Dynamically add a line to an inlineformset

[Andew Gee]

Does anyone know how to add a new line to anlineformset dynamically? I
have a page that contains an inlineformset and I need to be able to
click a button and add a new line which will then be saved when the
form is submitted, is that possible?

Thanks
Andrew

Thanks for the confirmation.  In that case I'll have to write my own
render_to_response() wrapper.

Models.py and overriding the get_or_create class method. Help please with obj = self.model(**params)

[rh0dium]

Hi all,

I have a class in which I want to override the get_or_create method.
Basically if my class doesn't store the answer I want it do some
process to get the answer and it's not provided. The method is really
a get_or_retrieve method.  I have heavily borrowed this from db/models/
query.py and I can't figure out the line "obj = self.model(**params)".
I don't understand what the attr model needs to be and it's not
intuitively obvious what this should be. Even looking back at the
query.py I can't figure this out. Can someone explain this to me? I
would really like to understand it and fix my code.

So here's the class:

class P4User(models.Model):
  user  = models.CharField(max_length=100, primary_key=True)
  fullname  = models.CharField(max_length=256)
  email = models.EmailField()
  access= models.DateField(auto_now_add=True)
  update= models.DateField(auto_now_add=True)

  @classmethod
  def get_or_retrieve(self, username, auto_now_add=False):
try:
return self.get(user=username), False
except self.model.DoesNotExist:
import P4
import datetime
from django.db import connection, transaction, IntegrityError
p4 = P4.P4().connect()
kwargs = p4.run(("user", "-o", username))[0]
p4.disconnect()
params = dict( [(k.lower(),v) for k, v in kwargs.items
()])
obj = self.model(**params)
sid = transaction.savepoint()
obj.save(force_insert=True)
transaction.savepoint_commit(sid)
return obj, True
except IntegrityError, e:
transaction.savepoint_rollback(sid)
try:
return self.get(**kwargs), False
except self.model.DoesNotExist:
raise e

  def __unicode__(self):
return str(self.user)

I am able to get the params but I haven't defined self.model. I don't
understand what that needs to be and it's not intuitively obvious what
value that should be. Even looking back at the query.py I can't figure
this out. Can someone explain this to me? I would really like to
understand it and fix my code.

Thanks

hi friends,

once again i need your help. I want to implement a simple friendship
invitation/rejection mechanism. In more words, a user sends an

or reject it...


What parts of django should i look into? (i am new to django!) .

In the morning i will look into
http://code.google.com/p/django-friends/ source code. any other
sources i should look?

ideas or anything is welcome!

If your copy of django/utils/__init__.py contains that text than whatever
tool you are using to unpack the tar.gz file is broken.  There have been
reports of this before and as I recall the problem was the tool (I don't
recall what it was) could not handle unzipping 0-byte files.  Try using a
different uncompress/unzip tool.

Post your Apache configuration snippet for how you have set up
mod_wsgi. Sounds like you are using mod_wsgi daemon mode, but
confirmation would be nice, along with the options you are using for
WSGIDaemonProcess. Also indicate whether your Apache is running PHP
using mod_php and what MPM Apache is built for, prefork or worker.

Template Filters

[WilsonOfCanada]

Hellos,

I was wondering if there is a filter that can remove these '\' that
python added when strings are appended to a list or dictionary.  I
cannot use cut because I still need one of the '\'

ex.  C:\\moo

Code:

arrPlaces = []
intPoint =0

while (len(testline)):
testline = fileName.readline()
print testline
arrPlaces[intPoint].append(testline)
intPoint += 1

d["places"] = arrPlaces
return render_to_response('rentSearch.html', d)

> C:\moo
> C:\supermoo

the HTML using Django has:

{{ places|safe }} but returns ['C:\\moo', 'C:\\supermoo'].  I was
wondering of there is a filter for the template that would return ['C:
\moo', 'C:\supermoo'] instead.

