Changes between Version 1 and Version 2 of Ticket #36157, comment 3

v1	v2
7	7	The thing is prefetching must have `blog_id` otherwise it has no way to build the associative map between `Blog` instances and `Post` to populate `blog.posts.all()`. In other words if I gave you a list of the form `posts = [{"id": 1, "name": "Some blog Post"}, {"id": 2, "name": "Some other blog Post"}` how would you partition it by `blog_id`?

9		Adapting `prefetch_related` to error out if provided an inadequate `Prefetch(queryset)` could potentially be done but that would not solve your actual problem.The third-party library you are using to automatically generate these queries is flawed and should include `blog_id` in the ~~select mask (AKA the `only`) call~~ if it relies on prefetching.

11	11	If you'd like to catch these early I'd suggest looking at the potential solution to have warnings emitted on query leaks in ticket:33835#comment:2.
