Re: Many2Many question about Database API
I see where this has already been addressed in ticket #2457
http://code.djangoproject.com/ticket/2457
Apparently it's a bug in the version of sqlite that's bundled with the
Windows installer (3.3.4).
The command line version of sqlite that I'm running is much more
recent, which explains the different results.
I originally thought it was just a misunderstanding on my part of the
docs or else I would have researched it a little more before posting.
Thanks for the help.

Re: Scalability / Traffic-Volume Numbers
I'm starting off with everything on 1 server. As for traffic at the start I'm looking at 2000-3000 hits/10K - 20K page views per day. Maybe I should have asked this instead : If you used one of www.slicehost.com VPS's (say the 512MB ram one).. from any experience you may have on similar setups, running everything on a single server.. how would you configure it for optiminal performance? assuming it was a very dynamic Django + MySql site. And.. what you think visits/pageviews wise... how many this server would be able to handle (just off the top of your head - no hard facts needed).. thanks cheers. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

The biggest question to ask here is what level of traffic you're expecting, and how quickly you expect that traffic to go; there are lots of things you can do to your setup to optimize for different traffic levels, so it's very hard to give a concise answer to "what can this server handle". Generally your biggest RAM sinks are going to be (not necessarily in this order): * memcached, if you're using it * Apache/mod_python, if you opt for that as the web server setup * Your database server For most situations, focus first on how much RAM you give to the database, because the database is almost always the first bottleneck in scaling (and because a huge memcached instance with a blazing-fast web server is no good if you can't get at the data to put it in the cache), then look at other concerns. If memory is a significant concern, you may also want to look at using lighttpd and FastCGI; lighttpd isn't always the ideal choice, but you can squeeze a little extra performance out of it by taking advantage of its relatively low memory use compared to Apache with prefork MPM (though bear in mind that you'll still have memory overhead from FastCGI processes). -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

You have 3 categories and 3 content objects, but what is in the m2m

They will only be the same if the m2m relations between the objects
are correct. At is, it looks like all three content objects are
related to the first category.

No - they apply to both. The query language makes no distinction
between M2M and M2O relations.

Re: extends blocks don't cache parent templates?
Hi Malcolm, Thanks for the reply. This issue is definitely seems to responsible for a good chunk of the time it takes for django to return a response in my app, about 70 ms to be precise. Basically, I'm rendering a page which has a list of Template'd objects, each of which inherits/extends from a base template. This means that in the course of a listing of, say, 25 things, I'm seeing 27 disk-hits/read/parse/tokenize (two for the page's own template, and then one for each of the items, all of which inherit from the same base template), which in total account for the 70 ms of CPU time. Perhaps this is a "pathological" use of the templating engine, but seeing as I'd like each item in the listing to be one of a variety of object types (with some shared UI components), it seemed reasonable to use template inheritance. Having made a bit of a forray into the source code, the behavior I'm looking for seems possible by changing the return call at the end of ExtendsNode.get_parent from return get_template_from_string(source, origin, parent) to self.parent_name = get_template_from_string(source, origin, parent) return self.parent_name This seems to make everything down the line render happily, given that the case of self.parent_name being a Template is handled already properly, but, of course, I can't tell if it will instead break features that I'm not currently using. It cuts out the 70 ms lag, at least.

For many cases, that branch is usable at the moment, although you can see from the "todo" section that there is still a little work to do. Try it out. Report bugs (prefix any bug ticket titles with "unicode:" so that they show up in searches). See the "Porting Applications" section for changes you'll need to make to your code (and I'd like to hear reports -- via Trac -- of anything I've omitted there). The one big case where it won't behave correctly is if you have a site where the content can be in multiple languages that are decided at request time (some things won't be translated correctly).

Is this behaviour a critical slowdown in the performance of your application? There are many micro optimisations that are possible in the template system (including caching pre-compiled templates), but the experience from the original developers was that they simply weren't necessary. It isn't a huge performance hit, in general. If you have performance numbers that show it really is a major component of the time budget for a request on templates that are "reasonable" (not pathological cases), that would be interesting to see so that we could look at what might be necessary.

Generally, you don't want __str__ to return a Unicode string; if you need to get Unicode out of it, have it return a UTF-8-encoded bytestring. To return a Unicode string directly, instead define the __unicode__ method to return that, and probably a __str__ which returns the result of __unicode__ encoded as a UTF-8 bytestring.

