If you don't want your group to be absolutely overrun with spam, you pretty
much have to restrict posting to members only.

Even that doesn't deter some spammers, particularly for a group with nearly
10,000 members and high activity.  So, django-users recently started manual
moderation of messages from new members ("new" is defined as anyone who has
joined after this switch was flipped).  Since it was turned on three weeks
ago, it has prevented an average of 4 to 5 spam posts per day from getting
through to the group.

This post was not by a new member, so it wasn't moderated.  I can't read
Arabic so while I may suspect it is spam, I can't say that for sure.  There
are a couple of things about it that argue against it being spam -- it
doesn't contain a gazillion links and it is not an identical copy of a
message the user posted to a bunch of groups.  Looking at the user's profile
doesn't show a pattern of mass posting; the account has been active for six
months without posting much of anything anywhere.  For all I know it's a
legitimate query -- we have had people post in French or Spanish or Italian
and get some help and direction to other-language Django groups.

So, yes, there are some spam-prevention measures taken in an attempt to keep
spam off this list, but they are not perfect.  The moderators are human and
it's probably just a matter of time before someone chooses "post" when they
mean "remove" and some spam will be posted.  I think the reverse has
happened at least once, which is also inconvenient.  Such is life, in the
grand scheme of things ignoring some spam or re-posting a mistakenly
discarded post is not that big a deal.

Client testing with custom http request referrer

[Rob P]

I am writing an application that tracks URLs and stores different
information about them (ie URL, referrer, user agent, etc...).

Currently I am writing unit tests for it and I need to be able to
spoof the referrer to test functionality (I only want to log specific
referrers).
Is there anyway I can set the referrer to lets say "google.com"?

I am using the Django test client: from django.test.client import
Client
I need to access the correct test view which is why I'm not using any
urllib libraries.

If anyone know how to do this and could impart your great knowledge it
would be much appreciated.

Thanks!

I was moderated (because my first posting), and even worse, couldn't
post through Gmane without being on the list, which was *very*
awkward, and then they have spam here nevertheless?

You can put whatever you want into your own custom tags, but this won't
work for normal Django tags. The {{...}} is only used to display the
contents of a variable in a template.

This is the way variables are passed to tags.

Tag arguments rendering

[Yosifov Pavel]

I made own tags. Sometimes I want to "rendering" arguments (when
arguments of the tag are Django-template-expressions). So, I use
template.render() method. All is OK but it's look like this:

{% some_tag {{var}} %}

but in built-in tags this is usually without {{..}}:
{% builtin_tag var %}

What is right style? If I render arguments in another way, I thing it
will be less flexible: it will be impossible to create complex django-
template-expressions...

What is the best practice?

In SQL, all NULLs are unique (NULL != NULL). So this isn't
counter-intuitive at the SQL level and unique_together is enforced at
that level.

I guess the solution is not to allow NULLs in those fields if you can
avoid it, or manually add a more complex check constraint to the
database table (exact syntax and format will depend upon your database).

unique_together and null=True fields

[Wanrong Lin]

Hi,

This topic has been discussed before here:
http://groups.google.com/group/django-users/browse_thread/thread/fcd04f766b101a95/b65b70aa6b03729e?lnk=gst=unique_together%2C+null#

Don't you agree that two field combinations like ("A", null) and ("A", 
null) should be considered identical and hence should be blocked from 
being entered into the database when "unique_together" condition is 
imposed on that field combination? Right now Django does not think so 
and will let both of those two records get into the database, which is 
really puzzling to me. Any rationale for such a counter-intuitive (to 
me) behavior?

Thank you for shedding your light on it.

And if you end up using a template to generate the subject of the
email as well (not an uncommon thing), remember that you **must**
condense the subject to a single line of text.

with the latest python and latest postgres why are you using an

Got it. I had to delete the tabs and use spaces. I guess I won't cut/
paste or use tabs.

Thanks,

I don't know what to tell you.  Cut/pasting your models, fixing the
indentation, and cut/paste your shell queries works properly on my machine.
Are you sure you have not mixed tabs and spaces and so have something that
looks in your editor like it is indented properly when in fact the
was_published_today() definition is indented too far as far as Python is
concerned?

