Hello,
I am using django-1.6.b2 on a localserver (./manage.py runserver) and
for every request I have the chain of db lookups made twice. For
example my log looks something like this (after enabling
django.db.backands logger):
# HERE VIEW IS CALLED
(0.001) SELECT "django_session"."session_key", "django_session"."session_data",
"django_session"."expire_date" FROM "django_session" WHERE
("django_session"."session_key" = '2dh8ly6cfqkyiauv8co5h1vossjg70ru' AND
"django_session"."expire_date" > '2013-08-31 11:04:33.597734+00:00' );
args=('2dh8ly6cfqkyiauv8co5h1vossjg70ru', u'2013-08-31 11:04:33.597734+00:00')
(0.001) SELECT "auth_user"."id", "auth_user"."password",
"auth_user"."last_login", "auth_user"."is_superuser", "auth_user"."username",
"auth_user"."first_name", "auth_user"."last_name", "auth_user"."email",
"auth_user"."is_staff", "auth_user"."is_active", "auth_user"."date_joined" FROM
"auth_user" WHERE "auth_user"."id" = 1 ; args=(1,)
#... (AND SO ON)

# DB LOOKUPS ONCE AGAIN:
(0.001) SELECT "django_session"."session_key", "django_session"."session_data",

any ideas why?
The views (as it is not just one) returns using render(). This also
happens when using DetailedView cbv.
I also setup looking on postgres (which I use) and indeed the queries
are made twice.
Thanks for ideas,
Marcin