__str__() returning unicode strings
Hi, I've some models where the strings returned by __str__() are unicode strings and contain non-ascii characters, especially umlauts. With a recent Django version, this causes UnicodeEncodeErrors all over the place. Could anybody give me a hint on what I have to do to work around this issues except using ascii characters only?

extends blocks don't cache parent templates?
I'm working on a project which is making rather copious use of extends blocks, and I've noticed that every time an extends block is executed, django seems to hit the file system, reads the file, and compiles the parent template. This behavior seems to be independent of whether that particular parent template has been seen and compiled before. I've traced the problem to ExtendsNode in loader_tags.py, where get_parent is called when render is executed. It seems like the resulting rendered parent Template object is never cached, so subsequent hits to render end up reloading the template from file again. Is there a settings flag that I'm missing to enable caching? Has anyone seen this before?

Many2Many question about Database API
First, since this is my first post to this group, let me say that
Django is phenomenal. So serious. In fact, "phenomenal" doesn't even
begin to scratch the surface . . . using that phrase to describe it is
an insult! Many, many thanks to everyone who has contributed!
On to business . . .
I have 2 models that I'm using "for training": Content and Category
with a ManyToMany field in Content to relate them.
For test data, I have entered 3 categories and 3 pieces of content
(one in each of the 3 categories).
In my understanding of the docs, I expected to be able to use the line
of code below to retrieve all pieces of content in the category with a
slug of 'list-1'. However, that appears to not be the case, as every
record from Content is returned.
>>> Content.objects.filter(categories__slug__exact = 'list-1')
[, , ]
The results I actually want to get are accomplished via the following:
>>> a = Category.objects.get(slug = 'list-1')
>>> a.content_set.all()
[]
Should I expect these to be the same (in which case I'm doing
something wrong) or does the section in the docs here ("Lookups that
span relationships") . . .
http://www.djangoproject.com/documentation/db-api/#lookups-that-span-relationships
. . . only apply to One-to-many relationships?
Thanks for any help.
BTW, I'm using 0.96

Off the top of my head, one thing is that many-to-many fields won't work, since there won't be entries in the intermediate table corresponding to the new id you will get.

Re: Is it really this hard?
James, Thanks again so much. I think i tried the commit=False bit but it still didn't like my FK being blank for some reason. I'll have to look through the django source and double check. So, assuming my commit=false works, i should be able to say something like: form.clean_data['fk_id'] = fkobjid ?

Re: Constraints to a model
The simplest way I can think of is to override the model .save() method and enforce your constraint there before calling the parent class save method. def save(self,*args,**kwargs): if bool(self.arts_id) | bool(self.pics_id): super(Post,self).save(*args,**kwargs) else: raise some kind of validation error here --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Flatpages render using RequestContext, so you'd use a template context

Already done, though under-documented.

Add this to INSTALLED_APPS:
'django.contrib.markup'

Re: Is it really this hard?
Russ,
Thanks for info, but what happens when the form.save() is called,
since the FK isn't part of the clean_data, it will fail no?
I think i've gotten to the point where I can get it off the form, but
now how do I make it so I can update the FK in code on the POST?
Thanks everyone for continuing on this thread, but I still don't like
the portion of the newforms stuff, and I know it's not done, so I hope
this can help improve it.
The other option is using a charfield widget that is hidden with the
FK, but doesn't that lend myself to hacking? I'm SO new to web stuff
that I don't want to write a site that is vulnerable.

Making a copy of an object
Hi, I have the following scenario: - I have retrieved an object from the database - I want to create another object based on this one, with minor modifications. What I'm doing is: - Get the existing object - Set its "id" to None - Modify any other fields and relations I need to - Save the object My question is, is it advisable to copy objects this way? Would there be problems with e.g. foreign keys and generic relations?

Flatpages not working on Apache+mod_python
Hello,
I am using Django 0.96 and I am currently having problems getting
flatpages middleware to work under Apache with mod_python. I am pretty
sure this is mod_python related since flatpages work fine using the
development server.
I have found at least one thread the mentions this problem, it's from
Aug 2006. The OP said he would take a look to see what the problem was
but did not post a follow-up.
http://groups.google.com/group/django-users/browse_thread/thread/eddadaacfc34aef9/194ee9abebecf6b6?lnk=gst=flatpages=5
The gist of it is that instead of rendering the flatpage it just keeps
rendering the 404 page when I run it on the production server.
However, using the development server flatpages work as expected. If
it helps any, I also have handler404 and handler500 point to a custom
handler.
below is the custom handler404:
def page_not_found(request):
c = getDefaultContext(request)
t = loader.get_template('404.thtml')
return HttpResponse(t.render(c))
Note I am using .thtml extension for templates only because Eclipse
with WTP chokes when editing Django templates.
getDefaultContext() above sets up the Context object containing
important variables used in the templates.
Can anyone here provide pointers on how to get flatpages to work
properly under Apache and mod_python?
One other thing... Is it possible to use Textile for flatpages too?
http://cheeseshop.python.org/pypi/textile
Thanks in advance.

