Re: Shift a QuerySet?
Good point, that's actually kind of embarassing. I don't actually
expect to be able to use that syntax but I thought it would be
constructive.
Let me try again:
I have a QuerySet of PlaylistAggregation objects. Each
PlaylistAggregation object is related to one Playlist object. I want
to change my QuerySet to select only the related Playlist objects.
An analogous operation would be:
playlist_aggregates = PlaylistAggregation.objects.order_by('-count')
playlists = [p.playlist for p in playlist_aggregates]
But there are some significant downsides for doing that...namely, the
playlist_aggregates QuerySet is evaluated (if I want to paginate the
results, use generic views, etc. it becomes much harder).
Thanks for your help,
Eric

unbound method get_profile()
Hey all, I feel like I may be missing a small thing, but here it is. from django.shortcuts import render_to_response from django.template import RequestContext from django.contrib import auth def profile(request): template_name = 'user_profile.html' obj_list = User.get_profile() return render_to_response(template_name, locals(), context_instance=RequestContext(request)) Simple enough. But when I try to render the page, I get: unbound method get_profile() must be called with User instance as first argument (got nothing instead) I have AUTH_PROFILE_MODULE set correctly, and I can pass normal user data through to the page fine. Any ideas? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Shift a QuerySet?
Thanks!
All of your workarounds involving filter didn't work, erroring with
"Cannot resolve keyword 'song_aggregation' into field", which makes
sense since I really wanted to go the other way around, I think.
Anyways, after some munging with 'extra', as per your suggestion, I
got it working!
Thanks again,

Oops, that should read "Cannot resolve keyword 'playlist_aggreation'

playlist aggregations :)

Re: There's got to be a better way
I'm probably doing something wrong in my template now, but that
version is only returning one event per region, and the order is
backwards. I tried .order_by('-start_date'), but it didn't appear to
make any difference.

Interesting... as long as select_related was on there, it only picked
up 4 events. Remove it, and it gets all 13. Weird.
It wasn't anything to do with region, which isn't another table, it's
just a field under Club with choices (since they'll basically never
change)

Re: There's got to be a better way
Thanks, Tim. I got tripped up by a punctuation, and only half
understood what you were doing, but it put me on the track. Here's
what I ended up with:
future_events = Event.objects.filter(start_date__gte=now)
regions = (
'Pacific',
'Rocky Mountain',
)
events = []
for region in regions:
events.append((region,
future_events.filter(club__region=region)))
return render_to_response('clubs/events.html', {'events': events})
Then in the template, I have a simple check to see if there's anything
there:
{% for region in events %}
{% ifnotequal region.1.count 0 %}
{{ region.0 }} region
{% for event in region.1|dictsort:"start_date" %}
blah blah blah
{% endfor %}
{% endifnotequal%}
{% endfor %}
Carl, I may be mistaken, but I think filter is lazy?

Re: problem with session persistence
What about setting session variable to None, then setting it back to a
new list object with the questions in it, just to see if it's a
problem with it not realizing that the list has been modified?
I don't think this is the best solution either, but would be a good
test to see if it's just not realizing that the variable has changed,
and possibly another workaround if it works.

Re: problem with session persistence
You might want to try adding:
request.session.modified = True ( or modify your settings file to save
every request by setting the SESSION_SAVE_EVERY_REQUEST to True )
Because from this note from Django Session docs:
# Session is modified.
request.session['foo'] = {}
# Gotcha: Session is NOT modified, because this alters
# request.session['foo'] instead of request.session.
request.session['foo']['bar'] = 'baz'

Forms for complex model hierarchies
Hi group, I have a rather complex hierarchy of models. Say, I have a model A. A has a 1:N relation to model B, which itself has a 1:N relation to model C. What I want is a single web page, on which an instance of A and all its related B and C instances can be edited. What is the best way to achieve this? I am not sure wether it is worth the effort of coding something generic like a deepform function. What are your experiences?

