There's a closing parenthesis as well (after polls.id):

But then, you are putting polls.id in your query, and you are not
selecting from a polls table, so something is not right there. Maybe
you need a JOIN, or is polls.id supposed to be a Python attribute
reference? If so, it can't go directly in SQL.

Preformatted text in templates
Hi,
I am quite new to Django; been working on an app using Django for 3-4
days.
I have a need to show large piece of text as is. I had issues with
linebreaks, which I solved using
{{ text|linebreaks }}
Now, the problem is with whitespaces. I have to display them as is.
One of the solutions is to surround {{text}} with tag.
Is there any other way (a filter or something) that can achieve the
same?
Thanks

I'm looking but I don't see anything you are doing wrong. It's been a

Trying the query in a 0.91/MySQL installation on both Mac OS X and an

Extreme file uploading
I'm working on a little app to manage a podcast RSS feed (believe it
or not, someboody actually edits it by hand now). So my first thought
was to use the FileField for uploading the enclosure. This worked fine
except for one issue: The podcast in question is for video, and the
files are typically 200 MB. I watched top while uploading one of these
and the mini-dev server went up to 1.5 GB resident (good thing I had 2
GB of RAM), but obviously this presents a problem. I don't know if
apache/mod_python would work any better or not. I'm guessing the
django server simply reads the entire request into memory and then
parses, while apache may start writing to a temp file somewhere.
Anyway. To work around this particular problem I changed it to a
FilePathField and stipulated that the files (which were already on the
server) would be uploaded by some other means. There are a couple
problems with this:
1) You lose all the nice get_*_url(), get_*_size() and friends that
FileField gives you.
2) To use an existing directory structure, I had to use the recursive
option, but it seems that the value that is stored loses any
subdirectory name between the path and the actual file. I filed a bug
with a patch for this (magic-removal):
http://code.djangoproject.com/ticket/1536
3) It stores the complete path in the database, and there's no obvious
way to trim the path down so you can paste the subdirectory/filename
onto the end of a URL short of repeating yourself and manually
clipping off the initial path, and there's no way I can see to get
that value out of the model. i.e. If I am using:
enclosure = models.FilePathField(path="/var/media/podcasts",
recursive=True, match="\.mp4$")
and I select the file /var/media/podcasts/banking/commercial.mp4,
there's not a way I can get it to just chop off the original path. I
suppose I could do this:
PODCAST_PATH = '/var/media/podcasts'
...
enclosure = models.FilePathField(path=PODCAST_PATH,
recursive=True, match="\.mp4$")
def get_enclosure_uri(self):
return enclosure[len(PODCAST_PATH):]
and then use {{ MEDIA_URL }}/{{ object.get_enclosure_uri }} in the
template. (or something like that)
Any other suggestions? Maybe a variant of FileField or an additional
option that disables upload in the admin interface but let's you pick
matching files out of MEDIA_ROOT?

numeric formatting
Is there a template filter for turning a large integer into a human readable number? 1234567 --> 1,234,567 12345 --> 12,345 I don't think that python built-in formatting can do this. (Am I wrong?) Assuming there isn't already a simple filter that will do this, what do I need to learn about in order to create my own filter?

It is apparently possible to change this behavior. Hi Sam, You can't change the naming convention on a global level, but you can manually override the name of the database column by specifying "db_column" in the field parameters. For example: foo = meta.ForeignKey(Foo, db_column='foo') The docs are here: http://www.djangoproject.com/documentation/model_api/#general-field-options Adrian -- Adrian Holovaty holovaty.com | djangoproject.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Assigning default value for field in admin
Hi there, i'm currently writing my first Django application. I must say that Django is really what i've been searchin for for years. Right now I have a problem concerning the usage of the admin interface. I have a model like this: from django.core import meta from django.models.auth import users class Series(meta.Model): name = meta.CharField(maxlength=255, primary_key=True) contributor = meta.ForeignKey(users.User) #... When editing or creating a new object of class Series i would like Django to automatically insert the current logged in user as the "contributor". I dont see any way to do this inside the class definition. Hope you guys can help me here.

