Comment (by charettes): Hi ludwik, #26565 is about a different issue. The only way we could support slices would be to extract it from the provided it queryset to make it filterable again and apply it when in- memory joining. The prefect queryset would still have to fetch all results so I'm not sure it's worth the trouble as accessing `category.example_posts[:3]` would have the same effect. -- Ticket URL: <https://code.djangoproject.com/ticket/26780#comment:3> 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.