Re: problem with session persistence
I just realized that if the above was the case, you probably wouldn't
be getting the NoneType error, but the original list with one element.
Did you check your session contents to make sure the data was in
actually in there? If the new item was there in the session, perhaps
it was your if statement? Did you try
request.session.get('questionlist') instead of if 'questionlist' in
request.session. I would think either would work, but that is worth a
shot as well.

Yup, that's more or less it. event.club is a FK.
Definitely odd, but when I put the select related in, it only finds 4
future events instead of the 13. WIthout it, I'm fine. I can't figure
out where or why it decided to quit at 4, but I'm not sure in this
case it really matters. Since region isn't another table, I'm not sure
what I'd gain by select_related (which admittedly, I don't completely
understand).
But hey, it's working, and it's MILES better than what I had. Thanks
for all your help!

There's got to be a better way
I'm sure you all will immediately see what I'm doing, and how I could
be doing it better. I'm sure I need to create my own dict or
something, but I'm not sure how I'd do so, or (more importantly), how
I'd work with in the template.
In my view, I have:
future_events = Event.objects.filter(start_date__gte=now)
pacific_events = future_events.filter(club__region='Pacific')
rocky_mountain_events = future_events.filter(club__region='Rocky
Mountain')
southwest_events = future_events.filter(club__region='Southwest')
midwest_events = future_events.filter(club__region='Midwest')
central_events = future_events.filter(club__region='Central')
northeast_events =
future_events.filter(club__region='Northeast')
southeast_events =
future_events.filter(club__region='Southeast')
return render_to_response('clubs/events.html', {'
'pacific_events': pacific_events,
'rocky_mountain_events':rocky_mountain_events,
'southwest_events':southwest_events,
'midwest_events':midwest_events,
'central_events':central_events,
'northeast_events':northeast_events,
'southeast_events':southeast_events,
})
And then in the view, I spit out:
{% if pacific_events %}
do stuff
{% endif %}
For each event type, ad nauseum. It works, but I know I'm being stupid
here and thoroughly violating the DRY principle. Could someone show me
the light?

filter by if object exists
I just know this is a dumb question, and I've seen this done
somewhere, but what I'm after is something like
GpUser.objects.filter('image'=True)
To only get the Gpuser objects that actually have an image, rather
than all of them. Can someone point me in the right direction?

Thanks Gary, but it's just one page, and a fairly specialized one...
although I left it out of the above code, there's also a form to
submit events, and the template creates calendars for them.

friends table adding choices from the same database
i'm working on an app that has a table called friends whose model looks like this: class Friend(models.Model): user = models.ForeignKey(User) friend = models.CharField(maxlength=100) status = models.CharField(maxlength=1,choices=FSTATUS_CHOICES) def __str__(self): return self.friend user is the user that added the friend, while friend SHOULD be the id of the user that has been added. Both fields use the user table. I cant use the same foreign key for both, this would be an error. Ideally i would want a drop down box with all the username for the friend field. I thought about using choices, but cant seem to create a tuple that is dynamically populated from the username field in the user table. Any ideas how i could go about this? P.S is this a recursive relationship? i dont think so but hopefully some DB guru can shed some light. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Looping through my POST data?
I'm not sure if I'm following what your saying...but this is what I
think you want to do:
if request.method == 'POST':
pads = request.session.get('pad', [])
for pad in pads:
if request.POST[pad.id] <> '---': # the select
name should be the pad id based on your template code
# do something here ... because it wasn't

Generating charts with ReportLab
I had the need to generate a few different types of charts using ReportLab. The wiki only had a sample of a Horizontal Bar Chart, so I've added a new sample on how to produce a Line Chart... http://code.djangoproject.com/wiki/Charts If anyone is interested in a sample for a Pie or Scatter chart, let me know, and I can add samples of these as well. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Looping through my POST data?
Greg... I'm curious as to why you're iterating over the entire
request.POST when you could just use the id of each pad that you've
previously passed to your template to retrieve it from the
request.POST dict, as that is what you've named your select statements
with?
While iterating through all of the request.POST key/value pairs works,
if you choose to later add any other inputs to your screen that aren't
drop downs for your CarpetPads, you'll have to add special code for
each of them so that your code won't attempt to add a RugPad for those
key/value pairs. Just wanted to point that out, in case you might
need to do that later.