Thanks

Post the full traceback, not just the error message, so that people who

Re: Displaying username on every page

[grahamu]

If you use RequestContext(), you automatically get visibility to the
current user and their permissions. See
http://docs.djangoproject.com/en/dev/topics/auth/#authentication-data-in-templates.
My base templates use a block like this:

{% block user %}
{% if user.is_authenticated %}
User: {{ user.get_full_name }}{% if user.is_staff %}
[staff]{% endif %}
Log out
{% else %}
Log in or Sign up
{% endif %}
{% endblock user %}

use RequestContext - do not forget to add this in settings.py:

TEMPLATE_CONTEXT_PROCESSORS = (
'django.core.context_processors.request',

You can then get the user as request.user in the template

Displaying username on every page

[John Barham]

Apologies in advance if this is a FAQ but I've searched the list and
can't find a precise answer.

I want to display the login status of the user at the top of every
page.  If they were logged in, it should say something like "Logged is
as  (Log Out)" and if they're not logged in it should show a
link to the login page.

I could of course pass in the username as a dictionary value for each
page, but this quickly becomes tedious.  I also use render_to_response
a lot and if I understand correctly it doesn't pass through the user
info automatically, but will if you set the context_instance parameter
to a RequestInstance.  Is there a way I can access the user info from
any page without having to do the above?

Adding ManyToMany field to django comments

[grahamu]

In general, I'm wondering how to retrieve a Queryset provided to a
Form (choices for a ManyToMany field) from within a view that only
accepts POST data from that form. This isn't really a question about
extending django.contrib.comments, but that framework provides a good
point of reference for the issue.

For example, suppose I wanted to add: "reviewers = models.ManyToMany
(User)" to the django.contrib.comment Comment model. This would be a
list of Users who are allowed to review the comment, specified by the
comment creator.

In order for this to work we need to provide a Queryset of Users when
creating the form. This can be accomplished with a template tag of the
form "{% get_comment_form for [object] with [reviewers] as [varname]
%}", where 'reviewers' is a Queryset passed in the template context.
This works fine.

However, when the form is posted, we don't have visibility (in the
post view) to the Queryset of possible reviewers. The post view, after
checking the validity of several other pieces of data, creates a new
comment form to check the validity of the received data. Of course the
form must have a Queryset for the 'reviewers' field, and this isn't
part of the request POST data.

Any ideas how one might either pass the queryset data to the view in
the form, or some other way to manage the form validation in this
situation?

Re: How do you remove a manytomany relationship in django?

[Ray]

Hi,
thanks for the fast response! I'm trying to use the remove function
right now just like this sample code:

# And from the other end
>>> p2.article_set.remove(a5)
>>> p2.article_set.all()
[]
>>> a5.publications.all()
[]

from http://www.djangoproject.com/documentation/models/many_to_many/

I'm doing "Group.objects.get(id=3).members.remove(member1)"

and getting this error: 'ManyRelatedManager' object has no attribute
'remove'

I also did help to find out what methods ManyRelatedManager had, and
indeed it didn't have a 'remove' method, only: clear, create,
get_or_create, and get_query_set

AND THEN,

I tried the remove function with the queryset object,
"Group.objects.get(id=3).members.all().remove(member1)"

and I got this error: 'QuerySet' object has no attribute 'remove'

I'm at a loss as to how I'm supposed to update these relationships

Well, that is weird. MayRelatedManager definitely *does* have an
attribute 'remove'. With these basic models:

class Category(models.Model):
title = models.CharField(_('title'), max_length=100)

class Post(models.Model):
title = models.CharField(_('title'), max_length=200)
categories = models.ManyToManyField(Category)


the following works fine:
>>> from blog.models import Post, Category
>>> p=Post.objects.create(title='dan')
>>> c=Category.objects.create(title='category')
>>> p.categories.all()
[]
>>> p.categories.add(c)
>>> p.categories.all()
[]
>>> p.categories.remove(c)
>>> p.categories.all()
[]

So it works for me, I can't imagine what is happening with your setup.