Re: Adding fields dinamically to a model
Well, it turns out this would've been possible even without #4144, but now that it's in CVS, I wrote up a wiki article[1] on dynamic models, which should give you some clues on how to dynamically generate a model. For this case, it would suffice to use the generic approach listed there, created the field list dynamically, then creating the model with it. Be sure to use the same app_label as the current app, or you'll have problems with syncdb and admin. -Gul [1] http://code.djangoproject.com/wiki/DynamicModels On May 3, 12:56 pm, Mike Axiak <[EMAIL PROTECTED]> wrote: > Sandro, > > I'm not sure #4144 would help. > However, I think there are limits to what you can do with python > descriptors, and thus Django models.

Re: Pickle model fields
Turns out I decided to go with the Field class since I'll be needing them in a few different models. The issue I'm running into now is that the new field name isn't defined in the data_types list (from db/ backends/*/creation.py).

Where proper is anything to your liking, except the development server. If people are going to use this thing, you'll run in a lot more issues than the current one you're having.

Re: isolating karma score from comments
OK. My app is called "karma". The model looks like this:
from django.db import models
from django.http import Http404, HttpResponse
from django.contrib.contenttypes.models import ContentType
from django.contrib.auth.models import User
import datetime
class KarmaScoreManager(models.Manager):
def vote(self, user_id, content_type, object_id, rating):
try:
karma =
self.get(content_type__pk=content_type,object_id=object_id,user__pk=user_id)
except self.model.DoesNotExist:
karma = self.model(None, user_id=user_id,
content_type_id=content_type, object_id=object_id, score=rating,
scored_date=datetime.datetime.now())
karma.save()
else:
karma.score = rating
karma.scored_date = datetime.datetime.now()
karma.save()
def get_pretty_score(self, score):
"""
Given a score between -1 and 1 (inclusive), returns the same
score on a
scale between 1 and 10 (inclusive), as an integer.
"""
if score is None:
return DEFAULT_KARMA
return int(round((4.5 * score) + 5.5))
class KarmaScore(models.Model):
user = models.ForeignKey(User, related_name="karma_user",)
content_type = models.ForeignKey(ContentType)
content_object = models.GenericForeignKey()
object_id = models.IntegerField(_('object ID'))
score = models.SmallIntegerField(_('score'), db_index=True)
scored_date = models.DateTimeField(_('score date'), auto_now=True)
objects = KarmaScoreManager()
class Meta:
verbose_name = _('karma score')
verbose_name_plural = _('karma scores')
class Admin:
list_display = ('user', 'content_type',
'object_id','scored_date')
def __repr__(self):
return _("%(score)d rating by %(user)s") % {'score':
self.score, 'user': self.user}
And The view is:
from django.http import Http404, HttpResponse
from django.shortcuts import render_to_response
from django.template import RequestContext
from django.contrib.contenttypes.models import ContentType
from gretschpages.karma.models import KarmaScore
def vote(request, content_type, obj_id, vote, js=""):
ctype = ContentType.objects.get(model=content_type)
thisObject = ctype.get_object_for_this_type(pk=obj_id)
rating = {'up': 1, 'down': -1}.get(vote, False)
if not rating:
raise Http404, "Invalid vote"
if not request.user.is_authenticated():
return HttpResponse("Anonymous users cannot vote",
mimetype="text/html")
try:
obj = KarmaScore.objects.filter(content_type=ctype.id,
object_id=obj_id)
except:
raise Http404, _("Invalid comment ID")
if thisObject.id == request.user.id:
return HttpResponse("No voting for yourself", mimetype="text/
html")
KarmaScore.objects.vote(request.user.id, ctype.id, obj_id, rating)
if js == "js":
return HttpResponse(str(thisObject.get_karma_total()),
mimetype="text/html")
else:
return render_to_response('comments/karma_vote_accepted.html',
{'obj': obj}, context_instance=RequestContext(request))
Then, in the model of the thing you want karma for, you need these
helper functions:
def _fill_karma_cache(self):
"Helper function that populates good/bad karma caches"
good, bad = 0, 0
from django.contrib.contenttypes.models import ContentType

