session intermittently disappears just after login

Hi there ... (this is also posted to stackoverflow: http://stackoverflow.com/questions/1504537/django-session-intermittently-disappears-just-after-login) In my django app, I handle login in the following manner. Users go to a gateway page (index.html) - if they are not currently logged in,

Efficiently searching a tree of FKs

Re: Optimizing my ORM query

Sorry for the self-followup, but I got the right bits of extra. My actual case was a bit more complicated than my example below (it involved a fourth model), but it's working now - and much quicker than w/ the IN directive. Thanks. On Fri, 6 Mar 2009, Jeff Gentry wrote: > On Fri, 6 Mar 2

Optimizing my ORM query

Suppose I have three models (in pseudocode): class Foo: asdf = models.CharField() class Blah: qwerty = models.CharField() class Bob: foo = models.ForeignKey(Foo) blah = models.ForeignKey(Blah) Given a Foo and a list of Blahs (where the length of the list might be very small (0-10)

Best practices: generating large dynamic files

In my project I have a need to generate CSV output files for download. Some of these files aren't overly large - 1-20MB or so, but they can get quite big (currently the largest are several hundred MB and this could grow with time). This would appear to be a case where there's no magic bullet,

Re: Views triggering twice

Another piece of info, in case it's useful here - the page does *not* render on the first view call, it's only after the second call that the page will render. I don't think it's even pulling up the template until the second go-around, as a test I put some intentionally bad template code in a

Views triggering twice

In my apps, I'm finding that my views are triggering twice. I have a series of related apps, working off of the same settings.py file (there's a global urls.py, which triggers off of the first string and sends to a subdirectory w/ it's own urls.py/__init__.py/models.py/views.py/etc. With one