Custom Referrer for Unit Tests?

[Rob P]

I am writing an application that tracks URLs and stores different
information about them (ie URL, referrer, user agent, etc...).

Currently I am writing unit tests for it and I need to be able to
spoof the referrer to test functionality (I only want to log specific
referrers).
Is there anyway I can set the referrer to lets say "google.com"?

I am using the Django test client: from django.test.client import
Client
I need to access the correct test view which is why I'm not using any
urllib libraries.

If anyone know how to do this and could impart your great knowledge it
would be much appreciated.

Thanks!
Rob P

Looking at your dpaste entry again it seems you haven't configured the 
cache middleware.

> Here is the ZeroDivisionError, btw:

Installed Middleware:
('django.middleware.common.CommonMiddleware',
  'django.contrib.sessions.middleware.SessionMiddleware',
  'django.contrib.auth.middleware.AuthenticationMiddleware',
  'django.middleware.doc.XViewMiddleware',
  'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware')



Try adding it in your settings.py, e.g:

MIDDLEWARE_CLASSES = (
 'django.middleware.cache.CacheMiddleware',
 'django.middleware.common.CommonMiddleware',
 'django.contrib.sessions.middleware.SessionMiddleware',
 'django.contrib.auth.middleware.AuthenticationMiddleware',
 'django.middleware.doc.XViewMiddleware',

Re: memcache not used?

[Oscar Carlsson]

I can connect to the daemon, and it's memory usage went up a bit (from 0.2%
to 0.4%)
>>> print mc.get('foo')
bar

But after restarting apache and loading the page in a browser, memcache
doesn't get any bigger. And if I restart the memcache daemon and then
restart apache again, memcache stays on 0.2% memory usage - ie, no change :(

I believe you wont see anything on starting apache but rather when the 
server starts serving requests.

Apart from that, can you connect to the memcached daemon from the python 
prompt?

e.g. does something like this work?

import memcache
mc = memcache.Client(['127.0.0.1:11211'], debug=1)
mc.set('foo', 'bar')
print mc.get('foo')

Re: memcache not used?

[Oscar Carlsson]

I've checked the following logs, but nothing turned up:
/var/log/nginx*
/var/log/httpd* (apache)

Previously, when something went wrong with the app, all error messages
appeared in /var/log/httpd-error.log, but this time - nothing.

This is all the output I get when I restart apache (apachectl restart):

[Tue Jul 01 21:46:02 2008] [notice] SIGHUP received.  Attempting to restart
[Tue Jul 01 21:46:02 2008] [warn] (22)Invalid argument: Failed to enable the

[Tue Jul 01 21:46:03 2008] [notice] Apache/2.2.9 (FreeBSD) DAV/2
mod_wsgi/2.0 Python/2.5.2 configured -- resuming normal operations

I also removed all *.pyc after adding 'debug=1'.

CharField as text?

[Stuart Grimshaw]

Is it possible (with newforms) to either display a CharField as just
text, or have it's value used as the label on another field? I'm
displaying names against checkboxes and I want the names to appear as
the checkbox labels (or at least appear like they are)

Any tips anyone?

Re: Development File Structure

[Brian Luft]

You need to either copy the python executable to a directory on the
Windows system path (C:\windows\system32 for example), or add the path
to the Python installation (often C:\Python25 or similar) to the PATH
environment variable.

Your indentation is wrong. was_published_today is an inner function of
__str__ instead of being a class method of its own. 'def
was_published_today' should have the same indentation as 'def __str__'

Please be very careful with whitespace when writing python/django code!


Btw, are you using version 0.96.x of Django or a SVN checkout? You
should use __unicode__ instead of __str__ in code written for a current
version of Django. This does not matter for the problem you run into,
I'm just asking.

I created instances of SpecialProcess and added them to a Sample.