Re: Looping through my POST data?
Right... because, unless I'm misunderstanding your code... you're
creating a select drop down for each of your RugPad entires with the
RugPad id. So you know that the request.POST is going to have entries
for each id...
But..I think it should be this:
opads = RugPad.objects.all()
for a in opads:
if request.POST[a.id] != 0:
opad = RugPad.objects.get(id=a)
s = opad.size
p = opad.price
pads.append({'size': s, 'price': p})
So now you'd be iterating through each of your rug pads, and checking
to see if the corresponding drop down had a non-zero value selected,
instead of iterating all of the request.POST keys. This way you can
have other items in your form if needed.

Re: Is there any way to associate a view with a template?
Why not have a base template that contains the menu variable ( I put
mine in a session variable accessible to the templates named menu ),
then have all of your other templates extend from that template?
In base.html:
your header code
{% block menu %}
{{ menu }}
{% endblock%}
{% block content %}{% endblock %}
Then in your other templates:
{% extends "base.html" %}
{% block content %}
content for your html specific page here
{% endblock %}

Re: Is there any way to associate a view with a template?
Yeah I was going to post a sample if that's what he said next :) Here
is another sample in addition to the link above .. on how to pass the
menu code via context processors:
In your settings.py file ...
Find the line that says (there may be more in there depending on your
setup):
TEMPLATE_CONTEXT_PROCESSORS =
("django.core.context_processors.request",)
Change it to something like this:
TEMPLATE_CONTEXT_PROCESSORS =
('yourproject.yourapp.somepythonfile.menu',"django.core.context_processors.request",)
Then under in your python code create a menu function which
corresponds to the above:
def menu(request):
return {'menu': "some html code for the menu"}
Then when calling up each of your views add
(context_instance=RequestContext(request)) when calling
render_to_response:
return render_to_response('somefile.html',
{'someothervariableyouyoumightwant':value},context_instance=RequestContext(request))
Now you can access this via {{ menu }} in any of your templates.

How do I echo template variables?
I'm coming from CakePHP and I would typically set a variable for use in my view with a call to findAll. Since there is a lot of data in the array, I typically do something like: This way, I can find out what data is available in the view and figure out how much I can scale back the recursion. Is there any equivalent in Python/Django?

Re: PopUp instead of Select widget (newforms)
I am not using new forms... but I'm assuming you would make this a text field... with a link next to it that says something like 'view existing entries' Then when a user clicks that, you could do one of the following: 1. Display a ldiv with a list of all entries, and make it so that when the user scrolls through the list and clicks on one, it closes the div, and sets the text in the entry box ( if you need the ID of what is selected... you could do this in an invisible form field ). 2. Display a search box, then post a form submit back to the same page, with parameters set so that it comes back with matching results displayed, each as a link to hide the div and set form variables as described above. 3. Display a search box, and use AJAX to pull back the matching results, with a list displaying matching results, each as a link to hide the div and set form variables as described above.

Newforms and GET Requests for Search Result Pagination?
Greetings, Is it not possible to use Newforms with GET requests? I'm trying to figure out how to paginate results from a search form, and I'm passing GET values to the pagination view, instantiating an instance of the Form object with request.GET as an argument (instead of the typical request.POST). I can't find any mention of GET support in the documentation, is this something that will eventually be added or has it been decided against? Also, does anyone know of any very clean way to paginate search results? I really can't believe there's no way to do this with generic views, it's a common thing to have to do. It's no good if you lose your search query every time you change pages :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I completely forgot to run is_valid() on the receiving view, so cleaned_data wasn't being populated. This was the problem. Thanks!