Re: PIL & imagefield validation

[zayatzz]

OK. Apparently this is not PIL problem.

I replaced validation errormessage with custom messages for debugging
and i found out that imagefield validation fails here :

try:
# load() is the only method that can spot a truncated
JPEG,
#  but it cannot be called sanely after verify()
trial_image = Image.open(file)
-->   trial_image.load()

If i comment that .load() line out i got IOerror:
IOError at /profile/edit/

decoder jpeg not available

So apparently, even though i reinstalled jpeg before installing PIL,
there is something wrong with jpeg module pathing and i have to remove
and reinstall that too.

Re: PIL & imagefield validation

[zayatzz]

I followed the instructions on that website.

I used kfind to find all files/folders containing PIL. I removed
PIL.pth files and PIL folders from several places. Then i tried
importing PIL in python prompt and got the error. - no pil in the
system.

Then i reinstalled PIL. tested it and got the validation error message
again. Then i deleted django, i deleted it under python2.6 site-
packages, and dist packages, i deleted the unpacked folder also.
decompressed the tar file, built and reinstalled it again. Still no
changes.  So i  guess only thing to try is either troubleshoot the
fields.py and find out why it gives the error and if it can or cannot
import the pil, or reinstall ubuntu and start from clean system.

Or do you have any other ideas?

Alan.

Function fields in admin change view?

[deadguy]

Hello,

Can you add fields whose values are generated by functions to the
admin change view like you can to the list view?  They would have to
be read only, of course, since there's no db column for them.  I'd
like them to be presented in the fieldset along with everything else.

thanks!

Google app engine patch translation : model_set.all doesnt work

[justin jools]

It seems google app engine patch doesnt support _set.all.  I have
tried my original django only version and it works but with google app
engine patch does not.

my template code:

 {% for model in object.product_model_set.all %}
{{ model.full_title }}
 {% endfor %}

I dont how / what to replace _set.all with, if I set it to model.all
it still does nothing.
Thanks...

here is my model:


class Product_Model(db.Model):
"""  Model Details """
type  = db.ReferenceProperty(Product_Make, required=True,
collection_name='make_set')
title = db.StringProperty(required=True)
slug  = db.StringProperty(required=True)
derivative= db.StringProperty(required=True)
released  = db.DateProperty(auto_now_add = 1)
picture   = db.BlobProperty(default=None)
review= db.TextProperty(required=True)
genre  = db.ReferenceProperty(Product_Type, required=True,
collection_name='genre_set')

def __unicode__(self):
return '%s' % (self.title)

class Meta:
ordering = ('title',)

@property
def full_title(self):
return '%s %s' % (self.title, self.type)


@permalink
def get_absolute_url(self):
return ('model_detail_url', None, { 'slug': self.slug })

custom authentication backend not being used...

[Jay]

First off, I'm using Django 1.1.

I've been having problems getting my custom authentication backend to
work, specifically in the "admin" site.

I've been using this page as guide to put together an auth backend
that uses my subclass of the User model to authenticate.

http://scottbarnham.com/blog/2008/08/21/extending-the-django-user-model-with-inheritance/

I will post all code below, but for the moment here is the problem.
I'm trying to log into the django admin site and I'm getting an
exception on "check_password()" that shows me that the admin login
system is using the User.check_password() rather than my subclass'
check_password(). I'm working with an existing database here and I
don't want to change my password hashing scheme if I don't have to.
The thing that's driving me crazy is that the admin site doesn't seem
to be using my User subclass.

Is there something I'm forgetting/missing here?

Thanks for any help anyone has to offer.

Here is all relevant code (if there is something I'm forgetting, do
let me know):

Hi Thomas,

Thanks for the reply.