On a mod-python list I saw a suggestion I reproduced it in python interpreter. I don't think it is mod_python-related problem. There are two problems as far as I can tell: 1) QueryDict uses the hacks with class-level variables, which are reassigned temporarily during copy(). Its base class (MultiValueDict) does the same. It's a no-no for multithreaded programming. The same goes for module-level variables. In short: all changes to common variables should be analyzed and synchronized, or avoided. The latter is the best approach. 2) copy.deepcopy() doesn't like to be fooled with dynamic class modifications, e.g. with replacing __setitem__. Example: = class Ex(dict): def __init__(self, mutable=True): dict.__init__(self) self._mutable = mutable def _setitem_if_mutable(self, key, value): print 'Setting', key, 'to', value self._assert_mutable() dict.__setitem__(self, key, value) __setitem__ = _setitem_if_mutable def _assert_mutable(self): if not self._mutable: raise AttributeError, "This Ex instance is immutable" def copy(self): "Returns a mutable copy of this object." import copy # Our custom __setitem__ must be disabled for copying machinery. old_mutable = self._mutable self._mutable = True cp = copy.deepcopy(self) self._mutable = old_mutable return cp a = Ex() # it works fine # a is fully functional b = a.copy() # it works fine # b is fully functional c = b.copy() # it blows: AttributeError: 'Ex' object has no attribute '_mutable' c = a.copy() # it works fine = Try to play with it. The right way to handle copy/deepcopy is to define proper ___copy__/__deepcopy__ methods, or to define custom pickling helpers. Incidentally it was a point of the hacks in #1. I implemented a patch for #1 and #2, and sent it to Alex. If he confirms it, I'll create a ticket. Otherwise I'll dig more. I am afraid we'll find more places with class-level (like this) or module-level (like in uncommitted #1442 patch) variables.

trying to get my first app up.
i am having a rough time getting my first app running..
i made a new project called "learningOpps"
the admin works fine..
i set up a new application called "opps"..
everything seems to have built just fine..
the problem is..
now, i added this to my urls:
(r'^site_media/(?P.*)$', 'django.views.static.serve',
{'document_root': '/path/to/LearningOppsDjango/learningOpps/media'}),
so i can serve the images on my development server..
(r'^opps/$','learningOpps.opps.views.index')
to handle http://127.0.0.1:8080/opps
i added this to my views in opps(opps/views):
from django.models.opps import opps
from django.utils.httpwrappers import HttpResponse
from django.core.template import Context, loader
from django.core.extensions import render_to_response
def index(request):
return render_to_response()
but no matter what happens, i get this:
ViewDoesNotExist at /opps/
Could not import learningOpps.opps.views. Error was: cannot import name
opps

Dropping down to the raw SQL level is easy...

How to use form fields
I use a custom manipulator that creates field_names.These filed names
can be a different. To create fields I use
formfields.IntegerField(field_name="Pieces_"+`v`, maxlength=4)
where Dynamic_value changes.
Normaly, for static field, I can use in a form {{form.FieldName}}.
If fileds are generated in a dynamic way, how can I use it in a form?
For example my custom manipulator can create
{{form.ID_1}} only but also
{{form.ID_2}},{{form.ID_3}} ... etc.
So, is there a list where all fields are?
Thanks.

RSS Feeds - what am I doing wrong?
Hi.
I'm trying to put together a feed for a specific blog in my system.
I've been following the example at
http://www.djangoproject.com/documentation/syndication/#a-complex-example
Unfortunately, when I access the feed, I get:
- - - - - - - - - - - - - - - - - - - - - - - -
TypeError at /rss/blog/1/
items() takes exactly 2 arguments (1 given)
Request Method:
GET
Request URL:
http://localhost:8000/rss/blog/1/
Exception Type:
TypeError
Exception Value:
items() takes exactly 2 arguments (1 given)
Exception Location:
/usr/lib/python2.4/site-packages/Django-0.91-py2.4.egg/django/contrib/syndication/feeds.py
in __get_dynamic_attr, line 38
- - - - - - - - - - - - - - - - - - - - - - - -
Here's the feed implementation:
- - - - - - - - - - - - - - - - - - - - - - - -
# Die neuesten Einträge in einem bestimmten Blog
class BlogFeed(Feed):
def get_object(self, bits):
if len(bits) != 1:
raise ObjectDoesNotExist
return blogs.get_object(id__exact=bits[0])
def title(self, obj):
return "www.trogger.de - Neue Beiträge in %s" % obj.title
def link(self, obj):
return "/world/blog/%s" % obj.id
def description(self, obj):
return "Neue Einträge in %s -- Blog von %s" % ( obj.title,
obj.get_author().get_full_name)
def items(self, obj):
return submissions.get_list(blog__id__exact = obj.id,
order_by=('-date_submitted',), limit=5)
- - - - - - - - - - - - - - - - - - - - - - - -
According to the docs, the RSS framework should be calling my
"items(self, obj):" method. Unfortunately, it seems to be only looking
for "items(self)", which isn't there.
My feeds definition is:
feeds = {
'travelreports': LatestTravelReports,
'newblogs': NewBlogs,
'blog': BlogFeed,
'blogentries': LatestBlogEntries,
}
so for /rss/blog/1/ it should be calling my BlogFeed implementation.
The "simple" feeds (with no parameters) work fine, by the way.
Django release is "Django-0.91-py2.4.egg"
Can someone please point out my mistake? I'm sure it's a case of not
seeing the forest for the trees.
Thanks,
Daniel

