Malcolm Tredinnick 0a89a57ffc Fixed deferred fields and select_related() interaction.
Loading related models when some fields were deferred was resulting in
incorrect offsets being used into the results row, causing the wrong data to be

Malcolm Tredinnick dded5f52cc Fixed #10695 -- Fixed implementation of deferred attribute retrieval.
The original implementation had a few silly bugs in it that meant that data was

In extreme cases, some fields are expensive to load from the database

commit adds defer() and only() methods to querysets that allow the
caller to specify which fields should not be loaded unless they are
accessed.

Malcolm Tredinnick f747b61c20 Nested query support.
This extends previous functionality that allowed passing Query objects as the

opaque attributes. See the documentation of the "__in" lookup type for the
details.

Malcolm Tredinnick 44f228fd61 Fixed #6748 -- When printing the repr() of querysets, don't load or display
more than 20 objects.

This means that accidentally executing HugeStoryArchive.objects.all() at the
interactive prompt (or in the debug template) won't try to load all 4,233,010
stories into memory and print them out. That would previously cause resource
starvation and other "interesting" crashes.

If you really, really want the previous behaviour (e.g. in a doctest that
prints more than 20 items), display "list(qs)" instead of just "qs".
