I should point out that this issue with sessions if applicable, isn't actually restricted to a multithreaded server. Technically it could occur with a multiprocess server as well, it just may be easier to trigger a problem when a multithreaded server is used. This issue with sessions previously came up in: http://groups.google.com/group/django-users/browse_frm/thread/a7d42475b66530bd I don't know if there was any subsequent work on Django to look at how big a problem if any this is. Anyway, what was important in what I was saying was not so much the session issue, but that you should just test your system thoroughly to make sure there aren't any problems in general if using a multithreaded server.

Re: Django suddenly loses DJANGO_SETTINGS_MODULE running locally
I didn't dig deeper last night because I was "getting things done" and it was easier to just export the environment and move on. Looking harder at the traceback I noticed it was getting hung up on my putting stuff in the project's __init__.py file which was importing things from Django.

Re: Django suddenly loses DJANGO_SETTINGS_MODULE running locally
The OP isn't talking about Apache but using inbuilt Django server using manage.py. :-) The OP should really post the full traceback and messages there are getting so it can be seen whether they are interpreting it correctly.

Re: Django, CherryPy and threading

How you think mod_python works is wrong, or at least the way you explain it is deceiving in its meaning. In mod_python, each request is not 'serviced by a separate Python instance'. In the case of prefork MPM in Apache, although it isn't threaded and so concurrent requests can't be handled at the same time within a single interpreter instance, successive requests do get handled in the same Python interpreter instance. In other words, the interpreter is not thrown away and instead persists until the process itself is killed, which may only be when Apache itself is shutdown or restarted. In the case of worker MPM in Apache, multithreading is used and so concurrent requests do get handled in the same interpreter at the same time. Again, the interpreter persists for the life of the process. Where confusion often arises and why this myth that a separate Python instance is used for each request persists is that Apache on UNIX is a multi process web server. Thus your requests aren't necessarily all handled in the same process, instead they can be distributed across multiple processes. The use of multiple processes by Apache and the fact that it can create more on demand as load rises, means that Apache is much better able to scale than solutions which use a single Python process with web server implemented in Python only. I really wish this myth about mod_python would die. :-( For a bit more information about the process/interpreter model in mod_python read: http://www.dscpl.com.au/wiki/ModPython/Articles/TheProcessInterpreterModel > This isn't the case with CherryPy though as it's thread based which > leads me to the following concern: is it safe to serve Django with > CherryPy? If one takes the warning in mod_python documentation that only prefork MPM for Apache should be used and worker MPM should not, then it would follow that using the CherryPy multithreaded web server would not be safe. Similarly, it wouldn't be safe to run Django on Windows with Apache either. In practice, discussions in the past have indicated that there are no known multithreading problems in Django itself. Thus the warnings about avoiding worker MPM and thus multithreaded MPMs may not be strictly applicable. Now although Django may be safe for multithreading, you would still need to ensure that your higher level code implemented in Django is multithread safe. You would also need to ensure that you are using recent versions of any database adapters and that they declare themselves as multithread safe. Most importantly, you should rigorously test your application to ensure that it is truly safe to use in a multithreaded web server. Areas which I would suggest you look at closely are use of session objects as these from memory do not provide a locking mechanism, and so in an AJAX heavy application which issues lots of concurrent requests and each handler for them wants to manipulate the same session object, you might run into problems with the handlers and sequencing of operations against the session object.

As Maciej mentioned previously, the easiest way is to use the .extra() call that the DB API provides: things = Thing.objects.extra(where=[""" id NOT IN ( SELECT thing_id FROM myapp_property WHERE property_type_id = %s ) """], params=[42] ) Both Maciej's SQL and the above SQL should be fairly portable as long as you're not porting to some older braindead version of MySQL (pre 4.1, IIRC) that lacks support for subselects [mutters under breath about that *brilliant* decision: "gee, let's omit a hugely useful functionality from ANSI SQL..." I'm not sure I'd even consider pre-5.0 MySQL a "real" database] Some backends prefer "EXISTS" to "IN" (I noticed that for certain cases, using EXISTS in PostgreSQL triggered a monumental speed-up from minutes to seconds) which just takes a minor bit of SQL tweaking to something like where=[""" NOT EXISTS ( SELECT 1 FROM myapp_property WHERE thing_id = myapp_thing.id AND property_type_id = %s ) """] (adjust the name of "myapp_thing.id" to be whatever that fieldname is aliased to) YMMV. -tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I look to iterator() code and it does this thing ok. With some experimenting I saw that mysql backend is probably the worst. Even with iterator mysql sends whole result set and Python DB imitates cursor() semantics. As I said I get 2GB of memory footprint. With SQLite I got only 20MB with same code. So it looks that I have to more think about switching to some other DBMS or to use explicit slicing. For me it could be more appropriate to change iterator() to do some slicing for me (by explicit LIMIT clause), maybe a small patch for our application. I understand, that changing it in general would be a bad design decision.

What's this mean? 'module' object has no attribute 'TagField'
Trying to install django-tagging. I put a copy of the tagging directory in my project folder: MyProject/ App1/ App2/ Tagging/ I ran tagging's setup.py from a separate directory outside of my project folder. Syncdb created tag and tagged_item tables. I added TagField to a model: tag = models.TagField() When I saved the model, the server validated the models and gives me an error: * 'module' object has no attribute 'TagField' What's that mean? -- Austin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

just a guess - if self.fk_day is a ForeignKey field then you'll want to
pass self.fk_day.id here or the expression won't match.
also, i use the permalink decorator for this:

Re: Django suddenly loses DJANGO_SETTINGS_MODULE running locally
This is why, eventhough its noted in the docs as optional, I add the pythonpath to my site in the apache vhosts file by default. Adding the path globally isn't really a good thing to do but adding it whenever your webserver starts the site its needed for, even if its already defined somewhere else, is imho a good practice.

