | Owner: Tomer Chachamu Chachamu | Type: Bug | Status: assigned Component: Database | Version: 1.11 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 | -------------------------------------+------------------------------------- The documentation for Expression.reverse_ordering says it is its own inverse:
https://docs.djangoproject.com/en/1.11/ref/models/expressions/#django.db.models.Expression.reverse_ordering > Returns self with any modifications required to reverse the sort order within an order_by call. As an example, an expression implementing NULLS LAST would change its value to be NULLS FIRST. Modifications are only required for expressions that implement sort order like OrderBy. This method is called when reverse() is called on a queryset. However, this isn't implemented. https://github.com/django/django/blob/2b5a511bd9fbd67cedf72b8d39b9522c0140d023/django/db/models/expressions.py#L1133 -- Ticket URL: <https://code.djangoproject.com/ticket/28722> 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.
