Re: Spawning long processes
Ahhh, I got it now - Thanks so much Simon! The problem was I had left
out close_fds, so it was still spawning as a child process I think.
With close_fds it works a treat - thank you once again :D

Re: Spawning long processes
That doesn't work, I've tried that, it still hangs the view.
Give it a shot with a long python script (while True: time.sleep(1)
would do) and you'll find that the view never returns. If you can get
it to return, I'd love to see your code, but it's no go for me...

Re: Spawning long processes
Just to give an update, I've tried forking the view, and then turning
the child process into a daemon with a double fork, and then exiting
before it gets to the return, and letting the parent do the return,
but this is not working either...
I'm stumped, and don't really want to have to create a specific

Spawning long processes
Hi
I'm currently playing around trying to make something akin to
TorrentFlux, using Django. TorrentFlux is a system that's PHP and it
calls shell scripts to download torrents in the background, with a web
interface to control them. For every torrent download, a new process
is started, which runs with the torrent - downloading and seeding it.
My system is similar, and i'm at a very proof of concept stage at the
moment. However, I've hit a problem. I can't find a nice way to spawn
the processes, without Django hanging as long as the process needs
(and for 600mb torrents, that's gonna be hours, and endless if seeding
is expected).
At the moment I am doing:
def start(request):
p = os.spawnlp(os.P_NOWAIT, 'python', 'python', '/Users/acid/Work/
dTorrent/btdownloadheadless',
'/Users/acid/Desktop/Inbox/-{mininova.org}- Professional C+
+.torrent')
t = Torrent.objects.create(pid=p)
return HttpResponse(str(p))
But this is hanging, despite the P_NOWAIT (the Torrent model does get
created).
Any ideas?

Re: get the latest # of objects
Try Entries.objects.order_by('a_field_that_you_want_to_order_by')[:5]
Entries.objects is a query set manager, not a query set, so you can't
slice that.

Damnit, that's what you get for trying to run several projects under one vhost on apache!

Re: reverse relationships with ForeignKey?
Thats' because by default Django will name the field "model_set" on the
reverse relationship. So if you want to access it that way, you should
do entry.updates_set.all(). A nicer, more readable way, is to set
related_name on the ForeignKey. E.g: entry = models.ForeignKey(Entry,
related_name="updates") (This is a field in your Updates model)
Hope this helps!

Another take on auto-history
Morning all I've been meaning to post this to the list for a while, and I think my code is now ready to be shown. I've been working on a small bug tracker type project for myself - as I have 3 Django projects on the go at the moment. Anyway, I wanted a way to track changes made to bugs/tickets so I made this automatic history decorator. It works by logging revisions of fields on a model, so you can specific which fields should have a history, etc. I haven't included rollback support yet, but if people are interested, I will happily look into offering it (shouldn't be hard!) Without furthor ado, here is the website, with a mini example application too: http://acid2.user.openhosting.com/history/ The way that my auto history module works is through decorating the save() method of a model. Everytime you save a model, it looks up the model in the database first. Then, each field is compared and log entries are made. You can then retrieve a list of these changes through the models provided (see the example in the zip). This was mainly an experiment to learn introspection and metaprogramming type stuff in Python, but if anyone has any ideas on what could improve this, I'd love to hear them.

Re: how to connect Django to objects served over xml-rpc?
Hey, seeing as you haven't had any relies yet, I will through my idea down. What I think you're gonna have to do for the most graceful version is to create your own database wrapper, that calls xml-rpc, instead of an actual database. Then Django *should* be free to use. The problem may occur that Django really does expect to see database like data, so you may have to reformat your data. My only other idea is to extend the model base class, and replacement the save function, etc. This will get messy though, because QuerySet's also use the db api, so it would require rewriting them too. I think that option 1 is your best bet, and looking at the SQLite wrapper should make stuff easier. Hope this helps -- Ollie > I want to try out Django for a small project, hoping to discover that > it will be the web framework of my dreams, but I need some advice. > > My project group has written an xml-rpc API in front of our database > and password stores.

Re: Django Urls object_id/xxxxxx/object_id
Just write your own view that in turn calls a generic view? Create a new view, with a similiar signiture, but change the object_id for team_id AND result_id. Then, do a bit of logic to find the query set you need a view of, and pass this through to a generic view, and then return this.