Django, CherryPy and threading
I've managed to get Django working nicely with CherryPy using WSGI. Previously I've deployed Django with Apache and ModPython where each requested is serviced by a separate Python instance. This isn't the case with CherryPy though as it's thread based which leads me to the following concern: is it safe to serve Django with CherryPy?

Django suddenly loses DJANGO_SETTINGS_MODULE running locally

query where m2m field is to have values from one set but not another
I have a model where each Blah can come from one or more Sources. i.e. I have: class Blah(models.Model): ... sources = models.ManyToManyField(Source) The query I want to perform is to find all the Blahs that come from sources 1 or 2 but not sources 3 or 4. My first attempt was: Blah.objects.filter(sources__id__in=[1, 2]).exclude(sources__id__in= [3, 4]) but that just returns all Blahs (the filter(sources__id__in=[1, 2]) is definitely wrong) The SQL I want to run is something like: SELECT blah_id FROM myapp_blah_sources WHERE source_id IN (1, 2) EXCEPT SELECT blah_id FROM myapp_blah_sources WHERE source_id in (3, 4); and this seems to work. Note it's directly referencing the m2m relation. What's the best way to express that SQL query in the database API? Note that the lists [1, 2] and [3, 4] are actually coming from a form and may be empty, in which case the WHERE clause could be eliminated on that side of the EXCEPT.

hi,
when i upgraded to the latest svn head, I found that all the places
in admin that had drop downs for choices were blank. I had always
marked my choices for translation like so:
article_type = (
("NW", _("News")),
("FT",_("Features")),
)
now, this doesnt work - when I remove the _(), then the choices
appear. How do I then mark them for translation?

Ah, forget it. You wrote that it worked fine with older versions, so it can't be psycopg2. I'm really busted here. Please understand that I simply don't have the time to set up a SuSE box for this. As a last resort, you could try to find out at which line in the code the process aborts by adding print statements in the django database backend to psycopg2, or by single-stepping through the code with pdb.

Re: problems with tutotial !?
no! I don't arrive at that part of tutorial yet.
and is very strange for me.
I started from the beggining.
When I change from:
class Admin:
pass
in to
class Admin:
fields = (
(None, {'fields': ('pub_date', 'question')}),
)
it dissapear from admin.
If I change it back, it doesn't apear back in admin.
Why ? Is that normal ?

changing versions
Hi, I had finally decided to see if the new svn version of django fixed an issue I was having (ticket 1796 - fixed in rev 5919). So I ran svn update and checked out rev 6022, restarted apache and unfortunately got an "Internal Server Error" visiting the website. So I starting to checkout different versions to see where the problem was. I dont think I am using the correct svn command... when im in the .../python2.5/site-packages/django directory, I use #sudo svn co -r 5918 http://code.djangoproject.com/svn/django/trunk/ (I cant remember when I found it) Is that how I revert back to a previous version? When I run svnversion i get 6022, when I run svnversion trunk/ i get 5918... Which version will django be using? Im guessing 6022, but if so, how do i get it to use 5918? Any suggestion what could be causing the Internal Server Error? or how go about figuring it out?

Re: UnicodeDecodeError with memcache
additional information: I just checked the default encoding >>> import sys >>> sys.getdefaultencoding() 'ascii' should that be something different (like utf-8)? btw: all our data (database) and scripts are encoded with utf-8. thanks, patrick On 28 Aug., 08:21, patrickk <[EMAIL PROTECTED]> wrote: > I´m sorry for bothering again, but our site has to be online soon and I > ´m currently not able to use the cache_page decorator (which makes me > a bit nervous). > I did some research on smart_str, but I don´t know how and where to > use it and I also don´t see why this should solve the problem. > > any feedback is highly appreciated. > btw: I´m able to use the low-level cache. > > thanks, > patrick > > On 27 Aug., 16:52, patrickk <[EMAIL PROTECTED]> wrote: > > > so you say I should use __str__ instead of __unicode__, right? > > according to the django-docs, that´s not recommended though ... > > > On 27 Aug., 16:40, Iapain <[EMAIL PROTECTED]> wrote: > > > > > UnicodeDecodeError at /spezialprogramme/ > > > > 'ascii' codec can't decode byte 0x80 in position 0: ordinal not in > > > > range(128) > > > > try using smart_str, it it doesnt work then use less restrictive decode --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: UnicodeDecodeError with memcache
I´m sorry for bothering again, but our site has to be online soon and I ´m currently not able to use the cache_page decorator (which makes me a bit nervous). I did some research on smart_str, but I don´t know how and where to use it and I also don´t see why this should solve the problem. any feedback is highly appreciated. btw: I´m able to use the low-level cache. thanks, patrick On 27 Aug., 16:52, patrickk <[EMAIL PROTECTED]> wrote: > so you say I should use __str__ instead of __unicode__, right? > according to the django-docs, that´s not recommended though ... > > On 27 Aug., 16:40, Iapain <[EMAIL PROTECTED]> wrote: > > > > UnicodeDecodeError at /spezialprogramme/ > > > 'ascii' codec can't decode byte 0x80 in position 0: ordinal not in > > > range(128) > > > try using smart_str, it it doesnt work then use less restrictive decode --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
