Hello,
Just in case I have a "XY problem", the actual problem I'm trying to
solve is that I want to be able to read data from two unrelated models
and make sure that the data from each appeared to come from the same
instant in time. In the database, I'd use:
BEGIN;
SET TRANSACTION ISOLATION LEVEL
Dear,
Look at my first post i had .distinct() into it and it didn't work
out, it's pretty obvious why, he does the distinct on the primary key
field (ID) and not on the field hostname, so i get no SELECT Distinct
result as i would like to. Trust me the only way of doing this is my

The behavior of Django sessions changes between "standard" views code
and test code, making it unclear how test code is written for
sessions. Googling this yields two relevant discussions about this
issue:
1. "Easier manipulation of sessions by test client" [http://

Cool, you're all set then. Documentation on Platypus should help you do what
you want. I know it can do tables flow between pages, repeating the header
in the beginning of each page if desired, and I'm sure there are ways of
creating headers and footers, although I have never tried them.
Best,

UmmYes? I'm displaying one message, but only 1, since I'm only
setting 1 per request.
That's probably the issue, but why is more than one message being set
per request,

Hi guys,
How do I add a message (Django 1.2 style) each page load, and have it
cleared after the request?
I set up a middleware running on process_request, but I end up with a
bunch of messages in the admin interface.
My code:
class BetaMessageSet(object):
def process_request(self, request):
Shame on me. The problem was that i mixed SimpleDocTemplate (which the
examples were based on), with BaseDocTemplate, which i used. And
BaseDocTemplate needs an extra PageTemplate defined. So this code
basically works:
def generate_pdf(request):
response = HttpResponse(mimetype='application/pd
Hm, what makes me wonder is this one:
IndexError at /office/job//admin/job/offer/generate/pdf/
This is a url that is not accessible, cause it does not exist, at
least i never defined it in any urls.py.
Maybe thats the problem? Django tries to access a url which doesnt exist?
Greetings

I missed that one out of my example. You're right.
But it doesnt generate a pdf like that, it just complains

Hi everybody,

I found the documentation for a simple reportlab page, using canvas.
But to me it seems, that i need more options than basic Canvas offers.

Well I've implemented the UNTIL functionality by myself adding a field
end_run in models.py:
end_run = models.DateTimeField(_("end run"), blank=True, null=True,
help_text=_("If you don't set this the job will be running

I already found a solution by myself:

Just an idea based on my experience - I'm able to plug on/off tables
on the fly, using database VIEWs.
Such VIEW can be bound to Django model with Meta: managed = False, and
you can bind anything you want
to it (I mean - arbitrary SELECT).

You'd have to build and maintain a little model generator script to
detect a new table, determine its schema, and generate the models.
Then what? Your application detects new models appearing and can
autonomously decide what to do with each one? Sound