I have postgres max_connections=100, but when I run "select count(*)

Re: Error in setting up psycopg2

[Simon Lee]

Hi Thomas,

Tried your method and modified /mysite3/apache/myapp.wsgi as followed:

import os, sys
sys.path.append('/Users/myname')
sys.path.append('/Library/Frameworks/Python.framework/Versions/2.6/lib/
python2.6/site-packages/django')
sys.path.append('/Library/Frameworks/Python.framework/Versions/2.6/lib/
python2.6/site-packages/psycopg2')

try:
import psycopg2 as Database
except ImportError, exc:
import sys
raise ImportError('%s %s' % (exc, sys.path))

os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite3.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()



Now the error log is as followed:

Re: Database design question

[ringemup]

Validation turns out to be well-nigh impossible using parent / child
aliases, but pretty easy with parent / child accounts.  Here's what
I've ended up with:

class Account(models.Model):
user = models.ForeignKey(User, unique=True, null=True, blank=True)
alias = models.CharField(max_length=32, unique=True)
parent_account = models.ForeignKey('self', related_name='children',
null=True, blank=True)

def __unicode__(self):
return '%s owned by %s' % (self.alias, self.get_owner())

def save(self, force_insert=False, force_update=False):
if not Account.is_valid_parent_or_child(self.user,
self.parent_account):
raise AccountInheritanceError
super(Account, self).save(force_insert, force_update)

def get_canonical_alias(self):
if self.is_child():
return self.parent_account.get_canonical_alias()
return self.alias

def get_owner(self):
if self.is_child():
return self.parent_account.get_owner()
return self.user

@staticmethod
def is_valid_parent_or_child(user, parent_account):
# We need either a user (meaning this is a primary account)
# or a parent (meaning this is a child account), but not both
if bool(user) == bool(parent_account):
return False
if parent_account.is_child():
return False
return True

def is_parent(self):
return bool(self.user)

def is_child(self):
return bool(self.parent_account)

I'll probably end up shunting any required account fields into a
Profile model and either a)attaching that to Account with a nullable
one-to-one relationship, and making that required for parent accounts;
or b) making the Profile model the AUTH_PROFILE_MODULE rather than
Account (which is currently).

Re: Problem with "Cancel" button

Thanks Thomas for your reply. I just tested it with Firefox. "Cancel"

With IE "Cancel" button has such a problem.

This has nothing to do with doctests. The __unicode__ function for
your GeneralProperties model is:

def __unicode__(self):
return "General Properties of", self.boat

As the error says, this is returning a tuple, not a unicode string.
You need to format this as you have done with all the other models.

By the way, none of your unicode methods are actually returning
unicode values, they are returning bytestrings. This *will* cause
failure as soon as you have a name that isn't ASCII - eg an accent.
You need to make sure that any literal string is prefixed by u to make
it work:
return u"General Properties of %s" % self.boat

Re: is Django a good choice for a LAN app?

[snfctech]

UPDATE

Looks like the Django multi-DB support didn't quite make it in yet:

http://groups.google.com/group/django-developers/browse_thread/thread/267a2fd7104f0209?hl=en

On another note, I came across the web2py project, which has multi-db
support built in - "table attributes are attributes of a database
connection."  That's what I'm talkin about!

I think the answer to this thread may be:

"Yes, Django is a good choice for a LAN app, but depending on your
specific needs (e.g. multi-db support), another framework may be
better."

I also found out that Django + Elixir may be an option for multi-db
support, so I may evaluate this as well if web2py falls short.

Re: Database design question

[ringemup]

I'm not asking as a Django / foreign key thing.  I'm having a lot of
trouble referencing each model from the other's save method for
validation purposes, because there's always going to be one that's
declared after the other.

Figured it out.  Apparently when I did my intial test I did not have a

That model works on doctests but...

