* stage: Unreviewed => Accepted * type: Uncategorized => Bug Comment: The report makes sense. We could go two ways here 1. Clear `distinct_fields` as well as it's unnecessary (we only care about the existence of a single row after all) 2. Avoid [https://github.com/django/django/blob/34a503162fe222033a1cd3249bccad014fcd1d20/django/db/models/sql/query.py#L651 forcing the removal of ordering] since the `clear_ordering` method [https://github.com/django/django/blob/34a503162fe222033a1cd3249bccad014fcd1d20/django/db/models/sql/query.py#L2264 is a noop when distinct fields are defined]. -- Ticket URL: <https://code.djangoproject.com/ticket/35437#comment:1> 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.
