Messages framework not including tags

[bax...@gretschpages.com]

I've read the 
docs: https://docs.djangoproject.com/en/1.3/ref/contrib/messages/

I have the MessageMiddleware in place.

I have the SessionMiddleware in place (before MessageMiddleware)

django.contrib.messages.context_processors.messages in in the context 
processors

django.contrib.messages in in installed apps.

Template has the standard messages code:

{% if messages %}

{% for message in messages %}
{{ message 
}}
{% endfor %}

{% endif %}


I'm getting the message(s), but there is no tag associated. What am I missing?

Re: Custom admin changelist queryset

[bax...@gretschpages.com]

> Can you tell us what you goal here is?

The goal is to get my combined list of featured items to a changelist
page. From there, I'll have additional work to do, but step one is
getting it to the page at all.

Another thought is to just chain the querysets together and send 'em
to my own template. It would look like part of the admin, but not
actually be part of the admin. Problem there, of course, is that if I
wanted actions, list display, or any other admin-y goodness, I'd be
out of luck, I think.

Custom admin changelist queryset

[bax...@gretschpages.com]

I'm trying to combine a subset of two models and pass them to an admin
change list:

class FeaturedItemsAdmin(admin.ModelAdmin):
   def queryset(self, request):
   qs1 = Foo.objects.filter(featured=True)
   qs2 = Bar.objects.filter(featured=True)
  . do stuff to combine ...
  return combined


I can return qs1 or qs2 to the admin, no problem. But I can't put them
together in a way the admin will accept.

First thing I tried was a simple itertools.chain. I've also tried
building a custom queryset (http://djangosnippets.org/snippets/1933/)
and subclassing queryset. At best, I get nothing, but most times I
get:

"Database error
Something's wrong with your database installation. Make sure the
appropriate database tables have been created, and make sure the
database is readable by the appropriate user."

Which I've tracked down to a IncorrectLookupParameters exception in
contrib.admin.options, but that doesn't really help me figure out what
it is the admin wants that I'm not giving it.

If you're on Django prior to 1.3, you probably want the simple
direct_to_template generic view (which does still work in 1.3):
https://docs.djangoproject.com/en/dev/ref/generic-views/?from=olddocs#django-views-generic-simple-direct-to-template

If you ARE on 1.3, make sure you're importing TemplateView before you
try to use it.
from django.views.generic import TemplateView

Also, if you are going to do it all with template tags, watch your
queries. I think it's easier for them to spiral out of control with
template tags.

Not exactly, no. In my particular case, it's more of a check to see if
it's available, and if not, do a bit more work to get something that
will fill the current need. Or, in other words, maybe I'm storing it
locally, or maybe I'm not.

Another example:

{% with firstof obj.votes obj.get_votes as votes %}
Which would then let me do something with votes: "There have been
{{ votes }} vote{{ votes|pluralize }}.

Re: Is there a standard way to implement the top level of my site?

[bax...@gretschpages.com]

I've had per-project views (in the project root), I've had apps
feeding indexes, and I've gone direct to template using template tags
to fill in snippets needed. Most times -- but not always -- the last
approach seems the most flexible and easiest.

Re: Django for a front end designer

[bax...@gretschpages.com]

I came into Django as a designer. It can be done, just take baby
steps. The more python you learn, the happier you'll be, and the more
productive. But in the mean time, you can do a lot with generic views
and reusable apps that would keep you from having to write much code
at all. I would suggest finding Jeff Croft's Django for designers blog
post from a few years back. It's a little out of date, but still worth
reading.

And that works, with one

Getting the objects IS a bit inefficient, but since I only need the

Getting "most"

[bax...@gretschpages.com]

I have a "watch" model that lets users keep an eye on various things
through a generic relation:

class Watch(models.Model):
subscriber = models.ForeignKey(User, verbose_name="Subscriber")
content_type = models.ForeignKey(ContentType)
content_object = generic.GenericForeignKey()
object_id = models.IntegerField('object ID')
created = models.DateTimeField(auto_now_add=True)


What I'm trying to do is get the most-watched objects.
I saw James Bennett's snippet from 2007 (http://djangosnippets.org/
snippets/108/) which looks like it would work (subbing my Watch model
for comments), but I'm wondering if there's a better way to do it with
newer versions of django, possibly through annotate or aggregate?