object_id=self.id):
if k.score == -1:
bad +=1
elif k.score == 1:
good +=1
self._karma_total_good, self._karma_total_bad = good, bad
def get_good_karma_total(self):
if not hasattr(self, "_karma_total_good"):
self._fill_karma_cache()
return self._karma_total_good
def get_bad_karma_total(self):

self._fill_karma_cache()
return self._karma_total_bad
def get_karma_total(self):
if not hasattr(self, "_karma_total_good") or not
hasattr(self, "_karma_total_bad"):
self._fill_karma_cache()
karma = self._karma_total_good - self._karma_total_bad
if karma < 0:
if karma < -3:
elif k.score == 1:
good +=1
self._karma_total_good, self._karma_total_bad = good, bad
def get_good_karma_total(self):
if not hasattr(self, "_karma_total_good"):
self._fill_karma_cache()
return self._karma_total_good
def get_bad_karma_total(self):
if not hasattr(self, "_karma_total_bad"):

Consequently - it will not find polls that have no choices, even if the search term is found in the question field, because the polls will not be in the join. - polls with multiple choices will be listed multiple times in the result if the search term is found in the question field, because the poll appears in the join once for each choice.

Re: Admin, edit_inline, and saving
It'd be helpful if you supplied us with a few more details: 1. What is MEDIA_ROOT and MEDIA_URL set to? 2. What is the Picture object's ImageField;s "upload_to" attribute set to? 3. Did you define your own "get_absolute_path(self)" method in the Picture model? 4. What version of Django are you running? 5. What server are you running Django through (Apache, built-in dev server, etc.) I'd assume that perhaps your MEDIA_ROOT or upload_to attributes are set incorrectly.

admin and custom filter
Hello there,
I have two models, Network and Address and have setup a filter (in the
admin interface, which I like) for Address, to show only free
addresses which works. I also have a filter on network, which works,
however this is not really dynamic, because if I have 2 networks
10.0.0.0/8 and 10.10.10.0/24, and address of 10.10.10.20 would be part
of both networks!
class Network(models.Model):
ip = models.CharField('IP', maxlength=15)
mask_len = models.PositiveIntegerField('mask length')
class Address(models.Model):
ip = models.CharField('IP', maxlength=15)
is_free = models.BooleanField('free')
network = models.ForeignKey(Network)
class Admin:
list_filter = ('is_free', 'network')
I now would like to have a similar filter in the Address part of the
admin interface, to display a list of all addresses that are part of a
network. From what I read/understood, I can setup a manager method,
but this requires also that I setup a view, template and more, and
then it would not even be integrated into the admin interface. Does
anyone have a idea on how to do this?
I hope I explained clearly enough what I would like to accomplish and
thank you for your input.

Re: How to set FORLOOP.COUNTER=0?
Ok then... So, actually I'm "plotting" tables with only 1 row and 15 columns, table below table. Often, when I change the subject I working with, there's a row that has less then 15 columns. Let's say the last line (table) had 2 columns. If the next line is in the "for" that created last line, the new one will contain 13 columns (and it should have 15). Was it clear? Sorry about my English. I'll try to improve it next time. Nice to meet you Malcolm! I read some reply you sent to a friend of mine. Regards, Renato.

Assuming low site concurrrency, no. I don't know why you'd want to
take that approach as opposed to having a cart model, but if it floats
your boat, go for it.
If you have high concurrency, just realize that session storage and
retrieval involves deserialization of the state bag out of the DB,
which is an additional overhead compared to general models, whose data
marshalling is performed by the (highly optimized) DB server and
client code. Your session table could also become a hot spot in the
DB since you'll be writing a larg-ish single row rather than many
smaller rows.

isolating karma score from comments
Hi, Neat design of the karma scoring application in the comments framework of the contributed application is quite appealing. But it is tided to the comments application. I am trying to isolate it and make a more generic karma application for any content (photos, blog entries, etc.) contributed by users.

I m currently building an e-commerce site and I was wondering if there
are any shopping cart apps out there for django that I can have a look

paypal but any ideas would be cool.
So far I am thinking of storing the whole shopping cart as a

is this a good way to proceed or do you believe there are some
problems with this approach?