Traversing Deep Model Objects in template...
I'm using the Books, Publishers, Authors example from the
documentation (Django Book) and I'm trying to figure out how to get
related data in a list. For example, I want to print a list of books
and a list of authors for each book in my template. What do I have to
do to make the code below function?
view.py
...
def index(request):
books = Book.objects.all().select_related()[:3]
return render_to_response('books/index.html', {'books':books,})
...
template.py
...
{% for book in books %}
{{ book.title }}
{% for author in book.authors %}
{{ author }}
{% endfor %}
{% endfor %}
...
Thanks in advance!

Re: Traversing Deep Model Objects in template...
Is this the *best* way to accomplish this? It seems like the author DB
query per book isn't very efficient (where it might sense to do a
JOIN) Also, if I was doing any more "levels" things would get very
complicated and bloated.
view.py:
...
def index(request):
data = Book.objects.all().values('id','title',)
books = []
for b in data:
book = Book.objects.all().get(id=b['id'])
authors = book.authors.all().values('first_name','last_name',)
books.append({
'id': b['id'],
'title':b['title'],
'authors':authors,
})
return render_to_response('books/index.html', {'books':books,})
...
template.html:
...
{% for book in books %}
{{ book.title }}
{% for author in book.authors %}
{{ author.first_name }} {{ author.last_name }}
{% endfor %}
{% endfor %}
...

Dojo LayoutContainer and ContentPane as application frame?
Hello Group,
I tried to setup a kind of frame architecture with the dojo layout
container widget.
The idea is to load the menu (fisheye widget menu) only once and let
the django page itself load asynchronously into a ContentPane.
A dojo menu widget loads an url in the content pane like this:
function load_app(id){
var docPane = dojo.widget.byId("docpane");
if (id == 6) {
docPane.setUrl("/projects/");
}
}
Projects is an application of my site. The main urls.py includes the
url of the projects application:
(r'^projects/', include('mugdisite.apps.projects.urls')),
The project app urls.py has the following:
.
info_dict = {
'queryset': Project.objects.all(),
}
urlpatterns = patterns('',
(r'^$', 'django.views.generic.list_detail.object_list',
dict(info_dict, paginate_by=10)),
...
The urlpatterns work ok when I enter localhost:8000/projects directly.
However, in the dojo ContentPane the result is "Error loading '/
projects/' (200 OK)".
When I modify the main urls.py to direct to a HTML template directly,
the inclusion works
(r'^projects/', 'django.views.generic.simple.direct_to_template',
{'template': 'projects-entry.html'}),
Do you think it is somehow possible to trick the dojo widget which
expects a HTML file, I think?
I am using the django trunk version and dojo 0.4.
Would be happy for any help.
Dennis

AttributeError: 'module' object has no attribute
Hello, I keep getting this error and I can't seem to track where it is coming from. I am working with django-0.91. I had a calendar app that was installed but I commented calendar out in my installed apps and commented it out in the urlpatterns. So there should be no reason why this is trying to load this module. Could the error be coming from somewhere else. I entionally placed errors in the settings.py and urls.py file to see if it would trip up on that and it doesn't even make it to that point. I am stumped and don't know where else it could be erroring out at.

Re: Dojo LayoutContainer and ContentPane as application frame?
ok the solution was
dojo.io.bind({
url: "/projects/",
load: function(type, data, evt){ docPane.setContent(data); },
mimetype: "text/html"
});
sorry ...