[Mirat Bayrak]

http://dpaste.com/82737/ < here is models.py , as you see i wrote
doctests for every model and they are working well. But when i try to
create GeneralProperties or AccomodationProperties from admin page,

user profile problems

[Justin]

I am sure this is a newbie mistake but I can't seem to find exactly
the right setting.  I have create a user profile class.  I am trying
to attach into my django project via the AUTH_PROFILE_MODULE setting
in the settings.py file.

The error I get is as follows when I try to retrieve the profile
>>> from django.contrib.auth.models import User
>>> from engine.models import *
>>> user = User.objects.get(pk=1)
>>> prof = user.get_profile()
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python2.6/dist-packages/django/contrib/auth/
models.py", line 285, in get_profile
self._profile_cache = model._default_manager.get
(user__id__exact=self.id)
AttributeError: 'NoneType' object has no attribute '_default_manager'

My AUTH_PROFILE_MODULE = 'engine.UserProfile'

Rough project layout

/logi - site folder
/logi/engine/models model folder
/logi/engine/views views folder

The userprofile exists within the /logi/engine/models folder in a file
call models_file.py.  so the full path to my user profile class is /
logi/engine/models/models_file.py

I have tried several variations of the AUTH_PROFILE_MODULE string but
none seems to work.
 engine.UserProfile
 models.UserProfile
 logi.UserProfile

User Class as defined
class UserProfile(models.Model):

panel_id = models.IntegerField()
email = models.EmailField()
status = models.CharField(max_length=1)
user = models.ForeignKey(User, unique=True)

def __unicode__(self):
return "%s - %s" % (self.panel_id, self.email)

class Meta:
app_label = 'engine'

Any help would be appreciated,
  I am sure this is something simple.

Thanks,
  Justin

Re: Django "freezing" after a few minutes?

[Thomas Guettler]

Just a first guess:

How many wsgi-clients access the db server at the same time?
Maybe the db does accept only N, while apache/wsgi tries it
with N+1. Then the connection could hang.

What do the wsgi processes do? You can use "strace -p WSGI-PID" to find
this out.

You can sent SIGINT (like ctrl-c) the the PID. In the stacktrace
you can see where the python code was hanging (should be in apache
error log).

Django "freezing" after a few minutes?

[erikcw]

Hi,

I'm running Django through mod_wsgi and Apache (2.2.8) on Ubuntu 8.04.

I've been running Django on this setup for about 6 months without any
problems. Yesterday, I moved my database (postgres 8.3) to its own
server, and my Django site started refusing to load (the browser
spinner would just keep spinning).

Pages will load when I first start apache, but after about 10 mintues,
it just stops. Apache is still able to serve static files. Just
nothing through Django.

I've checked the apache error logs, and I don't see any entries that
could be related. I'm not sure if this is a WSGI, Django, Apache, or
Postgres issue?

Any ideas?

Thanks for your help!
Erik

Re: Problem with Django/Jython and Postgres backend

Hi Brandon,

I don't use Jython and not OSX, but if you look at the stacktrace

"1 given" is the implicit "self". This means your DatabaseClient wants
one argument, but in base.py none is given. Try to find the souce
of DatabaseClient.__init__(self, ...)

Running test suite without CREATE permission.

[J. Cliff Dyer]

When running a test suite, django starts by creating a test database.  I
am trying to run it on a webfaction account, and I can create an extra
database through the site's control panel, but I can't give django
permission to create one.  Is there a way to get django to use a
pre-existing database for unittests?

Cheers,
Cliff

When does it work and when not? Does it work in one browser always, and
in a different browser never? Django does not do any random stuff.
What happens if the redirect does not work?

I stopped getting any values from request.POST or request.GET. I use

I guess the error is in cancel.html. You need to post it here.

Re: Error in setting up psycopg2

[Thomas Guettler]

Hi,

you need to know what sys.path looks like. This is a list of
searched directories.

try:
import  # Import lines that failes
except ImportError, exc:
import sys
raise ImportError('%s %s' % (exc, sys.path))

Then check if the stuff you want to import is on sys.path.