Tom, I initially thought it was an nginx thing as well, but I don't
believe so any more. I don't think that would explain why it fails on
this topic EVERY time, and every other topic NONE of the time. I think
the failure to load some static media is a sympton, not the actual
problem. Turning sendfile off did not change the behavior at all.

Plus I have no errors in my nginx logs. Problem is, I can't find
anything about that particular topic that would cause any problem.
That topic (and a couple of others) will error every time, while all
the other pages on the site don't, ever.

I do think whatever it is, it's very low in the stack. Maybe
middleware?

Comes from fontsquirrel. As I recall, it forces the local load if the

I'm pretty sure it's nothing in my styles though, as it has only hit

server connection dropped? IO Error? What's going on?

[bax...@gretschpages.com]

Foolishly posted this late last week, which is a tough time to get
help. Please forgive me for reposting, but I'm at my wit's end here.

What I've got is a very localized, yet apparently completely random
sort of IO error, or something else causing the server to drop out.
You can see an example here:
http://gretschpages.com/forum/your-tunes/five-min-love-affair/36446/page1/

On initial load, you'll probably see one or two static elements fail
to load.
If you hit reload or follow any link from that page, you'll either get
ALL static media fail to load, or the page will not load at all,
giving some sort of "server busy" message.

That topic will do it every time. Pretty much every place else on the
site will not. The server is not busy, it's something about that
topic, and the handful of others this thing has hit.

I can't find any commonality among the problem topics/posts. All other
posts/topics are fine.
If I copy all the info from the problem topic into a new one, it posts
fine.
If that user posts another topic, it works fine.

Server config is Nginx is handling static media and passing django
stuff over to Apache.

I don't see anything in the nginx or apache error logs, and nothing
looks off in the database, either.

Any suggestions on where to look or how to debug this?

Very strange lost network connection problem

[bax...@gretschpages.com]

This is a weird one. On a handful of topics on my forum, accessing the
topic and/or attempting to add a post or do anything else loses the
network connection. It's only on a handful, and it just started
recently. I have no idea how Django can even do such a thing, but you
can see it here:

http://gretschpages.com/forum/electromatics/on-the-2nd-day-of-christmas-my-true-love-gave-to-me/36273/page1/

On initial load, you'll probably see at least a couple of images error
out with a lost network connection error or "Failed to load resource",
depending on what browser you're looking in. Or it may lose all static
media. Hard to tell what it's going to do from one page load to the
next.

If you hit reload, it will probably lose ALL static media.

If you were to try to add a post, it would go to a blank "server
unexpectedly dropped the connection" type of page.

It's just two or three topics. All others are unaffected. Whatever the
problem, it seems to be centered on just these few topics.

Nginx is handling static media and passing django stuff over to
Apache.

I don't see anything in the nginx or apache error logs.

I've looked in the database, and nothing appears out of the ordinary
with these topics, either.

server configuration

I'm using Nginx for static, passing off to Apache/mod_wsgi for django

>From some sources I've seen that is ideal, but I notice in the django
docs that prefork MPM is better. But then I read you can't use prefork

Legacy URLs redirect

I'm sure this is simple and I'm just not constructing the URL
properly. Basically, it used to be a drupal site, with the cruddy old
Drupal every url is a querystring setup. What I want is pretty
simple... all of those old URLs resolve to the home page and send a
301 to the spider.

I tried:
(r'^?q=taxonomy/term/[0-9]+$', redirect_to, {'url': '/', 'permanent':
True}),

And failed most spectacularly. Do I need to be escaping something, or
what am I missing?

admin login problems and 'ValidationError: [u'ManagementForm data is missing or has been tampered with'] '

[bax...@gretschpages.com]

I'm having a lot of staff users having login problems. Until today, it
was only IE, but today I saw it happen to a user on FF as well.

The basic flow is like this: They try to login to the admin. It
appears to work. When they click anywhere, it goes back to the admin
login. This repeats several times, until eventually it fails with
ValidationError: [u'ManagementForm data is missing or has been
tampered with']

It does not matter what project, app or model they are going to. It's
not even the same admin's... it's actually spread across several
projects/sites. The only thing they share is that they're both using
the same basic Django 1.1 install.

Any ideas?

portable apps problem

[bax...@gretschpages.com]

I try to make my apps portable between the various sites/projects that
use them, but I'm running into some problems doing so. I'm hoping
there's some good way to handle this I just don't understand or know
about.