I have many child classes of Process, and in the field "processes"
instances of all of them should reside next to each other.  Indeed I
can add arbitrary child classes to a Sample via the admin interface,
however, sample.processes.all() yields only instances of Process.

Indentation is significant in Python.  You need to un-dent
was_published_today() so that it is indented just as far as the def
__str__(), not nested inside __str__().

Hi,

this is a limitation of relational databases. Polymorphism and
relational databases do not go well together.

You can try accessing the process.specialprocess attribute -- if this
process was indeed a SpecialProcess model, you'd get back the
SpecialProcess class, and an error in every other case.

Please note that this is documented behavior:

Tutorial method was_published_today() - problem

[[EMAIL PROTECTED]]

Hello,

I'm just going through this tutorial and the custom method
was_published_today() is not recognized as an attribute of Poll,
though it's defined in the model as follows:

from django.db import models
import datetime

class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('date published')
def __str__(self):
return self.question
def was_published_today(self):
return self.pub_date.date() == datetime.date.today()


class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(maxlength=200)
votes = models.IntegerField()
def __str__(self):
return self.choice

Here is the shell output:

>>> from mysite.polls.models import Poll, Choice
>>> p = Poll.objects.get(pk=1)
>>> p.was_published_today()
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'Poll' object has no attribute 'was_published_today'

Re: Polymorphic model: many-to-many is not properly resolved

[Richard Dahl]

In your example SpecialProcess inherits from Process and Sample has a M2M to
Process, where should the SpecialProcess come in?
Is this what you mean:
   class Sample(models.Model):
   processes = models.ManyToManyField(SpecialProcess)

If you do this, you should get SpecialProcess from

 print process.__class__.__name__

otherwise, I do not know how SpecialProcess is supposed to fit in to Sample
at all.

initializing a model with a dicitonary

[[EMAIL PROTECTED]]

I have an object called customer that I trying to initialize from a
large XML parse.  I parse the XML into a dictionary into something
like

customerdict = {'first_name' : 'mike', 'last_name' : 'c', 'etc' :
'etc' } and so forth

then I try to do c = Customer(customerdict).save()

I get a "Can't Adapt" error.

However, if I manually pass in each variable like so:

c = Customer(first_name = customerdict['first_name'], last_name =
customerdict['last_name']).save()

it works fine.

Passing in each variable would be a huge PITA plus any changes to the
model would require changes in multiple places while parsing and
passing the dictionary wouldn't require any changes.  What am I doing
wrong?

Polymorphic model: many-to-many is not properly resolved

[Torsten Bronger]

Hallöchen!

I use the current SVN version of Django.

Consider the following models:

class Process(models.Model):
...

class SpecialProcess(Process):
...

class Sample(models.Model):
processes = models.ManyToManyField(Process)
...

Then I populate one sample with a lot of SpecialProcesses.  Now,
when I try to walk through the processes of this sample with

for process in sample.processes.all():
print process.__class__.__name__

I get a lot of "Process" instead of "SpecialProcess".  Apparently,
the popymorphic many-to-many relationsship is not fully resolved.
Am I doing something wrong or is it a limitation of Django?

Tschö,
Torsten.

This is actually a system problem, not a Python or Django one. Either
the path to the python executable is not in your system's PATH
environment variable (most probably), or you don't have the right to
execute it (but I think you'd have a different error message then). I
haven't use any Windows version since the nt4 days so I couldn't say
for sure how to fix this, but this should be in your system's
documentation.

Re: Need help filtering a queryset

[Brandon Taylor]

Thanks very much for the advice Brian. I'll definitely switch that up
and try both approaches. I hadn't seen another way to get at a subset
of objects other than:

model_set.all

but now I do, thanks to your example.

Kind regards,
Brandon

Re: Need help filtering a queryset

[Brian Luft]

Another approach would be to add a method to your events model. Name
it something like "current_occurrences" and have it return the
filtered occurrences. Ex:

class event( models.Model ):
   ...
   def current_occurrences( self ):
   return
self.occurrence_set.filter( date__gte=datetime.datetime.today() )

Then you would change your template to

{% for occurrence in event.current_occurences %}

That should offer a little better performance since you wouldn't be
pulling the entire occurrence set for each event.