Re: multiple urls for the same view?
No, what I mean is more like this. You have one set of urls that act
like a master. Each url should be
similar to
('something/$', 'view-handler')
Notice that it doesn't use ^, so it will match anywhere. Then, on your
seperate sites, you have a site
specific url config that includes this master url file, so you can have
the urls with anything else before
them. So if the site specific looked like:
urlpatterns = ('', ('^dev1/', include('appurls'))
Then the url /dev1/something/ would be matched, but you could change
dev1 to dev2 and it
would still match.
Please let me know if I've misunderstood what you're trying to do, but I
hope this clears what I
meant up.

Re: multiple urls for the same view?
Yea, there is a way. If you take all your url out, and move them into an
appurls.py file or something,
you can include this from the main urlpatterns. E.g:
urlpatterns = ('', ('^yourprefixhere/',
include('pythonpathtoproject.appurls'))
I think that should work - there might be other ways though.

Re: Django Schema Migration
Hey, this is neat! It's just a shame that it doesn't use Python models or some type of database agnostic representation - any plans there?

Re: Extending the User model
I suppose the best bet, in an ideal world, world be model inheritance. As you're probably aware, this is incomplete at the moment, so you can't really do that. A better solution may be to have a wrapper model, and have your Buyer/Seller classes create one to one relationship this extension class. To top things off, one-to-one is also going to be changing syntax soon.. but I think this is your best bet for now... class UserExtension(models.Model): pass class Buyer(models.Model): # Buyer specific profile data here pass Then, you could set AUTH_PROFILE_MODULE. To keep your code pretty dry, you'll probably want to have a "get_data" method in UserExtension: def get_data(self): if self.buyer: return self.buyer if self.seller: return self.seller return None # No profile data I'm also looking for a nice solution to this, as I'Hope this helps On Apr 19, 9:05 am, checco <[EMAIL PROTECTED]> wrote: > Hi, > > I already posted this question > herehttp://groups.google.com/group/django-users/browse_thread/thread/2dfb... > but I then realized I had not been very clear and decided to rewrite > it. > > In this entry from the James Bennet > bloghttp://www.b-list.org/weblog/2006/06/06/django-tips-extending-user-mo... > are clear instructions on how to extend the User model to fit the > particular needs of an application. > > In the application I'm developing there two different kind of users, > for example a Buyer and a Seller, which have different fields.

Re: ImportError: no module named django
Ok, I took the last email private with Rob, and got it sorted! It seemed that apache couldn't access any files in /home/acid2, so the solution has been to move everything into /opt/django, so I did: sudo mv /home/acid2/src/django_src/ /opt/django/src/ sudo rm /usr/lib/python2.4/site-packages/django sudo ln -s /opt/django_src/django /usr/lib/python2.4/site-packages/ django Also, I store my projects and their templates in /opt/django_projects and /opt/django_templates, respectivly. Quick hint that i'll pass on from Rob (that I'm sure many people know) - settings.py contains sensitive information, so I have made this private with: chmod 0750 /whatever/settings.py chown root:apache /whatever/settings.py Now it's read/write/execute for root, and only read/execute for apache. Hurrah!

ImportError: no module named django
Ok, I've done a ton of googling on this, and not come up with much luck. Here's my situation: I've just purchased a new VPS from OpenHosting for a project, and it comes with mod_python, apache2 and postgresql all setup. So I did a subversion checkout of django, and symlinked it to /usr/lib/python2.4/ site-packages, which I can verify: [EMAIL PROTECTED] ~]$ ls -al /usr/lib/python2.4/site-packages/ | grep django lrwxrwxrwx 1 root root 33 Apr 18 14:27 django -> /home/acid2/src/ django_src/django So that looks ok, and just to make sure, here's django_src/django: [EMAIL PROTECTED] ~]$ ls -al ~/src/django_src/ | grep django drwxr-xr-x 20 acid2 acid2 4096 Apr 18 14:27 django So, with django now symlinked to my site-packages, I tried importing it in the python shell: [EMAIL PROTECTED] ~]$ python Python 2.4.3 (#1, Mar 14 2007, 18:51:08) [GCC 4.1.1 20070105 (Red Hat 4.1.1-52)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import django >>> Looks good!

Extending feeds with Apple iTunes information?
I'm using the feed system to do a podcast, and it's up on the iTunes Store as well. But I'd like to make it more user friendly, taking advantage of the images that are supported, and extended meta data. Is there anyway to add my own namespaces into the feeds, or am I going to have to get my hands dirty with Django's internals and add that myself?