In a nutshell, I've got multiple sites/projects, and I'd like them to
all use the same articles app. Problem is, the articles app was
originally written for site A,and has at least one M2M relationship
with another app that site B does not have, need, or really want. So,
how do I give site A what it needs without cluttering up Site B with a
bunch of unwanted extras, while using the same app?

Problem with DateField input_formats

[bax...@gretschpages.com]

I have:

DATE_INPUT_FORMATS = (
'%n/%j/%Y', '%n/%j/%y',  # '10/25/2006', '10/25/06'
'%n-%j-%Y', '%n-%j-%y',  # '10-25-2006', '10-25-06'
'%M %j %Y', '%M %j, %Y', # 'Oct 25 2006', 'Oct 25, 2006'
'%b %j %Y', '%b %j, %Y', # 'oct 25 2006', 'oct 25, 2006'
'%F %j %Y', '%F %j, %Y', # 'October 25 2006', 'October 25, 2006'
)


class CandidateProfileForm(forms.ModelForm):
class Meta:
model = Person
dob = forms.DateField(input_formats=DATE_INPUT_FORMATS)


But I'm not getting my date format through. For example, 4-20-1990
fails, even though I think it should be covered by %n-%j-%Y

I've also tried:
class CandidateProfileForm(forms.ModelForm):
class Meta:
model = Person
widgets = {
'dob':
forms.DateField(input_formats=DATE_INPUT_FORMATS),
}

with no luck. What am I missing here?

It's definitely port 3306 (double-checked). Not sure about non-local

Server on diffferent machine

[bax...@gretschpages.com]

I know this is something stupid I'm missing, but I'm not getting it.

I'm trying to run my Django from one cloud instance and the DB from
another, to (hopefully) optimize each server for task and balance the
load a bit.

On the DB server, I have mysql installed and have a working database
running on the default port 3306. I do not have a domain assigned to
this server, only a raw IP.

On the django side, I'm not sure what my settings should be to connect
to it. So far, everything I've tried has resulted in
_mysql_exceptions.OperationalError: (2005, "Unknown MySQL server host
'< THE IP >' (1)")

Settings.py looks like:

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django',
'USER': '',
'PASSWORD': 'XXX',
'HOST': '< THE IP >',
'PORT': '3306',
}
}

What am I missing?

What I've found so far (OSQA, Askbot, soclone) are far from pluggable.
I don't want a whole other site, just an app.

Actually, on the first one, I would just define it in the model. So if

   do stuff

and in the template, you'd just say entry.get_comment_count

Re: what lines in the templates are culpable?

[bax...@gretschpages.com]

Without seeing the traceback, this is all just guessing--stabbing in
the dark. But...

a) posting a traceback allows people to actually help not only solve
the problem, but help show how to read the traceback.

b) commenting out template code may have suppressed the problem, but
that still doesn't mean the problem was actually in the template.
Template tags, for example, can throw errors.

Again, without seeing the trace it's hard to say, but it sounds like

Re: get_comment_count templatetag

I'm not saying it's the best way, but I would either define my own
get_comment_count in my application's models.py that looped through
the ojbects comments (and their comments) to get an accurate count.

OR

I would store comment_count locally on the object and send a signal
when a comment is saved, something like (and excuse the pseudo-code)
if this.parent = object or this.parent.parent = object: comment.count
+= 1

Re: Problems with comment form customization ?

[bax...@gretschpages.com]

There are several ways you can do it, but probably the most
straightforward is how django does it in the first place:

{% for field in form %}
{% if field.is_hidden %}
  {{ field }}
{% else %}
  {% if field.errors %}{{ field.errors }}{% endif %}
  
{{ field.label_tag }} {{ field }}
  
{% endif %}
  {% endfor %}

Looping through the fields, and if the field is honeypot, setting
display:none

That's all in django/contrib/comments/templates/comments/form.html

Weird path problem

[bax...@gretschpages.com]

my setup is like this:

/apps/
  /apps/app1/
  /apps/app2/
/projects/
  /myproject/

I've got it set up that way because multiple projects use multiple
apps. Because of that setup, I use django-admin.py, specifying the
project.

Anyways, from the admin and site side of things, everything looks
fine. Installed apps are loading, I see everything in the admin, etc.
My problem is that django-admin.py isn't seeing the apps. For example,
if I run
python django-admin.py sql app1 --settings=myproject.settings

Re: Need limit_choices_to help

[bax...@gretschpages.com]

Looking at this more, I think I may have more of a logic problem

I think Play can't have any idea of Game roster, because until it's
been saved it has no idea what game it's related to. So maybe what I
need is a way to dynamically fill the player field on Play, after game
has been selected. Tips?