Re: making custom exceptions like Http404?
Add a middleware class like this:
from django.http import HttpResponseForbidden
from django.template import loader, RequestContext
class Http403(Exception):
pass
class ForbiddenMiddleware:
def process_exception(self, request, exception):
if not isinstance(exception, Http403):
return
try:
template = loader.get_template('403.html')
context = RequestContext(request, {'message':
str(exception)})
return HttpResponseForbidden(template.render(context))
except:
pass # Let Django show the exception
Then you can throw a 403 simply by "raise Http403" in your view
functions.

Re: django vps hosting
I'm using a dedicated virtual at mediatemple. They're working on Django-containers, which would be a sweet feature if the ETA was anywhen soon. It's been easy to get django rolling, since you get a CentOS installation (a free clone of RedHat Enterprise). Yum is not installed by default, but a google gives you the right rpm's to get it up. I'm also writing up a post for my blog about this. It's fairly expensive (I pay $50/month for a (dv) base), but the support is awesome. I've been a pleased (mt) customer for years. Still... Apache gives me headaches over and over again. Once, after adding a virtual host, I got the same project displayed on all my domains/subdomains. Never got to figure out what the problem was.

Re: Maintainance Middleware

There isn't a way in a middleware to access some name path from the urlconf, is there? That way I wouldn't have to set those settings, by letting the admin-path bypass the maintenance middleware. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: geographical data in models
I didn't go with PostGIS because i only needed basic functionality and approximative data. In my models, i have : lat = models.FloatField(max_digits=7, decimal_places=4, blank=True, null=True) lng = models.FloatField(max_digits=7, decimal_places=4, blank=True, null=True) I'm using it together with GeoPy to find distances http://exogen.case.edu/projects/geopy/ For locations in a neighbourhood, i only use less and greater than on both fields. I'm also interested to see how others dealt with geolocation.

cloned admin behind apache proxy - firefox doesnot want to import base.css from login.css
Hello,
I cloned admin media and templates of django:
cp -a python-django/django/contrib/admin/media /opt/cedecka/app/
cp -a python-django/django/contrib/admin/templates \ /opt/cedecka/app/admin/
I customized a little templates (mainly title, ...).
The applications is started:
./manage.py runserver antares.site.xx:8000 \
--adminmedia=/opt/cedecka/app/media
(I setup template directory at /opt/cedecka/app/template).
The application runs at server inside internal network.
My goal is to have access to this application from internet.
I tried to set up proxy at www server:
...
RewriteEngine on
RewriteRule ^/(.*) http://antares.brailcom.xx:8000/$1 [P,L]
...
It works, but firefox does not want to load styles that are imported in
main style.
E.g. login.html loads login.css.
@import url('base.css');
@import url('layout.css');
/* LOGIN FORM */
body.login { background:#eee; }
.login #container { background:white; border:1px solid #ccc;
...
Firefox loads it but it neither tries to load base.css, layout.css.
I check by tcpdump plus tcptrace whether there is an attempt to load
them. No attempt. It ignores these import lines.
If I give firefox an url to load:
http://cedecka.pracovni.net/media/base.css, it loads it without problem.
If I made tunnel (ssh -L 8000:antares:8000 antares),
firefox loads all styles including imported ones.
IF I use IE, it loads all stylesheets and admin looks nice.
Firefox does not and admin is just textual (without any layout).
Please give me a hint to set up proxy/tunnel, for django application.
Thanks,
Jan Stavel

geographical data in models
Hi all, I am developing an application with django that requires some geographical data, both some points and tracks. I have some questions regarding the model design. I know Postgres and MySQL have geographic extensions. I have used MySQL's in the past but now I am mostly interested in Postgres. Should I design using those db extension? They provide some handy geographical calculations but maybe those should be better done in the views, not in the db. But, I guess, the indexing in the db will be optimized for geo data, which can improve the db performance. Also, using those extensions, points and tracks can all be defined as the same geo type column, which will allow me to store both points and tracks (list of points) in one single table. A workaround to avoid using geo specific db extensions but keeping data in one single table can be pickling the list of points and storing it, but I don't have much practical experience. My application will be using Google Maps API. The API supports a method of encoding point arrays which convert a track info into an ascii sequence. I may be storing this encoded data in a text field in the db. One more: Is the best way of defining a geographical point in a model defining lat / lng fields separately? Postgres has a Point data type. Can I use it in my models? I feel like avoiding db specific extensions and going with the basic model types would be the best. And ideas and experiences to share? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
