How to use lighttpd error-handler-404 handler to serve django?
I already have lots of static files in my lighttpd web server, so I'd like it to only talk to the django server if it can't find what it's looking for.

Re: Alternative to PIL (Python Imaging Library)?
Carlos,
If you need to get started quickly, you can use FileField instead of
ImageField, so the PIL won't be necessary. The requirements of the
uploaded image may be written in help_text. Maybe some validation of
the image width and height can be done using Javascript. I'm not sure
about that, you should check, whether it is posible to retrieve the
dimensions of the selected file through Javascript, writing something
like that:
oImg = new Image();
oImg.onload = function() {
alert(oImg.width + "x" + oImg.height);
}
oImg.src = document.getElementById("fileUploadFieldId").value;
(The script is written on the fly, I am not sure whether it works correctly)
Good luck!

Argh, bad news. Actually I asked the question because I'd like to use custom SQL in a 'limit_choices_to' option, in the admin interface.

if that's all you need, you don't really have to compile PIL.
just copy the contents of the "PIL" directory to some suitable location
on your path, and you get a PIL install that can identify and open most
image formats (you'll get errors if you're actually trying to do
something with the pixels, though).
example:
>>> from PIL import Image
>>> im = Image.open("Images/lena.jpg")
>>> im.mode
'RGB'
>>> im.size
(128, 128)
>>> im.load()
Traceback (most recent call last):
File "", line 1, in ?
File "PIL/ImageFile.py", line 217, in load
return Image.Image.load(self)
File "PIL/Image.py", line 607, in load
return self.im.pixel_access(self.readonly)
AttributeError: pixel_access

How about ordering by a ForeignKeyField?
snippet follows:
class Model(models.Model):
opis= models.CharField(maxlength=50)
znamka = models.ForeignKey(Znamka)
def __str__(self):
return "%s %s" % (self.znamka, self.opis)
class Admin:
list_filter = ['znamka']#
sidebar with handy filters
class Meta:
verbose_name_plural = "Modeli"
ordering = ['znamka', 'opis']
In the memorable words of Dr. Jones... "this doesn't seem to work" =)

Re: admin ordering question
I solved it!
The problem was because I was trying to sort by a field that was not
listed on Admin.list_display
Updated code:
class Model(models.Model):
opis= models.CharField(maxlength=50)
znamka = models.ForeignKey(Znamka)
def __str__(self):
return "%s %s" % (self.znamka, self.opis)
class Admin:
list_filter = ['znamka']#
sidebar with handy filters
list_display = ('znamka', 'opis')
class Meta:
verbose_name_plural = "Modeli"
ordering = ['znamka','opis']
Like a charm, it works.

Image auto resizing
Hi, I'm trying to resize an image automatically after the upload. Maybe Django should have this by default, but until there I'll try myself... I got it working sucessfully, but I don't know if this is the best way, the image is processed every time I save the object, it should be done only on new uploads. My model: class pic(models.Model): name = models.CharField(maxlength=60, core=True) pic = models.ImageField(upload_to='news') def save(self): file_path = self.get_pic_filename() # There's is a file? if (file_path): im = Image.open(file_path) # Using my own image resizing based on PIL im = image_util.best_fit(im, 30, 30) im.save(file_path) super(news_pic, self).save() class Admin: pass Is there a better way to do it? How hard would be to create a "custom" ImageField for this? It could be used in many other models in my project, and could even get included in the Django package. Thanks in advance.

Camino and Safari do not open feeds
Hi group,
I implemented a feed as described in
http://www.djangoproject.com/documentation/syndication/.
The source can be found here: http://paste.e-scribe.com/703/
The url configuration is:
(
r'^feeds/(?P.*)/$',
'django.contrib.syndication.views.feed',
{
'feed_dict': { "latest" : LatestEntries}
}
),
If I point Safari to the url, I get a "Don't understand content" error.
Camino just saves the file to the download folder. The structure and
everything of the file ( := the feed) is as intended. But I want Safari
and Camino and all the other browsers to recognize the feed as a feed.
Anyone has had similar experiences?
Regards,
-Justin

The important thing is that Python be able to find and use it. I think you can download the .deb, then do something like this: dpkg -i -instdir=/some/path/under/your/home your.deb from the man page: --root=dir | --admindir=dir | --instdir=dir Change default directories. admindir defaults to /var/lib/dpkg and contains many files that give information about status of installed or uninstalled packages, etc. instdir defaults to / and refers to the directory where packages are to be installed. instdir is also the directory passed to chroot(2) before running package's installation scripts, which means that the scripts see instdir as a root directory. Changing root changes instdir to dir and admindir to dir/var/lib/dpkg. Since you'll be installing to a non-standard location of PIL, you'll need to make sure it's on the path (and on Python's path, which I think you can do with SetEnv in your apache conf), and then (I think) you should be set. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Setting up Django on Archlinux with MySQL backend

Please fix my ugly code
Hello people, my ongoing adventures in firstdjangoappland continue thus:
I'm putting together a simple search app for a car project. On entry,
user sees a list of 5 random cars. He can use up to two comboboxes to
filter the results (car model and fuel type).
This is what I've come up with on my home() view, so far, and it looks
really ugly.
def home(request):
results = {}
# these 2 guys are the filters
model_list = Model.objects.all()
gorivo_list = Gorivo.objects.all().order_by('opis')
selected_model_id = 0
selected_gorivo_id = 0
if request.POST:
# this handles 'SELECTED' attribute on comboboxes
try:
selected_model_id = int(request.POST['model_id'])
except:
pass
try:
selected_gorivo_id = int(request.POST['gorivo_id'])
except:
pass
# and this should take care of the filtering... but I'm stumped
really
# both filters should add up
results = Vozilo.objects.all()
if selected_model_id != 0:
results =
results.filter(model_id__exact=selected_model_id)
if selected_gorivo_id != 0:
results =
results.filter(gorivo_id__exact=selected_gorivo_id)
else:
# no POST, we show 5 random cars.
results = Vozilo.objects.order_by('?')[:5]
return render_to_response('cars/home.html', {
'model_list':model_list,
'gorivo_list':gorivo_list,
'selected_model_id':selected_model_id,
'selected_gorivo_id':selected_gorivo_id,
'results': results
})
There must be a better way of doing this, right? I'm a terrible newbie
both at Python and Django --and I'm not a kid anymore, so no more time
to spare hitting my head on walls :-)
Insights? Ideas?
Thanks a million,

Hi. Are you running the development server?
I've found these don't tend to work in the development server in
Safari, but you when you make sure app live at a 'proper' url they
will work.

SQL Queries with columns not in the DB
I'm reposting this because I was told my last post got lost in an existing thread. Sorry about that. I figured out my syncdb question. It turns out that as long as the model is defined correctly things go well. And the output from syncdb will help you with any trivial troubles you might have with your model. Nice! Another question for you all. I want to duplicate the queries that the existing app does. The site maintains the results, standings, and stats for a baseball league. It has queries like: select number, name, win, loss, tie, streak, streak_type, win/(win+loss+tie)*1.000 wpct, win*2+tie points, win+loss+tie GP, gamesinseason.games - (win+loss+tie) GL from stand_overall, gamesinseason, team where team.year = %s && gamesinseason.year = team.year && stand_overall.team = team.ID order by points desc, win desc, tie desc, loss and select First_name, Last_name, sum(ab) ab, sum(runs) r, sum(1b) s, s um(2b) d, sum(3b) t, sum(hr) hr, sum(hbp) hbp, sum(bb) bb, sum(ko) ko, sum(1b+2b+3b+hr) hits, (sum(1b)+sum(2b)+sum(3b)+sum(hr))/sum(ab)*1. avg, sum(bb)/(sum(bb)+sum(ab))*1. bb, (sum(1b)+sum(2b)+sum(3b)+sum(hr)+sum(bb)+sum(hbp))/(sum(ab)+sum(bb)+sum(hbp))*1. ob, (sum(1b)+2*sum(2b)+3*sum(3b)+4*sum(hr))/sum(ab)*1. as slug, sum(runs)/(sum(1b)+sum(2b)+sum(3b)+sum(hr)+sum(bb)+sum(hbp))*1 . score, sum(ko)/(sum(ab)+sum(bb)+sum(hbp))*1. kperapp from player, offensive_stats, game where player.ID = offensive_stats.player && game.ID = offensive_stats.game && player.First_name = %s && player.Last_name = %s group by First_name, Last_name My question revolves around how I should get similar results in django. From what I can tell I should be subclassing a Manager so I can return my own QuerySets. I don't think the writing custom SQL with connection.cursor() is the way to go. I know that the join portions of the where clauses will be taken care of by the db_api. I also know that I can do ORDER BY and LIMIT type stuff with extra=, .order(), etc. Am I on the right path? -- | Jason Murray -- | The problem in living with popular culture is maintaining some degree of | individuality - some sense of who we are and what we think in a world | in which so many others are trying to determine those things for us. -- Gary Bauslaugh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Hi Justin, I believe this is happening because Django uses the "application/atom+xml" MIME type for Atom feeds, and your browsers don't appear to be able to handle that MIME type. In the grand scheme of things, this is no problem, but if you really want to be able to see the raw source of your feed, change your browser settings to use a particular program to handle that MIME type.

Re: Django Blog Code
I get an attibute error and a template error when I try to view the
detail of a post:
'NoneType' object has no attribute '_default_manager' is the attribute
error.
{% free_comment_form for blog.entry object.id %} is highlighted as an
error in the template.
Can you give me some idea of where to start looking to correct these
errors? I have a feeling it is in the models.py somewhere, but I'm
using the exact same code as from the url you provided.

Re: Please fix my ugly code
Hi Carlos,
I think your code is going good so far. Of course I'm not a guru but I
think your code is fine. Is there something that you don't feel
comfortable with? With respect to adding the results of both filters,
you need to extend the results of the first results (if any), like
this:
results = Vozilo.objects.all()
if selected_model_id != 0:
results = results.filter(model_id__exact=selected_model_id)
if selected_gorivo_id != 0:
results.extend(results.filter(gorivo_id__exact=selected_gorivo_id))
If I were to code that view I would use a custom manipulator and it
would end up something like the following. But PLEASE, PLEASE, be
aware that it's just my personal way of doing things, I am no one to
tell you how to do things.
class FilterResultsManipulator(forms.Manipulator):
def __init__(self):
model_choices = [(m.id, m) for m in Model.objects.all()]
gorivo_choices = [(g.id, g) for g in
Gorivo.objects.all().order_by('opis')]
self.fields = (
forms.SelectField(field_name='model', choices=model_choices),
forms.SelectField(field_name='gorivo', choices=gorivo_choices),
)
def home(request):
results = []
filter_manipulator = FilterResultsManipulator()
filter_data = {}
if request.POST:
filter_data = request.POST.copy()
model = None
gorivo = None
if filter_data.get('model'):
model = get_object_or_404(Model, pk=filter_data['model'])
if filter_data.get('gorivo'):
gorivo = get_object_or_404(Gorivo, pk=filter_data['gorivo'])
if model:
results = Vozilo.objects.filter(model=model)
if gorivo:
results.extend(Vozilo.objects.filter(gorivo=gorivo))
else:
results = Vozilo.objects.order_by('?')[:5]
filter_form = forms.FormWrapper(filter_manipulator, filter_data, {})
return render_to_response('cars/home.html', {
'results': results,
'filter_form': filter_form,
})
And the template you only need to display the form fields.
Search by:
Model: {{ filter_form.model }}
Gorivo: {{ filter_form.gorivo }}
The custom manipulator and associated form wrapper takes care of
displaying the select fields in your form and maintaining the selected
option between posted pages. The use of the utility
get_object_or_404() frees you of worrying if the incoming data is
invalid or malformed, if it is a 404 exception will be raised and the
user will get a 404 page.
If you have questions about the above code feel free to ask.
Cheers,
Jorge

Re: Please fix my ugly code
Hi again Carlos,
I suggested this change in your code:
> results = Vozilo.objects.all()
> if selected_model_id != 0:
> results = results.filter(model_id__exact=selected_model_id)
> if selected_gorivo_id != 0:
> results.extend(results.filter(gorivo_id__exact=selected_gorivo_id))
>
But I'm totally wrong there. Your original code should be fine,
because you were chaining the filters. The 'extends' is not necessary
and in fact it is wrong.
I also realized that the filter logic in the code that I proposed is
wrong. With that code you would get a list of cars that match the
specified model, along with all the cars that match the gorivo type
(regardless of model).
The correct thing is to chain the filters like you did in your
original code. This should work, I tested it with a model I have here.
results = Vozilo.objects.all()
if model:
results = results.filter(model=model)
if gorivo:
results = results.filter(gorivo=gorivo)
I'm sorry if I caused any confusion and for not paying more attention
to that filtering part :)
Cheers,
Jorge

Re: Non iterable argument
Hi,
You are calling manipulator.do_html2python() before the call to
get_validation_errors()
The correct thing is to call do_html2python() after you have validated
the data and there are no errors.
It should look like this:
errors = manipulator.get_validation_errors(new_data)
print errors
if not errors:
print "noerrors"
manipulator.do_html2python(new_data)
print new_data['owner']
Cheers,
Jorge

Problems with __str__ methods in my Models
Yes it's me again :)
Anyway I've populating my Models with __str_ methods. I've only had on
hicough.
Here is the model in question:
class Result(models.Model):
ID = models.IntegerField(primary_key=True)
home_runs = models.IntegerField("home team runs", null=True, blank=True)
away_runs = models.IntegerField("visiting team runs", null=True,
blank=True)
game = models.ForeignKey(Game, db_column='game')
ump1 = models.ForeignKey(Ump, related_name='result_ump1',
db_column='ump1')
ump2 = models.ForeignKey(Ump, related_name='result_ump2',
db_column='ump2')
def __str__(self):
return "%s: %i (%i)" % (self.game.datetime.strftime("%Y-%m-%d"),
self.game.away.number, self.away_runs)
class Meta:
db_table = 'result'
class Admin:
pass
When I jump into the shell (python manage.py shell) to try it out...
>>> Result.objects.all()
Traceback (most recent call last):
File "", line 1, in ?
File
"/usr/local/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/query.py",
line 88, in __repr__
return repr(self._get_data())
File
"/usr/local/lib/python2.3/site-packages/Django-0.95-py2.3.egg/django/db/models/base.py",
line 76, in __repr__
return '<%s: %s>' % (self.__class__.__name__, self)
File "/home/jmurray/prfa/../prfa/standings/models.py", line 88, in __str__
return "%s: %i (%i)" % (self.game.datetime.strftime("%Y-%m-%d"),
self.game.away.number, self.away_runs)
TypeError: int argument required
However when I retrieve an individual result...
>>> r=Result.objects.get(pk=234)
>>> r
>>>
This is confusing to me. __str__ works for an individual objects, but not
a collection of them. What's happening here?
I'm puzzled, I hope someone here is able to help me out.
BTW it is self.away_runs that causes the problems. When I remove that from
the __str__ function it works just fine.

Based on the settings file here:
http://code.djangoproject.com/svn/djangoproject.com/django_website/settings.py
They're using the django.contrib.comments app, which defines the
free_comment_form template tag. django.contrib.comments is included
in your django distro, though it's not documented yet. You should be
able to just add comments to your INSTALLED_APPS and sync your DB.
http://code.djangoproject.com/svn/django/trunk/django/contrib/comments/
If you want to understand how to use the comments app, browsing the
source and documenting what you be a fine way to learn it. ;-)

Re: django for end users?
thanks for the response eas. I have seen and tried to install some of the django blog apps people have shared but without success (so far). I guess the message here is that there is just no way around setting some time aside to sit down and learn how the pieces go together, that it is not for end users (perhaps post 1.0...)...it IS called a "framework" after all. :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

This is happening because at least one of your Result objects has an
away_runs field with a value of None. The "%i" string formatting
parameter accepts only integers; if you feed it None, you'll get that
exact error. Try this at the Python interactive prompt:
print '%i' % None
The solution is to either use '%s' instead of '%i', or to special-case
the case in which self.away_runs is None. Example:
def __str__(self):
if self.away_runs is None:
away_txt = 'No away runs'
else:
away_txt = str(self.away_runs)
return "%s: %i (%s)" % (self.game.datetime.strftime("%Y-%m-%d"),
self.game.away.number, away_txt)

Sorry :-( Actually there is another solution. You can create a custom Q class (the "Q" class is defined in django.db.query). The get_sql() method of your class has to return something in the right format, so it requires understanding the return results from django.db.query.parse_lookup(). It's not too hard to work out (putting a print into Q.get_sql() and running one should be enough of a start).

If you are wanting to use aggregates in the select clauses, then you need to write custom SQL to some extent. The extra() method on QuerySets will help you with some of this, since you can inject extra things into the select clause that way (see the DB API documentation examples). Unfortunately, the "group by" clause sinks you. You cannot do grouping with query sets (at the moment, at least). So you are back to writing custom SQL for those.

Hi Iain. in your apache config do something similar to http://svn.zyons.python-hosting.com/trunk/zilbo/conf/zyons.conf.tmpl and that will let the apache handle the 'images' area of your site instead of django.

Samples for displaying a tree of data
I'm using the recipe here (http://code.djangoproject.com/wiki/CookBookCategoryDataModelPostMagic) for a category model. It's working well for the most part. I am getting a little stuck trying to figure out how to turn it into a vertical navigation structure. I've looked at http://code.djangoproject.com/wiki/ModifiedPreorderTreeTraversal but I think this is not as nice from an admin perspective so I'm not using it. My category structure might look like books :: non-fiction :: technical :: Django for Dummies How can I create some sort of menu structure like I've shown below? Books ->Non-fiction ->History ->Biographies ->Technical ->Fiction Movies Games I'm a little worried that all the recursion could get painful from a performance perspective & I figure this is a common enough situation that maybe someone else already has something that works pretty well.

It's not too bad to do the obvious thing. I do something similar in the sidebar of http://www.pointy-stick.com/blog/ and on http://www.pointy-stick.com/blog/topics/ . I'm not nearly as cool as Ian Holsman, so I don't have a version control respository online. You can grab the source code from http://www.pointy-stick.com/software/website-latest.tar.gz and have a look, though. It's basically the recursion approach you are talking about. Performance isn't too bad for "reasonable" levels of nesting. Start at weblog/templatetags/mt_weblog.py (TagCloud.render, in particular) and work back to the Tag model. Once we get model-aware validators in place, I intend to switch to using a slightly different encoding for tag sub-trees, as mentioned in the comments in weblog/models.py, so I haven't worked too hard on making this neat and spiffy yet as the "extract all tags" portion can be done in a single query with a slightly different model setup.