Need limit_choices_to help

[bax...@gretschpages.com]

I've got a Players model
I've got a Game models with roster, a M2M relationship with players,
to select the players actually playing in that particular game
And I've got a Play model with a foreignkey to Players. What I want is
to limit the list of players to the ones that are actually on the
roster for that game.

In my head, it should be something like
playmaker   = models.ForeignKey(Player, limit_choices_to=
{'id': 'game__roster'},

Or am I looking at it all wrong? Should I build a choice list from
roster on the fly and use that? OR can I just foreignKey straight to
Game__roster?

Help!

Re: Django and Online Payment Systems

[bax...@gretschpages.com]

I think it really depends on the payment system. Most all of them I've
dealt with have some sort of API. Tap into that, and away you go.
Localizable could be interesting, though, just due to currencies and
such. I built one that handled shipping to different areas (US,
Canada, Intl), but all funds had to be US.

actions and/or customizing the admin best practices

[bax...@gretschpages.com]

I have some admin-y type functions like "import articles from blog"
that currently are called when a particular URL is visited, and I'd
like to integrate them into the admin. My first thought, since this is
on 1.1, was to use actions, but it appears actions can only work when
applied to selected items in the changelist.

While I was looking that up, I saw a suggestion to make it one of the
object-tools buttons, but from there I went down a rabbit hole of new
APIs and other questions centering around what exactly is the best way
to customize the admin these days.

So: currently using 1.1.1 final, but could update to a newer version,
what is the simplest/best way to add my function into the admin?

Thanks Daniel. I figured it out. In some instances stop time didn't
exist, so of course it wouldn't validate as a datetime. Adding a check
to set empty stop times to the start time fixed it.

No it will "create those model tables in your database" ... "for all
apps in INSTALLED_APPS that don't already exist in your database" ...
"and it will only ever create the tables that don't exist."

If the table already exists, you will need to manually modify it. For
sqlite3, I would suggest the Firefox sqllite manager plugin, which
makes editing the tables pretty easy.

syncdb will not alter an existing database. You can run it (it won't
hurt) but it won't insert the new fields. You'll need to go to your
database, either through the command line or through a tool like
phpmyadmin and add the new fields manually. You can, however, run
manage.py sql YOURAPP to see what the table should look like.

image like a local file, and it could disappear someday. I'm trying to
save a local copy of the files, but can't seem to get it working
properly. From what I can tell, I'm copying the file OK, but the image
model doesn't see it.

No, it's not that I can't see them on the site. They're not in the

upload problems

[bax...@gretschpages.com]

Not sure what's going on, but my images aren't uploading.

I'm using the built-in dev server.

I'm on OS X.

I've tried a lot of different things for MEDIA_ROOT. The most recent
is:
MEDIA_ROOT = '/Users//Sites/django-media/'

and
MEDIA_URL = '/media/'

For now, while it's just in test, I have this in URLS.py:

(r'^media/(?P.*)$', 'django.views.static.serve',
{'document_root': '/Users/tbaxter/Sites/django-media/ink/',
'show_indexes': True}),

I've checked permissions on every directory.

When I attempt to upload I get no error.
I see the filename in the admin.
If I click it, I 404. Also, a slash is appended.

If I back up to the /media/img/ directory, nothing.

I'm sure I've just got something configured wrong. I've never used
django on a local machine before, so the paths and such are a bit
different than I'm used to.
Anyone see where I've gone wrong?

Strange upload problem

[bax...@gretschpages.com]

Strange in that it used to work and now doesn't. Unfortunately I only
use it about twice a year, so I'm not sure when it stopped.

Basically, I'm trying to upload a csv and save the fields to the
database:

class SpecialEvent(models.Model):
   ...
   results_csv = models.FileField(upload_to='files/events/special/
results/', blank=True, null=True)
   ...
   def save(self):
if self.id is not None:
old_self = self.__class__.objects.get(id = self.id)
if self.results_csv and (self.results_csv.name !=
old_self.results_csv.name):
for i, line in 
enumerate(open(self.results_csv.name)):
[do stuff]

super(SpecialEvent, self).save() # Call the "real" save() 
method.

I'm getting an IOError: [Errno 2] No such file or directory: u'files/
events/special/results/utcc-results.csv'

When I look in the directory, I see the file. Is it not there yet when
it's trying to open it? Should I maybe use a post save signal or
something instead?