If performance is a major factor, investigate writing a custom model
manager for your events model.  That might be the best option for
retrieving the joined set of events with current occurrences in one
fell swoop in a nice abstracted manner.

The python-memcached client fails silently if it encounters an error, 
e.g. can't connect to the server.

You could try changing how the client is created in
django/core/cache/backends/memcached.py

from:
self._cache = memcache.Client(server.split(';'))

to:
self._cache = memcache.Client(server.split(';'), debug=1)

And see if you get some error message in the server log.

Re: Need help filtering a queryset

[Brian Luft]

Ok, you are asking for a list of events that have occurences on or
after today's date.  Then with each event instance you are asking for
ALL occurence instances (event.occurrence_set.all). ALL means EVERY
occurence associated with that event object.  You haven't done
anything to filter out occurrences based on date in that step.

Re: Need help filtering a queryset

[Brandon Taylor]

I made a custom filter that tests for the date:

import datetime

from django import template
register = template.Library()

@register.filter('is_current')
def isPast(occurrence):
if occurrence.date >= datetime.datetime.today().date():
return True
return False


which works, but is this the best way this can be handled? I'm still
relatively new to Django, and I can't help but think this can be
handled at the Database API level in some way that I'm overlooking.

Thoughts? Advice greatly appreciated.

Heh, ops!

That was a typo, but even after fixing it, nothing changed :(

Need help filtering a queryset

[Brandon Taylor]

Hi everyone,

I have Events and Occurrences of an Event. Occurrence contains a
foreign_key for the Event.
In my template, I need to display the Event and Occurrences as such:

Event Title One
June 1, 2008 [times]
July 23, 2008 [times]

Event Title Two
August 25, 2008 [times]
September 1, 2008 [times]


But, I only want to display dates that are greater than, or equal to
today. In my view, I am selecting Events as such:

events_list =
events.filter(occurrence__date__gte=datetime.datetime.today())


Here's my template code:

{% for event in events_list %}
{{ event.title }}
  {% for occurrence in event.occurrence_set.all %}
  
  
  {{ occurrence.date }}
  
  
  {% endfor %}

{% endfor %}


Which is showing ALL of the occurrences, not just the ones with a date
greater than today. Given the sample data set above, it shouldn't
display the event for June. Can someone please help me out with this?
I'd really appreciate some advice.

TIA,
Brandon

Writing tests for views that use built-in decorators

[Manoj Govindan]

I routinely write views which use two built-in decorators, viz.,
login_required and transaction.commit_on_success. I am able to easily
write test cases for the former. A typical test case looks like this:

self.client.logout()

response = self.client.get(reverse('my_view'))
redirect_url = 

self.assertRedirects(response, redirect_url, status_code=302,
target_status_code=200)

Similarly is there is any way to write test cases for views that use
commit_on_success? I know that the decorator works as intended :) but
I would still like to write test cases if possible.

Regards,
Manoj

Re: Development File Structure

Any 3rd-party Python package or module that you intend to use needs to
be on the Python path.

The Django documentation actually provides some instructions on how to
accomplish this:

memcache not used?

[Oscar Carlsson]

Hi!

For some reason, django doesn't seem to add anything to my memcache - the
process is using 0.2% RAM (seems to be the absolute minimum on my system,
FreeBSD 7 with 512 MByte RAM) and never starts using more memory.

Why is this? I have no idea where to begin debug this, nothing ever shows up
in any logs :/

This is how I've configured my django app (in settings.py):

CACHE_BACKEND = 'memcached://127.0.0.1:112211/'
CACHE_MIDDLEWARE_SECONDS = 60 * 60
CACHE_MIDDLEWARE_KEY_PREFIX = ''
CACHE_MIDDLEWARE_ANONYMOUS_ONLY = True

>From ps -aux:
nobody 54585  0.0  0.2  3204  1240  ??  Ss6:22PM   0:00.01
/usr/local/bin/memcached -p 11211 -m 32 -l 127.0.0.1 -d -u nobody

I'm using nginx as a frontend for a Apache 2.2 (with event-worker, not
prefork etc) using mod_wsgi and a few virtual hosts (although it shouldn't
matter?).

I tried to use this: http://effbot.org/zone/django-memcached-view.htm , but
I end up with a division by zero exception when the view tries to calculate
the memory usage, which seems to be because memcache isn't caching anything.

Anyone experienced this before, or know where to start debug?

Oscar

The problem is with the {% for m in p.members.all %} line, where the
manytomanyfield members gets resolved.  When I comment out that for
loop things are fine.  I have no problem doing this in the django
shell:

>>> for p in Project.objects.all():
>>>   p.members.all()

But it causes a FieldError in the template only on production (apache/
mod_python) which is running MySQL4 while my dev has MySQL5.  I will
try a recent copy of the db to see if it's something in the db.  Also,
I made a UserProfile model change since I upgraded to queryset-
refactor/trunk which consisted of doing OneToOneField(User,
primary_key=True) ...

Regex assistance

[mike171562]

Hello,
   I am trying to build a regex for a query that excludes local phone
numbers from a list of calls thus leaving only long distance.  I dont
have alot of experience with the "re" module

local numbers start with 281, 832, 713 , or 1281, 1832, or 1713, my
regex which isnt working looks like this


Calls.objects.exclude(dest_number__iregex=r'^1?(?=281)|^1?(?=713)|^1?(?
=832)')

The MacPorts version of python doesn't install hashlib in the default  
install.
You need to specifically install py25-hashlib.

Re: combining unrelated tables

[Richard Dahl]

Not sure exactly where you are going, but what do you mean by ' Inside
views.py it only lets me send 1 queryset to the template'  why can't you do
something like:

render_to_response('Template.html', {'first_qs': Model1.objects.all(),
'second_qs':Model2.objects.all()})

What I do is either create a test user on SetUp(), or put that

combining unrelated tables

hey, i searched around this forum and found a lot of questions similar
to this, but i couldnt find an answer to my question.

I need to send data to my templates that comes from multiple tables in
my database. Inside views.py it only lets me send 1 queryset to the
template, so i figured the only way to send data from more than 1
table was to join everything i needed into a single queryset. however
i cant figure out how to join tables within django. is there a way to
do this? and if not is there another way to solve my problem? thanks

I think this is normal.  The only time I recall seeing tracebacks in the
Apache logs is for errors that Django didn't successfully "handle", that is
things like a missing 500.html template -- stuff that causes an exception to
get thrown out to mod_python/Apache and causes its error handling to get
involved.  Django's method for 'recording' the traceback is to send it in an
email to the IDs listed in ADMINS in settings.py,.

generating tables and forms at runtime with the django subsystem

[José Moreira]

hello,

i'm a recent django developer. Sometime soon i will have to develop a
module for a cms solution to allow the content publishers to design
custom forms (including form layout) for webpages and to store the
results of the data of those forms.

the most obvious solution is to keep the form fields properties
(fk_form_id, field_id, label, type, length, required, order) in a
table (form_field) and the input data (fk_form_id, field_id,
user_answer) in another (form_field_answer).

The form itself (html) would be generated at runtime in the
front-office based on the form field properties and an action would
valdiate and capture that data (the POST) and save it to the database.

All of this completly detattched from a data model. The only data
model would the one required to save the form properties and user
input for that form.

The downfall of this is that:
- server-side validation has to be done manually
- the form controls html have to be coded manually using if's (if
field type is BLAH then show html for a BLAH input)
- all the user inputs for all forms are kept in a single database
table that can grow exponentially.

What i'm thinking about, if possible, was to keep only the form_field
table and with that data, generate a data model object on-the-fly (for
each form of course, with TextField, CharField, ..., properties and so
on) and use the django sub-system to (like if it was hard-coded the
usual way) :

- generate the SQL for the form table
- present the CRUD in the backoffice
- validate the datamodel after POST
- use django-forms in the front-office to generate the controls html,
by replacing tags like {FIELD_LABEL:field name 1} and
{FIELD_INPUT:field name 1} in a template with django-form widgets and
showing the result


because in not yet acquainted with the django code base, i'm asking
for your opinion.

thanks


display the form in the front-office by merging

Ok, so I now got the LogLevel debug output.