Making get_or_create (or equivalent) atomic on MySQL
Hi, I'm trying to atomically check if a certain field in the db exists and create it otherwise. I naively started using get_or_create but it seems like that function does not try to do things atomically at all. My database is MySQL and my table type is InnoDB. I installed the select_for_update patch and was calling select_for_update().get_or_create(): Tag.objects.select_for_update().get_or_create(name = tagName) This gave me a deadlock when run from multiple threads. I also tried select_for_update().get() with a try except on DoesNotExist and then calling create separately: try: Tag.objects.select_for_update().get(name = tagName) except Tag.DoesNotExist: Tag.objects.create(name = tagName) I still get a deadlock. It appears that MySQL does not create the exclusive lock on the row in Tag because it does not exist yet. Is there a good way (simple or not) of performing this operation (get_or_create) atomically, even if it is MySQL specific. I appreciate any help!

Re: Including view in a template
In the view.py code that you have calling your
frontpage_template.html, you should put your code to query the
database and generate your user list and articles. You would then
pass these to your html template via:
return render_to_response('frontpage_template.html',
{'list_users':list_users,'latest_articles':latest_articles})

Re: Including view in a template
Another option is to use AJAX to populate the "building block" areas.
e.g. (Using JQuery)
$(document).ready(function() {
$('#block1').load('/views/list_users');
$('#block2').load('/views/latest_articles');
});

Compare column entries in database query
Hi everybody! I want to find all entries in a database where two specific fields are equal: mytable.objects.filter(column_a='column_b') But this gives me no results at all. I now managed to get it done with a .extra(), but I was wondering if this is the only possible solution. All examples in the documentation work with static values for comparison and there are no further details about the right hand side of the query. Thanks for reading! Thomas.

Job Fair F/OSS project
I'm looking for some volunteers for a new open source project. At the Institute of Design (http://www.id.iit.edu ), our next project is a system for the management of our job fair (http://www.id.iit.edu/ recruitID/ ) The systems goal is to allow students and employers to enter their availability for interviews and have the system designate times and rooms for each to meet for interviews. The system includes much more than just this of course, but that is the main goal. We decided that this application is generic enough that it should be made into an F/ OSS project. So far the system will be built on Django and uses (hopefully) Prototype.js I've only really been using Django for a month now so anyone with real experience would be appreciated. The project is on the ground floor and some basic wire frames and a few other preliminary designs. I'm personally located in Chicago and West Virginia (about half of my time spent in each place), though you are welcome to help out from anywhere around the world!

.. would hit the DB again .. but requires little code.
Post back if another hit isn't a viable option and we'll take a closer
look at the problem.

Only save if changed?
In my site_users model (which extends auth user), I've got: def save(self): self.geocode = self.get_geocode() super(SiteUser, self).save() # Call the "real" save() method. get_geocode makes a call out to google's geocoding service, gives the city and state, and returns the geocode. Since there's a lot of activity on site_users, updating for board post counts and all sorts of other things, I don't want to call get_geocode unless city and state have actually changed. Is there a way to check if they've changed. I know there's an ifchanged filter for templates, but don't know about this. Or should I move it to the update profile view, and only get geocode when they actually update their profile? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Job Fair F/OSS project
Well, all that stuff is still up in the air. This is the very-very beginning of the project. I think the first thing I'd like to do is to setup a site, like google code or sourceforge. If anyone has a suggestion about which one is better, that'd be great. I know they all use SVN (I use Git), so that's not a factor. It's also possible for me to just setup a Trac site (I'm most likely gonna setup one anyhow) like I've been using with my previous internal projects and forego sourceforge and google code.

css 404?
I've got a seemingly simple setup that I'm having problems with. The
urlconf is:
==
from django.conf.urls.defaults import *
from django.views.generic.simple import direct_to_template
urlpatterns = patterns('',
# Example:
# (r'^home/', include('home.foo.urls')),
# Uncomment this for admin:
(r'^$', direct_to_template, {'template': 'home.html'}),
(r'^admin/', include('django.contrib.admin.urls')),
(r'^blog/$', include('home.blog.urls')),
==
I have a template directory having home.html in it. home.html has
, but the
server always 404s the css _only_, whether it is written as home.css
or ./home.css.
Emphasizing here that home.html and home.css are in the same directory
but the server is not finding the latter.
Is this a problem wih direct_to_template? Should I be using a simple
view? Or django.contrib.flatpages?
Thanks!