Admin login needs to be https

I don't care if the admin as a whole is https. Honestly, I think I'd

Does anyone know how one would do A/B testing a la Google Website

Trying to figure out "featured for month" view

[bax...@gretschpages.com]

I'm trying to figure out a view for a "featured Foo for ". The
thinking is we'll mark the thing we want featured and which month it
should appear.

So, in the model, I'm thinking featured_for_month with month_choices
being the months and featured for year being something like:
YEAR_CHOICES  = [(str(y), str(y)) for y in range(datetime.date.today
().year, datetime.date.today().year+1)]

then in the view,
have something like
Foo.objects.get(featured_for_year=datetime.date.today().year,
featured_for_month=datetime.date.today().month)

Sound reasonable? Is there a better way to do this?

Problem creating object

[bax...@gretschpages.com]

I'm trying to manually create an object (from a signal). My problem is
that the object has a 'sites' M2M field:

class News_item(models.Model):
...
sites = models.ManyToManyField(Site)
   ...

but when I try to create the object:

news = News_item(
...
sites = site,
..
)

I'm getting a type error
TypeError: 'sites' is an invalid keyword argument for this function

What am I doing wrong here?

Problem querying database

[bax...@gretschpages.com]

I'm hoping someone can help me get the info I'm trying to get. This is
the structure:

I have Categories
Each Category has one or more subcategory
Articles have a M2M relationship with subcategory so they can turn
up in more than one category as needed.

I'm trying to get one random article for each category, but NOT the
two most recent articles.

I'm trying this:

articles = Article.objects.filter(publication='Published',
assigned_to=subcat).order_by('-id')[2:]
subcat.article = articles.order_by('?')[0]

Which should get all the articles for the subcat except the two most
recent ones, then select one random one from that list, except I'm
running into "AssertionError: Cannot reorder a query once a slice has
been taken."

So, how can I do this?

Generating USER documentation?

What I'm after is documentation for the admin users, similar to the

care about views, models and template tags.

Is there an easy way to create/generate such a thing?

User registration issues

[bax...@gretschpages.com]

I have a random/intermittent user registration problem. I can't figure
out any pattern to it, but it appears to have started when I went to
Django 1.0.

Some users (again, it appears random and intermittent) are not getting
a site user profile created. The auth.user profile is created, and the
registration profile (I'm using django-registration) but not the site
user profile. I'd say probably 80% of the registrations go without a
hitch. Of the remaining 20%, almost all of them work on the second
attempt (after I delete the first, failed registration), but a handful
still haven't worked.

I wonder if it may be browser-related. I can register all of these
people myself with no problem using Firefox or Safari.

I'm using an older version of django-registration. I believe it's 0.3
-- it still uses profile-callback. Thinking that maybe there was a
problem with the older version and django 1.0, I figured I would
upgrade to the latest version.

I'm still not sure if that will fix the problem, because I
registrations with the latest version of django-registration are all
failing with "Signal receivers must accept keyword arguments
(**kwargs)" when I follow the activation link.

update facebook status

[bax...@gretschpages.com]

Now that I've got my twitter integration sorted out, I'm trying to
figure out how to update the facebook status, too.  Twitter was
relatively easy. Can someone point me to the how-to on updating
facebook? The catch: it's the status on a product page, not a profile.

Signals, sites and instances

[bax...@gretschpages.com]

Follow up to my earlier question (http://groups.google.com/group/
django-users/browse_thread/thread/8f41540343634178/c05242e6d3b07d62)

As I mentioned there, I'm trying to use a snippet to send a twitter
update when a news item is created. The news items have a M2M
relationship with sites-- news can go on one site or both.

So I need to make sure I'm posting the news item to the correct
twitter account. Based on that earlier question, I have:

if instance.sites.filter(id=1):
   do stuff for first site
if instance.sites.filter(id=2):
   do stuff for other site
else:
   return false

This is failing to post when the news item is first created. If I re-
save the item, THEN it will post. I believe it's because
instance.sites is still an empty list at this stage (not yet been
created).

So what can I do? Is the POST info available to the signal maybe?

Simple sites framework question

dynamic select boxes in forms with jquery

[bax...@gretschpages.com]

I know I've seen this before, so I'm hoping someone can help me find
it again.

I need to dynamically filter a select box in the admin, preferably
with jquery (just because I already have it there and it's available)

What I have is a car makes and models with a many to many
relationship. (Some cars, like the Neon, for example, fall under more
than one make)

When the user selects  the Car (make), I want to only show the models
for that make.