It says

[Tue Jul 01 07:39:08 2008] [debug] core.c(3027): [client 130.226.238.69]
r->uri = /php/drmu/sommerspil/login/
[Tue Jul 01 07:39:08 2008] [debug] core.c(3033): [client 130.226.238.69]
redirected from r->uri = /php/drmu/sommerspil/login/
[Tue Jul 01 07:39:08 2008] [debug] core.c(3033): [client 130.226.238.69]
redirected from r->uri = /php/drmu/sommerspil/login/

and so forth..

when I hit my url directly at http://77.66.32.232/php/drmu/sommerspil/ ,
I get the expected behaviour of no listing allowed, and I can also
directly access files in that directory that I know exists. So the
redirection is correct.

However, as soon as I try to hitting one of my methods, e.g. 
http://77.66.32.232/php/drmu/sommerspil/login/ then I got the
LimitInternalRecursion error. Please note, that I already tried setting
the limit higher, just in the unlikely case that I wasn't dealing with
infinite recursion.

The relevant section in my apache setup looks like

 
SetHandler python-program
PythonPath "sys.path +
['/home/dradmin/wwwroot/php/drmu']"
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE sommerspil.settings
PythonDebug On
 

And my urls file look like

from django.conf.urls.defaults import *
from sommerspil.spil.views import *

urlpatterns = patterns('',

(r'^/php/drmu/sommerspil/',include('normal.root.urls')),
   (r'^register/','sommerspil.spil.views.register'),

   (r'^setupdatabase/',
'sommerspil.spil.views.setupDatabase'),

   (r'^/php/drmu/sommerspil/login/', 
'sommerspil.spil.views.loginUser'),

   (r'^setroute/$',  
'sommerspil.spil.views.setRoute'),

   (r'^updatetonextday/$',  
'sommerspil.spil.views.updateToNextDay'),

   (r'^(?P.*)$', 'django.views.static.serve',
{'document_root': '/home/dradmin/wwwroot/'}),
   )

I really hope some one can help, as I seem to be running out leads.

Missing traceback for 500 errors

[Elizabeth Kellner]

The full python traceback is missing from my apache logs.  In fact,
I've just seen that the only notification of a 500 error is in
access_log and the browser.  Can anyone suggest any place to look to
see why this is the case?

Here is the python view that I am using to test...
def view500(request):
"Throws a server 500 error for testing"

msg = "Test 500 error.  This is not a real malfunction"
logging.error(msg)

ERROR] Test 500 error.  This is not a real malfunction

I receive my rendered 500.html template in the browser.

(One potentially funky thing I must mention is that I am using the
drlog middleware (http://www.fairviewcomputing.com/blog/2008/03/05/
django-request-logging/), but I tried commenting it out from my
MIDDLEWARE_CLASSES, and the problem persists.  The log message changes
format, but still no traceback.  I doubt this is the cause.)

I'm running Django trunk, revision 7629, on Mac OS X Leopard.

Thanks for your replies,
Elisabeth

I don't have time to look at this at the moment (I'm up to my armpits in
somebody else's problem), but this looks like a bug. Would you mind to
open a ticket and include your example so it doesn't get lost? You can
probably leave out EditableItem, since an example that's as small as
possible if preferable.

All the fields of all the ancestors should be available on any given
model, regardless of any mixing of abstract and non-abstract
inheritance.

Malcolm

Restriction of Model Inheritance - mixing multi table and abstract

[Ian J Cottee]

Take this simple models file. If I try and do

pi = PlayableItem(funfactor=33,code='PS2',description='Play station 2')

I get

"TypeError: 'code' is an invalid keyword argument for this function"

If PlayableItem inherits directly from Item, this does not happen. Is there
some rule I'm breaking here?

