Does postgres cache the settings into a database table? Is there some kind of flush command? I am surprised that this didn't work. This should have been the thing that you needed to do to fix it. Maybe there's a bug in postgres (seems unlikely), or you've done something wrong. I would still work on this front, because this fix is going to be far, far easier to implement and maintain than the alternatives.

You might be able to hook into the database connection routines, and do a SET DATESTYLE on each connection. You probably can get away with doing this in your application code on each connection, and avoid making changes to the Django source; although you do have to then mind django's connection management a bit. It's not efficient, it's not the right way to do it, but for testing it could work. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Sorry for my many posts but i really need to get this solved.
On more observation. From a django shell, this statement works:
>>> sql = 'SELECT "django_session"."session_key",
"django_session"."session_data", "django_session"."expire_date" FROM
"django_session" WHERE ("django_session"."session_key" =
\'996ac580f43dbf6f57028f13ae1537ba\' AND "django_session"."expire_date" >
\'05-09-2008 00:09:52.087243\' )'
Look at the date, i changed the date into a dmY format here instead of Ymd.
This works !
Is there anyway i can force Django to present dates to the database backend as
dmY instead of Ymd. Setting DATE_FORMAT and DATETIME_FORMAT doesn't seem to
have an effect on this.

Benedict

I did some more testing
When i execute the sql from the psql command line, the first time it gives an
error, the 2nd time it doesn't ?! How weird is that :)
Date style is set to 'iso, ymd'

Thanks for the info.
I'm seems i'm unable to set the correct datestyle to get this to work.
When i run it from a python shell, i do indeed get the same error:
python manage shell
>>> from django.db import connection, backend
>>> cursor = connection.cursor()
>>> sql = 'SELECT "django_session"."session_key",
"django_session"."session_data", "django_session"."expire_date" FROM
"django_session" WHERE ("django_session"."session_key" =
\'996ac580f43dbf6f57028f13ae1537ba\' AND "django_session"."expire_date" >

19, in execute
return self.cursor.execute(sql, params)
ProgrammingError: date/time field value out of range: "2008-09-05
00:09:52.087243"
In my postgres.conf, the datestyle is defined as this:
datestyle = 'iso, mdy'
On the database (psql webshop)
webshop=# SHOW DATESTYLE;
DateStyle
---
ISO, MDY
(1 row)
Because the datestyle in the sql statement is passes as Ymd, i tried to set
the datestyle in the postgres.conf file als datestyle = 'iso, ymd' and
datestyle = 'sql, us' but they all resulted in the same error.
Any ideas as to what i need to set datesytle to get it to work?

Judging from the error message, it seems as if the date is in a different format than expected by the database. Any idea of how i can further trace this problem as i'm really stuck here. I haven't even written any code yet so it's a config problem or a bug.

I forgot to mention the following. When i execute the sql statement
from above directly
on the database, it works. No error what so ever.
So the db configuration would appear to be correct.
What could be causing this error ?
Thanks,

ProgrammingError at /admin/, date/time field value out of range
Hi,
on a Debian Etch system, i use Django svn (rev 8911) with Postgres 7.4.
Other components are Apache2 (v. 2.2.3-4) & mod_python.
I created the database with this command:
createdb -E ENCODING UNICODE -U postgres testdb
python manage syncdb runs without a problem.
I installed all components and started a site and activated the admin
site. However, when i go to the admin page, i get this error:
