It looks like, in your lighttpd config, /media/* is mapped directly to the filesystem. That's why it's not going through Django's URL config when you use the /media/* URLs.

Re: Can Django be combined with a more powerful ORM?
I had some success mapping SQLAlchemy Table objects to django models, but as
Malcolm said if you're starting from scratch, unless you have a really
compelling reason to use django models, why not use SA directly?
Also, and forgive the tone of this, it's not meant to sound rude, why do you
want to stay close to original code that looks like this:
>p[d[series][game]["f"][ixb]["owner"]]["kills"]++;

Re: Using the DB Package Outside of Django
Thanks for the help. A little tip for anyone else who wants to do this: put models.py in a package.

Re: Serving large files through HttpResponse
If using mod_python, you might also look at Tramline: http://infrae.com/products/tramline This allows a response to set a special header which is then picked up by an Apache output filter, with the output filter then inserting the file contents direct into the output stream. Using Python to do this sort of Apache filter will still incur some overhead, but better than sending the file yourself. I imagine there must be a C module for Apache for doing this sort of stuff as well which would make it even more efficient.

Using the DB Package Outside of Django
I've used the template engine of Django in many scripts and I was wondering if there's a simple way of doing the with django.db package. I've already invested a lot of time learning Django's DB API and really like it so it would be great if I can make a models.py file and use those classes in my scripts instead of having to resort to SQL. I've looked around and haven't found anything on it. Is there a quick way of creating a settings.py file and calling Django's DB API to connect to the database and start using my models?

ugettext vs. ugettext_lazy
Hello,
I've been playing with these functions and finally I've become totally
confused.
I've expected that there would be some difference in behaviour, but I
was not able to create such use case in which these two functions
produces different results. More precisely, I haven't find place where
would be better to use ugettext_lazy. In documentation is said to use
this function in models.py everywhere. But for me it looks that ugettext
makes the same work. All text marked to translation is translated
accordingly to locale set by user via browser with both of them.
Furthermore i was not able to use template strings and stay in __proxy__
mode. anything like ugettext_lazy('xyz %s') % 'some_text' comes to
unicode string representation immediately. So, it looks there is no way
to use template strings with *_lazy. From my view it is little bit
painful to use it.
But I think I must be completely missing something important in this
area. Can anybody enlighten me, please?

Odd behavior of filtering
Hi My model is: class Tag(models.Model): name = models.CharField(maxlength=30) class Snippet(models.Model): name = models.CharField(maxlength=30) tags = models.ManyToManyField(Tag,filter_interface=models.HORIZONTAL) My aim to filter snippets according to multiple tag constraints simultaneously. However, the overlap of two sets just doesn't get filtered properly.

db-api optimization
Hello, I'm preparing a search form to perform searches against the db (Postgre ). well, Imagine the form with a category field, and a words field. My view is something similar to this: def my_view( request ): items = a_model.objects.all() if request.GET: ... if form.is_valid(): ... words = data['words'].split() for word in words: items = items.filter( title__icontains = word) items = items.filter( description__icontains = word) if data['category']: items = items.filter( category = data['category'] ) Well, I know that since full-text is not available, this way is quite intensive for the db.This code, search the words in the title and the description, and if the category is defined, refines the result to that category, if not, all categories are shown. I have read in the docs, that chaining filters doesn't hit the database. Is this a good way of chaining filters or perhaps there is other more effective? Is there any way I can see the final generated sql clause? Thank you! (I'm really looking forward to postgre 8.3 with full-text in the core) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Float Field not displaying the two zeros at the end of a price
Jake and Zerek, I will able to fix the problem thanks to your suggestions. It turns out that instead of using 'a.price' I have to use 'a.price.name'. Below is my model code: class Price(models.Model): name = models.DecimalField(max_digits=6, decimal_places=2) price_cat = models.ForeignKey(PriceCategory) def __str__(self,): return str(self.name) class Admin: pass class Choice(models.Model): choice = models.ForeignKey(Collection, edit_inline=models.TABULAR, num_in_admin=5) size = models.ForeignKey(Size, core=True) price = models.ForeignKey(Price, core=True) / My for loop in my template contained all of my choices that fit the criteria. Notice how 'price' is a ForeignKey to the Price class. We'll when I did a 'a.price' I guess that was returning a string based on 'def __str__(self,): return str(self.name)'. So in my template I changed it to a.price.name and it works. The two zeros now appear.

Re: Odd 404 error on Textdrive with Lighty
Hi Dave, > line 72, in find_template_source > raise TemplateDoesNotExist, name > TemplateDoesNotExist: 404.html This is really saying that you do not have a 404.html template defined. Just create a simple 404.html file at the base of your template dir path and add a simple message to it. This won't solve the problem of why you are getting that 404 error in the first place, but at least you won't be distracted by the confusing message. Also, it's likely that the request is never matching any of your URL conf patterns causing the 404 error. So, perhaps post another message here detailing all urls.py that come into action during this particular request. -Rajesh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Odd 404 error on Textdrive with Lighty
I have textdrive account with lightty and flup running. The blog section works great. No problems. However, the audio media (and I suspect other elemets of the same app) generic views are throwing an odd 404 error. It seems that the system is not getting to the django debug. However, it is showing that I do not have a template in place. Which, you guessed it, I do. Here is the log entry: 2007-08-20 15:52:38: (mod_fastcgi.c.2551) FastCGI-stderr: Traceback (most recent call last): File "/users/home/stpauls/local/flup/server/fcgi_base.py", line 558, in run protocolStatus, appStatus = self.server.handler(self) File "/users/home/stpauls/local/flup/server/fcgi_base.py", line 1112, in handler result = self.application(environ, start_response) File "/users/home/stpauls/local/django_src/django/core/handlers/wsgi.py", line 189, in __call__ response = self.get_response(request) File "/users/home/stpauls/local/django_src/django/core/handlers/base.py", line 103, in get_response return callback(request, **param_dict) File "/users/home/stpauls/local/django_src/django/views/defaults.py", line 78, in page_not_found t = loader.get_template(template_name) # You need to create a 404.html template.

how to change admin output of fields in editmode?
i want to change how fields are displayed in admin mode in the edit view. for example: if i use a ImageField, on editmode it says: > Derzeit: images/2007/08/17/preview/preview1.png but i want it to display the image, instead of the path and a link to the image how would one do that? is there a method which manages the output of the admin edit mode which i could overwrite? thanx for any help --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Dynamically changing newforms
Hello group,
I'm trying to build a fairly complicated form submission using
newforms, which requires that the form is modified based on
information in the model.
For example, I've got a couple of models which look like this:
class Question(models.Model):
questionText = models.CharField(maxlength=255,
verbose_name="question text")
classification = models.ForeignKey('Classification')
exampleAnswer = models.CharField(maxlength=255,
verbose_name="example answer")
required =
models.BooleanField(verbose_name="compulsory question?")
class Answer(models.Model):
question= models.ForeignKey('Question')
classification = models.ForeignKey('Classification')
job = models.ForeignKey('Job')
answerText= models.TextField()
The basic premise is that each Classification has a set of Questions
associated with it, some of which are required. So the form is really
simple - there's only one editable field so the user can answer the
question:
class QuestionAnswerForm(forms.Form):
text = forms.CharField(widget=forms.Textarea, help_text="replace
me with the example answer", verbose_name="replace me with the
question")
I'd like to set the verbose_name on that CharField to be the question
to be answered, and the help_text to be the example answer; similarly
for whether the field is required or not. This can be done by
modifying form.fields['fieldname'], but unfortunately the changes
don't remain after the forms have been POSTed, which I think is
because the form is rebuilt from the POSTed information.
You can also modify form.base_fields, but those changes are applied on
a class-wide (as opposed to per-instance) basis, which doesn't help me
because I have multiple Question forms on each page.
Short of including the extra context information (example answer,
required etc.) inside the form in hidden fields, I'm stuck.
Can anyone suggest a better way of doing what I'm trying to achieve?
Many thanks,
Matt.

Re: Can Django be combined with a more powerful ORM?
You can minimize the amount of code writing some special methods for
your Player model, i.e.:
player = Player.objects.get(...)
player.increase("kills", 1)
where
class Player(..):
...
def increase(self, attribute, by_value):
current_value = getattr(self, attribute, 0)
setattr(self, attribute, current_value + by_value)
self.save()
Good luck!

Re: (1040, 'Too many connections')
Hi guys, First, thanks for the great help. I read your recomendations and fall on 2 solutions: 1) Upgrade django to version 0.96. I see some people run into problems with mysql (postgresql too), the recomended revision is [5511]. I don ´t work on this project (the site I´m keeping) from the starting, I got it in the middle. It seems my django checkout is [3754] from 2006-12-09. On the same thread, the problem seems to be raised on the [5482] django release, this way I think the problem isn´t with my django instalation. I didn´t upgraded my django version because I planning to upgrade/rewrite my whole project using newforms/newforms-admin, I don ´t know if there will be any side effect migrating to 0.96, so I focused my efforts to another points. Anyway, running a `mysqladmin proc` tells that the connections are closed properly, almost anytime I run the command, it shows me only the mysqladmin connection. 2) Upgrade MySQLdb lib. I had problems with newer versions of this lib (problems with unicode), I used webware+sqlobject. Do you think this will really solve my problem? I just wonder if I will solve a problem and raise another one (with character encoding :-P) Thanks for all help!

how to change admin output of fields in editmode?
i want to change how fields are displayed in admin mode in the edit view. for example: if i use a ImageField, on editmode it says: > Derzeit: images/2007/08/17/preview/preview1.png but i want it to display the image, instead of the path and a link to the image how would one do that? is there a method which manages the output of the admin edit mode which i could overwrite? thanx for any help --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: how to change admin output of fields in editmode?

Unicode question
After moving to the latest version of Django one of the functions I
wrote fails to work.
I'll drop the code...
def year_cal(sectie, req_year = None, req_month=None):
cur_year= str(datetime.datetime.now().year)
cur_month= datetime.datetime.now().strftime("%b")
all_month_list = ['jan', 'feb', 'maa', 'apr', 'mei', 'jun', 'jul',
'aug', 'sep', 'okt', 'nov', 'dec']
month_list = []
if req_year is None:
req_year = cur_year
req_month= cur_month
else:
if int(req_year) > int(cur_year):
req_year = cur_year
if req_month is None:
req_month = trans_month('jan')
else:
req_month = trans_month(req_month)
prev_year_url = sectie.get_absolute_url() + str(int(req_year) - 1)
+ '/' + req_month
next_year_url = sectie.get_absolute_url() + str(int(req_year) + 1)
+ '/' + req_month
if int(req_year) == int(cur_year):
next_year_url = False
toggle_latest = False
for month in all_month_list:
if trans_month(month) == str.lower(req_month):
current = True
else:
current = False
if trans_month(month) == str.lower(cur_month):
url = sectie.get_absolute_url() + str(req_year) + '/' +
month
toggle_latest = True
else:
if(toggle_latest):
url = False
else:
url = sectie.get_absolute_url() + str(req_year) + '/' +
month
month_dict = {
'url' : url,
'caption' : month,
'current' : current,
}
month_list.append(month_dict)
else:
for month in all_month_list:
url = sectie.get_absolute_url() + str(req_year) + '/' + month
if trans_month(month) == str.lower(req_month):
current = True
else:
current = False
month_dict = {
'url' : url,
'caption' : month,
'current' : current,
}
month_list.append(month_dict)
return {'prev_year_url': prev_year_url, 'req_year': req_year,
'next_year_url': next_year_url, 'month_list': month_list }
register.inclusion_tag('year_cal.html')(year_cal)
The first error I get is about the line
str.lower(cur_month)
because str expects a str but gets a unicode.
Can some of you please give some simple tricks about moving from str
to unicode?

Manytomany relation with additional data
Hi all!
I think the subject is self explaining.
I already know in this case I need to define an intermediary table
with two foreign keys and the needed additional fields.
Let's imagine this situation:
1) a product table
2) an ingredient table
3) need to link many ingredients (with its percentage) to a single
product
For example:
Product table contents:
- bread
- biscuit
Ingredient table contents:
- flour
- water
- salt
- sugar
- butter
Product - Ingredient table contents:
- bread - flour - 50%
- bread - water - 49%
- bread - salt - 1%
- biscuit - flour - 45%
- biscuit - sugar - 35%
- biscuit - butter - 20%
The problem is that you cannot say that one table is "more important"
than the other one. For example in this case I would like to choose a
product ("bread") and insert all ingredient ("flour", "water", "salt")
with each percentage. Moreover I would like to see and/or edit all the
ingredients for one product in a tabular way to check that all
percentages sum up to 100 (not more not less).
Any ideas or hints?
Thanks.
Ciao.
Marco.
P.S. I imagine this is an hell to manage so at least I would like to
be able to pre-populate product field with the last product inserted.

Re: url issue giving me grief
well, according to the tutorial i am following
(r'^polls/$', 'mysite.polls.views.index'),
should not work either. Cause in the tutorial mysite is the project
and polls is the application. Just like with mine where Social is the
project and network is the application.

It tells you right there in the error message. You have only configured
your url patterns to look for things starting with network, accounts or
admin. So passing it a URL starting with "index" isn't going to match
anything. Why do you expect those requests to return anything?

Malcolm

url issue giving me grief
I am going through the tutorial from the site, however I have named
my files a bit different. My project is named Social and my
application is named Network.
settings.py
ROOT_URLCONF = 'social.urls'
TEMPLATE_DIRS = (
"C:/python25/scripts/social/network/templates/admin",
"C:/python25/scripts/social/network/templates/registration",
urls.py
from django.conf.urls.defaults import *
urlpatterns = patterns('',
(r'^network/$', 'social.network.views.index'),
(r'^accounts/', include('registration.urls')),
(r'^admin/', include('django.contrib.admin.urls')),
)
Now, when i go to http://127.0.0.1:8000/blog or http://127.0.0.1/index/
I get the following error message.
Request Method: GET
Request URL:http://127.0.0.1:8000/index/
Using the URLconf defined in social.urls, Django tried these URL
patterns, in this order:
1. ^network/$
2. ^accounts/
3. ^admin/
The current URL, index/, didn't match any of these.
Anybody have any ideas on what I might be doing wrong?
I have gone over this, and talked about in #django on IRC, no one has
any ideas what I am doin wrong here.
Thanx,
Dave

Should it really be "name"? You refer to "price" in your template...

Can Django be combined with a more powerful ORM?
As a side-project I tried to port Stellar Crisis 2.2 (a 15 year old browser game written in the C-like langage Pike for the Roxen server) to Django. So far, unfortunately, I failed. It seems, Django isn't the right tool to create such kind of application :( SC keeps all persistent data two global dicts that contain other dicts containing more dicts and arrays. I tried to map the data onto database tables but doing this, most of the elegance of Python seems to vanish. My code is actually worse than the original Pike code. Here's an example (Pike): p[d[series][game]["f"][ixb]["owner"]]["kills"]++; "p" is the global dict of players (all player data are kept in another dict). "d" is the global dict of all other game data. Games are instances of series and "f" probably means fleet and stands for a dict of all ships. A ship is owned by a player and the server stores how many other players a player has beaten. The Django equivalent seems to be: g = Series.objects.get(name=series).game_set.get(no=game) p = Player.objects.get(name=g.fleet_set.get(no=ixb).owner) p.kills += 1 p.save() I want to stay close to the original source code (even if I do not consider it the best style) to make porting the code more straight forward. Therefore, I added helper methods to the models so that I can use [] to access a series' game. The resulting code looks like is: player = p[d[series][game].f(ixb).owner] player.kills += 1 player.save() However, I still need three lines of code where the original just used one line because I have to explicitly save the state change. The original Pike code contains all game logic in one very large function (~800 lines of code) that does a lot of modifications. Adding explicit save() methods all over the place seems to be a bad (and inefficient) way to add persistence. I'd like to freely modify database objects once loaded into memory and then put everything that was modified with just one command back to the database. Most ORMs work that way, I think. Objects are loaded once within a transaction, know whether they are modified, dependent objects can be automatically added or deleted and all modifications of the database take place in one bulk operation at the end of the transaction. Has anybody extended Django's ORM in such a way? Can it be replaced with some other mapper? I recently heard about Storm, a new mapper written by the Ubuntu guys... I'd prefer to not have to write my own ORM. I've done that more than once in other language :) My ad hoc idea is to add a __setattr__ method to all models after their post_init signal and that method would register the model object as modified with some transaction context. However, because Django's ORM doesn't honor object identity, things get very inefficient very soon. I'd also need to overwrite delete() to make sure that I do not save deleted objects. But then, it seems that each time I ask a game for its fleets or systems, a new database query is executed and I have to cache them manually and reset the cache manually if I add new ships or systems. I'm afraid, I over-bend Django's ORM here... -- Stefan Matthias Aust --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Float Field not displaying the two zeros at the end of a price
Jake,
I've made the change to where both of my fields are now of type
DecimalField. However, I'm getting the same error:
TypeError