Cheers

Ian

--- Code follows ---

from django.db import models
import datetime
# Create your models here.

class BaseModel(models.Model):
"""Abstract class used for some common fields"""
created_at = models.DateTimeField(blank=True,
default=datetime.datetime.now)
modified_at = models.DateTimeField(blank=True,
default=datetime.datetime.now)

class Meta:
abstract = True

class Item(BaseModel):
"""Everything in the system"""

code = models.CharField(blank=True, max_length=15) # A shortname
description = models.CharField(blank=True, max_length=50)

class ValuedItem(Item):
"""This is an abstract base class for stuff with a value"""

value = models.FloatField(default=0.0)

Re: User Authentication - index/base

[Julien]

Ok, then are you passing RequestContext to the template?
A possibility is that your 'user' variable is parasited by another one
in the context.
I guess 'request.user' would do the trick...

GeoDjango/GoogleMaps: No support for points/markers

[[EMAIL PROTECTED]]

I  noticed that the automatic Google Map creation in the Django GIS
branch does not support the display of point features, only polylines
and polygons.

Unless there was a specific reason not to include this, I have a
patch  that will include points as GMarkers on maps, which I could
contribute.

Maybe the reason is that there is not consensus whether Google Maps
should be in the core Django offering?

Re: dreaded FieldError (used to be KeyError) can only replicate on production, ugh!

[Scott Moonen]

Milan, I took another look at the error and your template.  Judging from the
error (it seems to be complaining about some access to the member object,
rather than the project list), I think the reference to line 9 is a red
herring.  In other words, the outermost tag that Django is rendering at the
time is your outer for loop, but the real problem is occurring in the
rendering of an inner loop.

So I'd ignore the reference to line 9 and look further at the inner contents
of that for loop.  I don't think the entire for loop is included in the
dpaste traceback snippet, as I don't see its endfor.

Re: a recent update broke form.save(commit=False) on FK fields

[omat]

More specifically, I think the problem is in
ReverseSingleRelatedObjectDescriptor in related.py, where it does not
check if commit=False at line 249:

...
if value is None and self.field.null == False:
raise ValueError('Cannot assign None: "%s.%s" does not
allow null values.' %
(instance._meta.object_name,
self.field.name))
...

This error suggests the "album" is None. Django raises an error for that
situation now (since it always was an error). So you need to investigate
why "album" would be None there.

That change was checked in on June 5 (it was r7574).

Malcolm

XMLField not working

[Alex Rades]

Hi,
I'm trying to use an XMLField in latest nfa but it doesn't work at all (it
doesn't do the validation).
The code in validators.py/RelaxNGCompact is not executed at all, so this
field is pretty meaningless at the moment.
Do you know why this field is not working?

I updated Django to svn trunk v. 7811 from about a week old version.

When saving a form (ModelForm instance) with a foreign key to another
model, this used to work:

photo = form.save(commit=False)
photo.album = album
photo.save()


But now it raises a ValueError at the form.save(commit=False):

ValueError: Cannot assign None: "Photo.album" does not allow null
values.

Re: requiring fields in the admin page

[Julien]

By default all items are required. To make a field optional you have
to use blank=True.
Some interesting reading here:

Re: a thread problem or my bad codes?

[pength]

sorry for the bad indent of the "#models.py" part. I post it again,
hope this time that part will be shown OK.

#models.py
class Apple_For_Sale(models.Model):
price = models.PositiveSmallIntegerField()
has_been_sold = models.BooleanField(default=False)

class People(models.Model):
money = models.PositiveSmallIntegerField()

def buy_apple(self,apple): #apple should be an instance of
Apple_For_Sale
if self.money >= apple.price and not apple.has_been_sold:
self.money -= apple.price
self.save()
apple.has_been_sold = True
apple.save()
Sale_Records.objects.create(apple=apple,people=self)

class Sale_Records(models.Model): #create one record when one people
buy
apple = models.ForeignKey(Apple_For_Sale)
people = models.ForeignKey(People)
dealt_date = models.DateTimeField(auto_now_add=True)
