Just wondering if its possible to set a default tablespace in postgres to keep indexes. Would like the databases to live on the default tablespace for postgres, however, would like to get the indexes on a different set of disks just to keep the i/o traffic separated. It does not appear to me that it can be done without going in and doi...

Hi folks, I'm trying to spit out a django page which lists all entries by the year they were created. So, for example: 2010: Note 4 Note 5 Note 6 2009: Note 1 Note 2 Note 3 It's proving more difficult than I would have expected. The model from which the data comes is below: class Note(models.Model): business = models.Forei...

I looked at django-piston, but I would like to do this with minimum code. Basically I'd like to have something like this: GET /export/applabel/ModelName/ Would stream all instances of ModelName in applab...
I have the same conundrum as presented in this question, but applied to Django's auth.User. I have this proxy model: class OrderedUser(User): def __unicode__(self): return self.get_full_name() class Meta: proxy=True ordering=["first_name", "last_name"] And some of my other models use an OrderedUser i...
I have a problem with needing to provide multiple model backed forms on the same page. I understand how to do this with single forms, i.e. just create both the forms call them something different then use the appropriate names in the template. Now how exactly do you expand that solution to work with modelformsets? The wrinkle, of cour...

I have a database that was already being used by other applications before i began writing a web interface with django for it. The table names follow simple naming standards, so the django model Customer should map to the table "customer" in the db. At the same time I'm adding new tables/models. Since I find it cumbersome to use app_cust...
I have model, Match, with two foreign keys: class Match(model.Model): winner = models.ForeignKey(Player) loser = models.ForeignKey(Player) When I loop over Match I find that each model instance uses a unique object for the foreign key. This ends up biting me because it introduces inconsistency, here is an example: >>> def print...

When I update the new source image, save it and then try to read the source image to crop/scale it to a thumbnail I get an "I/O operation on closed file" error from PIL. If I update the source image, don't save the source image, and then try to read the source image ...

The Django documentation gives en example like so: b = Blog.objects.get(id=1) b.entry_set.all() Which from what I understand results in 2 queries. What if I wanted to get the blog, the blog entries and all the comments associated with that entry in a number of queries that does not depend on the number of entries? Or do I have to drop...
Is there a neat way to make the record/object count for a model appear on the main model list in the django admin module? I have found techniques for showing counts of related objects within sets in the list_display page (and I can see the total in the pagination section at the bottom of the same), but haven't come across a neat way to ...
I saw the next two method on old question here but it is not clear for me what is the difference between: {'date_time_field__range': (datetime.datetime.combine(date, datetime.time.min), datetime.datetime.combine(date, datetime.time.max))} and YourModel.objects.filter(datetime_published__year='2008', ...