Need help with combined feed

[bax...@gretschpages.com]

I'm trying to build a combined feed, and not having much luck. Here's
what I have:

class CombinedFeed(Feed):
title = site.name +" combined feed"
link = "/"
description = "Latest updates from all "+site.name +" feeds"
description_template = 'feeds/combined.html'

def items(self):
combined = []
articles=   Article.objects.all().order_by('-created')[:
40]
events  =   
Event.objects.filter(start_date__gte=now).order_by
('start_date')[:50]
news=   
News_item.objects.filter(pub_date__lte=now).order_by('-
pub_date')[:20]
combined=   itertools.chain(news, articles, projects, 
issues,
events)
for item in combined:
   try:
  item.date = item.created
   except:
  try:
item.date = item.topic_modification_date
  except:
 try:
item.date = item.pub_date
 except:
try:
   item.date = item.start_date
except:
   item.date = now
return combined


Which doesn't appear to do anything. No error, but no ojb in
combined.html, either.

Problem tapping into Amazon web service

[bax...@gretschpages.com]

This code used to work, but appears to have stopped working at some
point. I suspect it's either a unicode or escaping thing. I'm trying
to use Amazon web services and return books:

amazonfile = urllib.urlopen("http://webservices.amazon.com/onca/xml?
Service=AWSECommerceService=mykey=myID=ItemSearch=myAuthor=Books=Medium").read
()

xml = xmltramp.parse(amazonfile)

for item in xml.Items:
   ""do stuff. For purposes of debugging..."
  print item.ItemAttributes.Title

It fails with "no child element named ItemAttributes"

Looking at the XML, I clearly see ItemAttributes as a child of Items.

When I have it print xml, I'm not seeing an xml format, so that's why
I'm suspecting some kind of unicode or escaping problem.

Thoughts?

Years

[bax...@gretschpages.com]

I need a YearField of sorts, where users can select a year (for their
car), and I'm trying to figure out how best to implement it. I'd need
roughly 1901 to present. I know I could just put them all in choices,
but that seems messy and a pain to maintain (even if only once a
year). Better ways?

My structure isn't quite the same as yours, but in my experience

Re: JavaScript Slider in Django Form

It's possible I don't understand what you're trying to do, but I think
you just need to call the hook into the id of the textfield. If
multiple, set a class attribute in your form setup and hook onto that.

"connect a function to the signal"

[bax...@gretschpages.com]

I'm trying to update from my very old version of django-registration
to .7 in hopes of sorting out some registration issues I'm having.

In my old version, I use the profile_callback to create my site user
profile:
from site_users.views import create_site_user
...
url(r'^$',
   register, {'profile_callback':
create_site_user},
   name='registration_register'),


In .7 the docs say "connect a function to the signal" but I guess I
don't understand.
I have the signal
user_activated = Signal(providing_args=["user"])

and I have my create_site_user function, but I'm not clear on how I
insert tab A into slot B.

I know how stupid I sound. I've looked at the signals docs, I've
looked at the django-registration docs. I know this is simple, but I'm
not getting it.

update_object acting strangely

I think this just started, and may be related to updating to 1.0.2.
Lately I've noticed update_object not updating properly. In

have an "approved" field that's True, but when the user update the
info, "approved" is changing to False. This is happening on at least
two different models, and I've never noticed it until the past week or
so. Suggestions?

OK, where's it picking up the / then?

No / there.

Suspicious Operation/ filestorage problem

[bax...@gretschpages.com]

My SiteUser model allows an avatar upload. If there's not one, it
assigns a default image on save:

def save(self, *args, **kwargs):
 ...
if self.avatar is None:
 self.avatar = "img/avatars/default.gif"

super(SiteUser, self).save(*args, **kwargs)

Pretty straightforward. Problem, is, later when I try to get height of
avatar (siteuser.avatar.height) It fails whenever the avatar is
default. gif with a suspicious operation error:

...
 File "/home/grmadmin/webapps/django/lib/python2.5/django/core/files/
storage.py", line 204, in path
   raise SuspiciousOperation("Attempted access to '%s' denied." %
name)

SuspiciousOperation: Attempted access to '/img/avatars/default.gif'
denied.

I've checked permissions on default.gif, but that doesn't appear to be
it.
I can call siteuser.avatar with no problem, but siteuser.avatar.height
fails every time, if the avatar is default.gif
