it would be nice, of querysets injected objects where used as query
parameters to the result set
example using the polls app from the tutorial
{{{
#!python
from polls.models import *
from django.db import connection
Poll.objects.get(id=1).choice_set.all()[0].poll
}}}
results in 3 queries, since the related manager wont pass the orginal poll
object to the instances of the choices
after this code connection.queries is
{{{
#!python
[
{'time': '0.000',
'sql': 'SELECT
"polls_poll"."id","polls_poll"."question","polls_poll"."pub_date" FROM
"polls_poll" WHERE ("polls_poll"."id" = 1)'},
{'time': '0.000',
'sql': 'SELECT
"polls_choice"."id","polls_choice"."poll_id","polls_choice"."choice","polls_choice"."votes"
FROM "polls_choice" WHERE ("polls_choice"."poll_id" = 1) LIMIT 1 '},
{'time': '0.000',
'sql': 'SELECT
"polls_poll"."id","polls_poll"."question","polls_poll"."pub_date" FROM
"polls_poll" WHERE ("polls_poll"."id" = 1)'}]
}}}
the same query twice just cause a python object doesn't get passed
