I am new to django - have used established installations before but am
setting it up for the first time now. I am using vista 64 bit, the
current SVN tree, python 2.5.2 and sqlite and pretty much following
the tutorial. Everything went fine until I tried to access the admin
page (I can sync the databases etc, have added content and models).
I get a trackback (see below) when loading the admin page. It looks
superficially like a db access problem but I have done the path
correctly (fwd slashes), checked permission, monitored file access at
the OS level (django opens and closes the sqlite file ok) and then in
sheer frustrating added print statements to track django's access to
sqlite. It does successfully open and close the database several
times, creating the session entries for example using these queries
(and I've verified it puts things into the sqlite db)
'SELECT "django_session"."session_key", "django_session"."ses
sion_data", "django_session"."expire_date" FROM "django_session" WHERE
("django_
session"."session_key" = %s AND "django_session"."expire_date" >
%s )'
'SELECT (1) AS "a" FROM "django_session" WHERE "django_sessio
n"."session_key" = %s '
It then closes the database and *after* closing, tries the call stack
below which seems to blow up because the database isn't open. It's
driving me nuts and has left me feeling less than enthusiastic about
django having wasted a good day so far troubleshooting. Any help
greatly appreciated