login issue
Hi,
I just read chapter 12 in djangobook.com on authentication:
http://www.djangobook.com/en/beta/chapter12/
I am creating a new user in response to a registration form I've made,
doing something like this:
from django.contrib import auth
from django.contrib.auth.models import User
def createAccount(request):
# extract information for PUT form request
# ...
newUser = User.objects.create_user(username_, email, pwd)
newUser.save()
auth.login(request, newUser)
return HttpResponseRedirect('/userHome/')
But there is an exception with the login. Apparently the user doesn't
have a backend, as shown below.
Thoughts?
Thanks,

Maps / Variables in template system.
Hi I'm working on a project, where I have several items in a database with x and y coordinates. I want to plot these out in such a way that if there is not an item for a space, it shows a blank image in the table, and a corresponding picture if there does exist an item. However, in the template system, due to a lack of the ability to change variables, I'm not sure how I can do this. If theres a snippet somewhere that I couldn't find for just an increment tag, I'd be fine.

Re: How to add a javascript calendar to date textboxes
I've done that, and it's not hard, but there's quite a few good js
datepickers out there, and on my most recent one I used one of
those gives me a bit more control over how I want it to look on
the public-facing part, and I'm not making 5 http calls to do it.
Here's the one I went with:
http://www.frequency-decoder.com/demo/date-picker-v2/
And again, it's just adding a class to the input.

Re: Why aren't my flatpages working?
I believe so. There's only one, and the domain matches the site domain. In the DB, it has the ID 1. Not seeing anything wrong there.

The true minimum permissions for your DB are not dependent entirely on Django -- what you plan to do with the particular application you build using Django is just as important. Obviously, when you run syncdb to create tables from ORM, you are going to need to give the django user CREATE permission. Don't know if there are cases where it would use ALTER. Once the tables are created, you can revoke the user's CREATE, ALTER, and DROP perms. All tables are going to need SELECT; so far as I know, none of them are going to need SHOW. Most tables will need INSERT, but not necessarily all -- suppose you have a table that is populated by a different app, and all Django does is consume the data. You may or may not need DELETE for any given table, again depending on how you plan to use it. As with any serious security issue, there is no quick easy right answer. The safe bet is always assume your setup is insecure, unless you have solid reason to believe otherwise. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Access the request object in a filter?
Hey All,
I'm trying to create a 'shopping' website, and one of the design
elements that is necessary is that the "Purchase this item" link
changes to a "Remove this item from your cart" link when the item has
been added to the user's Shopping Cart.
When an object is added to the shopping cart, a ShoppingCartItem
object is created (this is necessary to allow for things like
quantities, item discounts, shipping calculation etc...), and I need
to tell whether a ShoppingCartItem the exists for a particular Item
(fk'd to the user's ShoppingCart).
Everything works great apart from this bit. I know that I can make a
template tag that has access to the request object (added by the
Context Processors), but am a bit stuck as to how to do this in a
filter. Ideally I would like to do something like:
{% if item|in_cart %}foo{% else %}bar{% endif %}
So, all I really need to know is how I would get access to the request
object in a filter. I haven't tried it, but don't think
{% if item|in_cart:request.session.cart %}
Would work. Any help in getting access to the request (or session)
data in a filter, or a better way if anyone can think of it, would be
much appreciated.
Kind Regards,
Oliver

Re: Is this not allowed select_related()
He means that you can remove: employee = models.ForeignKey(Employee) from your 'EmployeeAssignment' and 'EmployeeContract' models because the relationship is already defined in your 'Employee' model. You can use reverse relations to get the relation instead.

