django-batch-select (via) A smart attempt at solving select_related for many-to-many relationships in Django. Add a custom manager to your model and call e.g. Entry.objects.all()[:10].batch_select("tags") to execute two queries - one pulling back the first ten entries and another using an "IN" query against the tags table to pull back all of the tags for those entries in one go.