You can, it just creates headaches. At least one of the ForeignKeys needs to

Re: Adding model-specific exceptions like DoesNotExist?

In that case you can create an abstract model class and use that instead of

class Meta:

class DoesNotExist(Exception):
pass

Re: Adding model-specific exceptions like DoesNotExist?

Yes, and then I also need to import that class into every place that I

The benefit of making it part of the model is that any place I'm using
it, I already have the exception handy:

try:
# ... do some things
m = MyModel(foo=bar, baz=bling)
m.save()
except MyModel.FrobNotAllowed:
# handle the exception...

It's not a big deal but I figured that emulating the framework isn't a

Subselect in query set .extra(tables=...)

[Matt Hoskins]

A couple of times I've wanted to be able to pass in a sub query as a
table in query_set.extra to be able join in some extra information but
have been thwarted as the query code always insists on quoting what
you pass in as tables to .extra (i.e. it assumes it's always table
names).

Back in 2005 with issue #967 someone put in some code to allow this,
but as part of qs-rf this was dropped (although the way it was decided
whether to quote something back then looks a bit clunky).

With postgres at least, if you pass in a subselect to the FROM it has
to have an alias, so if the tables argument to extra were to support
subselects it would need to allow something like "(SELECT foo FROM
blah) AS alias_of_subsel" being passed in.

I can't see how to pass in a subselect via .extra with Django 1.1 - if
anyone knows how to that would be useful. It seems unnecessarily
limiting for .extra not to allow subselects to be passed in where the
database engine supports it. A simple fix (although I don't know if it
has any bad consequences I can't think of) at least for postgres would
be if the backend's quote_name function didn't quote what's passed in
if it begins with "(" as subselects in the from in postgres always
have to be in parenthesis. I'm going to monkey patch
connection.opts.quote_name in my code for now to behave that way.

All you really need is:

class DoesNotExist(Exception):
pass

I generally create a Utils app in my project with a modelUtils.py where I
put things like that. Then you can just import the exception and use it in
any of your models.py files.

Adding model-specific exceptions like DoesNotExist?

[Idan Gazit]

Hey all,

I'd like to add some custom exception to a model of mine,
Foo.FrobNotAllowed, along the lines of ModelName.DoesNotExist.

>From looking at models/base.py, it looks like the pattern is to
override __new__() and use add_to_class. Something like:

def __new__(cls, name, bases, attrs):
new_class = super(MyModel, cls).__new__(cls, name, bases, attrs)
abstract = getattr(attr_meta, 'abstract', False)
if not abstract:
new_class.add_to_class('FrobNotAllowed', MyExceptionClass)
return new_class

Is this the pattern I should be emulating for the kind of thing I'm
seeking?

IE requires your domain to have at least 2 parts - so you cannot set,
for example, cookie.domain like .application even such a domain is
valid in your network.

I have a similar problem with FF and Etch (with Django 1.0 and 1.1

Works when running on my notebook (Ubuntu 9.10a4 with Django 1.1).

What I would recommend is to drop the ForeignKey in the Account table. You
can always retrieve the set of Aliases for an Account based on the
ForeignKey from Alias to Account. I believe that you will even be able to
access Account.alias_set in your code, though if not you can always get
Alias.objects.filter(Account_id=xx) and for the primary you will be able to
say either Account.alias_set.filter(parent__isnull=True)or
Alias.objects.filter(Account_id=xx).filter(parent__isnull=True)

Are you sure you have set up data in database correctly? Your model
allow null value in photo_set, so maybe everything is working well and
you forgot to fill database... ;)

You will need to provide more information, such as the actual
traceback. I don't believe that the 'print item.photo_set' line can be
working if in the very next line you're getting an error which in
effect says that item.photo_set is None.