[Q] Django with modpython in Ubuntu
Dear all,
I have a problem using mod_python with Django (v 0.95) under apache2
in Ubunu.
I followed all the steps described in the online documentation, but it
did not work.
The followins is how I set up the httpd.conf and error message I got.
httpd.conf:
DirectoryIndex index.php index.html index.htm
AcceptPathInfo on
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonDebug On
PythonPath "['/home/yjlee/Worx/Django/Projects'] + sys.path"
I created a project with "django-admin.py startproject mysite" at "/
home/yjlee/Worx/Django/Projects" directory.
When I pointed my web browser to "http://edtech.soe.ku.edu/mysite/;
I got the following error messages:
Mod_python error: "PythonHandler django.core.handlers.modpython"
Traceback (most recent call last):

self._cookies =
http.parse_cookie(self._req.headers_in.get('cookie', ''))

File "Cookie.py", line 451, in set
raise CookieError("Illegal key value: %s" % key)
CookieError: Illegal key value: hide:inst11
Can anyone help me solve this problem?
Thanks in advance.

ReStructuredText, markdown and other
I'm watching on some light markup languages that can be used in Python - what they can and what they can't do. I'm planning to use one in a "sandbox" on my sites and more or less in other apps with some extra plugins. Markdown: + simple, easy to understand + there is showdown - markdown in JS so online preview :) (http:// www.attacklab.net/showdown-gui.html) - limited syntax (no tables) - hard to extend ReST: + powerfull syntax + rather easy to extend - not so obvious syntax in some places - errors on bad syntax Textile: + powerfull syntax + looks quite good ? never used it, ? are there some extras ? Currently I'm on Markdown + my template filter on top of it buy maybe it's better to use python-born ReST?

MediaWiki Port in Django - Project Interest?
I've got a project where I need to build a public wiki for some community websites. The main requirement is that the functionality be similar to Mediawiki since many people are familiar with the way that software works. Does anyone know if a project like this has been undertaken? Would anyone be interested in helping develop it? Would anyone be interested in using it if it was released as a contrib app? (Before anyone asks why I'm reinventing the wheel, I don't use PHP anymore, I don't have PHP installed on my production servers, and I want to use a common authentication system that is already in place with my very large Django project) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Feed question
I have an events model, and a feed for it - shows all events
Events has a foreign key relationship with Club. What I'd like to do
is have a feed for each club, but I'm not sure how to get that into a
feed without explicitly defining it for each club.
Say I have two clubs, Foo and Bar, I want something in feeds.py like:
def items(self):
return Event.objects.filter(club=theClub).order_by('-created')
where theClub is Foo, or Bar, or whatever.
Can I do this with the built-in feeds framework?

Google Checkout w/out a shopping cart?
I'm trying to build a very simple ecommerce page using Google Checkout
without the use of a shopping cart. Here are my models:
class Team(models.Model):
name = models.CharField(maxlength=30, unique=True)
def __str__(self):
return self.name
class Meta:
ordering = ['name']
class Admin:
pass
class Association(models.Model):
name = models.CharField(maxlength=30, unique=True)
def __str__(self):
return self.name
class Meta:
ordering = ['name']
class Admin:
pass
class OrderForm(forms.Form):
association =
forms.ModelChoiceField(queryset=Association.objects.all())
team = forms.ModelChoiceField(queryset=Team.objects.all())
I'd like users to be able to select their association and team from a
drop down list, and send their selection immediately to Google
Checkout without the use of a shopping cart.
Is there a way to capture their selection and send "team" as the item-
name, and "association" as its description? Here's my view function
so far:
def order(request):
order_form = OrderForm()
return render_to_response('order.html',
{'order_form': order_form})
And here's how I'm currently trying to send the info through Google
Checkout:
Right now, when I send this to Google Checkout, instead of sending the
name of the Association and Team that was selected, it sends the word
"team" as the item-name, and "association" as the item-description.
Please let me know if you have any insight!
