Description
I'm currently trying to figure out how to write the correct and efficient query using annotation; much like the example in:
https://docs.djangoproject.com/en/1.3/topics/db/aggregation/
Book.objects.annotate(num_authors=Count('authors')).order_by('num_authors')
Thing is that i know the raw query i want to have but have trouble describing it with the db api; (which i do prefer over inserting raw sql using extra). It may help when the examples are extended with the generated/raw sql queries: select .... etc.