Caught an exception while rendering: float() argument must be a string
or a number

Here is what I have is my models file:
models.DecimalField(max_digits=6, decimal_places=2)

Thanks

Serving large files through HttpResponse
I'm serving rather large, static files through Django. I'd rather not use renaming trickery to serve them, but I don't know what the best way to serve them through HttpResponse is. I used to use this: response = HttpResponse(iter(open(file_path, "rb"))) return response in my view. That stopped working in the previous week or two. I'm not sure why, exactly. Is this method no longer supported? I am not even sure if it is doing what I hoped it was doing. =) The only other option I see to serving large files securely is trickery using dynamically created sym links to the true static file and then redirecting the user to those URLs and letting Apache serve them. This isn't as secure, though, and permits multiple downloads without them being recorded in my Django apps. The files range in size from a few hundred KB up through about 50 MB, mostly hefty print-ready PDFs. Any suggestions? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

That is quite a lot of memory being used before anything actually happens, although not entirely clear whether you are stating the whole virtual memory of the processes or only resident memory. > I have both mod_php and mod_python loaded.

Do you know whether your Apache web server is compiled with --enable- threads? Running: httpd -V may or may not tell you. Is your Python compiled with threads? You can tell by trying to import 'threading' from interpreter. $ python Python 2.3.5 (#1, Mar 20 2005, 20:38:20) [GCC 3.3 20030304 (Apple Computer, Inc. build 1809)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import threading FreeBSD still appears to have various problems with its threading when using Apache. If Python is using threading and Apache isn't, there may be a clash in terms of which threading libraries are used. I know people who simply haven't been able to get threaded Apache to work at all on FreeBSD. You might want to take this whole issue over to the mod_python mailing list as it would appear not to be Django specific, unless you are using PythonImport to import a module which is in turn import Django at Apache startup rather than first request.

Re: truncate string after x characters
thanks. since truncatewords and truncatewords_html are predefined filters, I guess that truncate should also be one (just my opinion). patrick On 20 Aug., 12:33, Malcolm Tredinnick <[EMAIL PROTECTED]> wrote: > On Mon, 2007-08-20 at 11:52 +0200, patrickk wrote: > > how do I truncate a string (in the template) after a certain amount > > of characters? > > I know there´s a truncate-filter, but it works with words and not > > characters. > > There's #5025 in Trac. > > This shouldn't be seen as any endorsement for that ticket, since I'm not > convinced it belongs in core and haven't really worried about making any > kind of decision.

Re: emulating an existing session in tests
I am using the api via shell (i.e.: python manage.py shell) as
follows:
>>> from django.contrib.sessions.middleware import SessionWrapper
>>> from django.test.client import Client
>>> c = Client()
>>> s = SessionWrapper('8a3dd9235b8e718c3f7e890106180528')
>>> c.session = s._session
>>> c.session
{'_auth_user_id': 840, '_auth_user_backend':
'django.contrib.auth.backends.ModelBackend'}
>>> c.get('/messages/')
The last line says the request is not considered as being form an
authenticated user because HttpResponseForbidden is returned when an
anonymous user tries to access /messages/.
I am supplying the data in the session, so I think it must be ok. Am I
thinking wrong?
Thanks,
oMat

truncate string after x characters
how do I truncate a string (in the template) after a certain amount of characters?

Re: Attribute Error
Guys I spent quite a while yesterday reading through the newforms section of the docs, and thought I'd taken everything in. As a python novice, I wrote a test script and couldn't replicate the error, so was beginning to wonder whether I was cracking up! After reading Malcolm's (comprehensive) response, it does make alot more sense and I feel to have a better understanding of how the newforms library hinges together. I've got to say as someone new to django I'm really impressed at the level of support you guys have got going on.