As an aside, I must say that you are very likely to get extremely
confused with your models and fields named the way they are. 'xxx_set'
is usually used in Django for the automatically-created reverse
relation on ForeignKeys - so in this case, the reverse relation from
PhotoSet to Event would be called event_set - and this is always a
queryset. Calling your actual FK 'photo_set' is bound to lead to
confusion.

As has been explained, you can't do this straight out of the box.
However it is trivially easy to write a custom template filter that
will do it.

@register.filter
def get(dictionary, key):
return dictionary.get(key)

Now you can do {{ dictionary.get:5 }}

You don't understand me.
WQhat I want to achieve is to use student.id as a key in dictionary
(Im talking abous template)
If I use:

{% for student in students %}

... do sth ...

 {{dictionary.student.id }} 

{% endfor %}

using dictionary.1 works using dictionary.student.id doesnt work
because there is no such key like student in dictionary. What can I do
to convert student.id to value and pass it like for example dictionary.
(student.id)

if in this iteration student.id = 5 then i want to have {{ dictionary.
5 }}

Re: OK to put app_directories before filesystem template loader?

[David Christiansen]

Well, it doesn't seem to make much sense to me.  I use the default
order so that I can place files in a site-level templates directory in
order to override the default templates in the app directory without
having to directly open it up and modify its template files.

Re: Flatpages - what am I missing to make these work (advice, please)?

[gegard]

Thank you! That has resolved my problem.

The admin shell does not show the site id number by default, so I
supposed that removing the default 'example.com' and adding 'mysite'
would enable Django to reuse id 1. I should have assumed otherwise -
the new site was id == 2, of course. I should have edited
'example.com' rather than removing it.

Re: Using custom table instead of "user" in django

[Marek Wawrzyczek]

How about writting adapter to the django user class? It can have
descriptor for login (getting login would return users email). While
creating such user login would be set (only once, during creation) for
example the following value: user id converted to string preceded by
one character. For other custom fields there can be also descriptors,
but they would reffer to yours customer model (for example adapters
field homepage which would be descriptor would reffer to
customer.homepage).

Django model attribs and property()

[Tracy Reed]

I have been looking into Django since February and not done much with
it in recent months. But the past few days for some reason everything
just clicked and I have cranked out a ton of cool functionality rather
painlessly. I'm loving Django so far! I have just completed my first
real world django project. Thanks Django team!

My project has room for improvement: I just have realized that one of
the attributes on one of my models depends on other outside factors
for its value such that it becomes outdated after being set. I have
very nearly a million instances of this object in the database. So I
can't just update all million of them when something changes.

It should be possible to somehow wrap accesses to this attribute,
recalculate, and return the correct updated value. But I understand
that property() won't work with model attributes and even if they did
I would have to rename the attribute in the model which would not make
the ORM happy.

Also, I notice that the only place I really access this attribute is:

queryset.filter(Status='Good', received__range=(hourago, now)).order_by('Score')

Plus, I'm not sure how the ORM and Python count this as an access to
"Score" (the value I want to recalc/update on the fly) due to the way
it is apparently passed to the ORM as a string.

Suggestions? Thanks!

And what's unexpected about that exactly?

Re: Problem installing Django 1.1 on XP

[Nikola Smiljanić]

Django-1.1.tar.gz
MD5: b2d75b4457a39c405fa2b36bf826bf6b

Same thing. File __init__ in django/utils starts exactly like
traceback says:

Django-1.1/Django was originally created in late 2003 at World Online,
the Web division
of the Lawrence Journal-World newspaper in Lawrence, Kansas.

Re: Using custom table instead of "user" in django

[marekw2143]

How about writting adapter to the django user class? It can have
descriptor for login (getting login would return users email). While
creating such user login would be set (only once, during creation) for
example the following value: user id converted to string preceded by
one character. For other custom fields there can be also descriptors,
but they would reffer to yours customer model (for example adapters
field homepage which would be descriptor would reffer to
customer.homepage).

Regards,
Marek