Need help for query, how could i do this with django ? or a raw SQL.
Hello,
I was trying to play with custom query but i didnt manage to get it
working,
for example this one whcih i found on the mail list :
Polls.get_list(
select={
'choice_count': {
db_table='choices',
db_columns=['COUNT(*)']
kwargs={
where=['poll_id=polls.id']
}
}
}
)
the 'choice_count' its like a select stuff AS choice_count ? what is it
used for.
Then related to my model :
i want the name of the top 5 users who wrote the most recipes.
Here is my model
RECIPE
- name
- stuf ect [...]
- owner USER FK
USER (from django)
- name
in sql i would do
SELECT auth_users.username, COUNT(*) AS count FROM auth_users,
recettes_recipes WHERE auth_users.id=recettes_recipes.owner_id GROUP
BY username ORDER BY count DESC;
My eternal respect to the solver.

MR Branch - list_filter with ForeignKey -- Help
Hi
I am trying to get the list_filter to work with a ForeignKey field in
the admin site.
It works fine with with a standard charfield with choices, but when I
move those values out into a seperate model and add the filter fields
in to the list I dont get filters on the right hand side. I searched
the forum, and cant see anything relevant. I also looked at the code
and it should work in thoery.
Any ideas ?
My model looks like this:
class Site(models.Model):
name = models.CharField(maxlength=50)
description = models.TextField(maxlength=200)
class Admin:
list_display = ('name', 'description')
search_fields = ['name', 'description']
def __repr__(self):
return "%s - %s" % (self.name, self.description)
class Department(models.Model):
name = models.CharField(maxlength=50)
description = models.TextField(maxlength=200)
class Admin:
list_display = ('name', 'description')
search_fields = ['name', 'description']
def __repr__(self):
return "%s - %s" % (self.name, self.description)
class TelDirEntry(models.Model):
first_names = models.CharField(maxlength=150)
last_name = models.CharField(maxlength=50)
site = models.ForeignKey(Site, verbose_name='Office Location')
department = models.ForeignKey(Department,
verbose_name='Department')
office_tel = models.CharField(maxlength=50)
mobile_tel = models.CharField(maxlength=50, blank=True)
home_tel = models.CharField(maxlength=50, blank=True)
class Admin:
list_display = ('first_names', 'last_name', 'site',
'department', 'office_tel')
list_filter = ['last_name', 'department', 'site']
#search_fields = ['first_names', 'last_name', 'site',
'department', 'office_tel']
class Meta:
verbose_name = 'Telephone Directory'

A newbie question about log files
Hi I am hosting my Django webapp on DreamHost. No real problems so far. And let me just say: I really like the work you've done with Django. Simple and cohesive. Anyway, back to my problem. As I said, everything works fine, but I am chasing this bug I only seem to have when I deploy. I do an AJAX call, and in some cases, I get back an HTTP 500. Ok, fine, Iithought, let me have a look at log files and see what the exact problem was... oops, but I can not find the log files. Been poking around for a while without success, so I was wondering if you could give me a helping hand. Apache error logs show nothing, and I was hoping to see at least as much output as generated by the test server (manage.py runserver). I'll appreciate you help.
