Re: trying to do console testing of my models, "no module named X"
If you do: python manage.py shell you will get a python shell with all the necessary paths set up so that you can do your testing. You may also want to consider some sort of automated testing as it makes this sort of thing a lot easier and quicker.

Re: noob syntax question
I'd add to Michael's comment that if you're unhappy with this syntax (I personally find it a bit odd in some cases), you can customize exactly what word is used there in your model definition. If you alter the choice model and add the "related_name" keyword to the foreign key definition, e.g.: class Choice(models.Model): ... poll = models.ForeignKey(Poll, related_name="choices") you can then do: >>> p.choices.create(...)

Re: Generate image and send to template
I can't understand the comments in your code, but it looks like some graph generating software. I think the problem you're having is that the first function returns a HttpResponse half way through (line 53), but then there is some further processing which will never be accessed. The second function expects some data by calling the first which never seems to return it in the correct form for further manipulation and so that's why it's not working. I'd be quite concerned about writing to a file from a web app on your disk. If you want to store the data somewhere temporarily, I'd consider either a temporary file or pickling the data in a database.

Quote: "To order by a field in a different model, use the same syntax
as when you are querying across model relations. That is, the name of
the field, followed by a double underscore (__), followed by the name
of the field in the new model, and so on for as many models as you
want to join." (5th para under the "order_by" section)

Re: M2M with Intermediary - Django Admin Support - Doesn't appear?
heya, Nuno: Thanks for the advice. I know how to add normal inlines to the home page for a model, via the "inlines" list in admin.py. However, how exactly do I add an inline formset to the Add Article page? I can override the template for the Add Article page, however, I don't think that's what needs to be done here. Is there a clean way of using the existing "Add Article" page, but just swapping in an inline for the intermediary? Also, I'd like to leverage off the exisiting "filter_horizontal" widget, if possible. Basically, I just want it exactly as it was, without the intermediary, with a filter_horizontal for settings the m2m relationship, but then with just an additional widget for setting the intermediary "rating" field. (I found this write-up http://www.fictitiousnonsense.com/archives/22 however, it seems geared towards replacing a single field on a single model, not sure how it'd handle the intermediary model here. Also is this method still valid/best practice?).

Deployment hesitation after James Bennett's post, WSGI or ...?
I'm about to enter my first deployment learning curve, but after reading James Bennett's post 'Let’s talk about WSGI' (http://www.b- list.org/weblog/2009/aug/10/wsgi/) and further procrastinating by reading through a whole pile of (horribly varying) tutorials and WSGI guides, I'd like to know: 1. what the Django deployment wisdom is for the near future? 2. whether it's really worth running lighttpd (or whatever) for static files on small-scale sites (say, where there's just a blog and a few rarely-altered pages)?

How do i test django ratings in my project?
Hi, I have installed django ratings application in my project http://github.com/dcramer/django-ratings Am wondering how best can i test my app voting functionality, because django ratings is only allowing me to vote only once for the same user, object and Ip address. Is there a way i can disable this checks so that i can just insert votes, test my application and when am happy i can enable this checks back. e.g. you can only run this once in the same machine; myobject.rating.add(score=1, user='user_name', ip_address='127.0.0.1') Again the user need to have been authenticated, unless you use None, but again only once.

Re: Django Sphinx or haystack Xapian
We are in the process of switching from a custom Xapain installation to Solr as we found Xapian quite limited in its ability to do faceting, spelling suggestions, or highlighting. If you don't need any of those things, I would recommend Xapian (although I've not used it through Haystack). I have used Haystack with Whoosh and agree that Whoosh needs a fair bit of work yet. That said I do like the haystack idea. Solr is really good for what we want and is really powerful, but we have had to allocate it 1.5GB of memory for reindexing! I have no experience of sphinx, but from what people have said above it seems like a good solution.

Well, I had to get something up-and-running, so I have fallen back on the "don't try this in your app" method of threads.

problem deserialization
Hi,
I am working on implementing a REST web service example of booking a
hotel. It was supposed to be simple to start with but I am already
badly stuck:)
I am stuck with deserialization and serialization. I want to create
a new resource when PUT is requested on booking. My GET method works
perfectly fine but I am stuck with PUT. My code on method PUT is:
def do_PUT(self):
try:
deserialized = serializers.deserialize("json",
self.request.raw_post_data)
put_book = list(deserialized)
except (ValueError, TypeError, IndexError):
response = HttpResponse()
response.status_code = 400
return response
for obj in put_book:
b1 = guest( fName = "hello", phone = 21, email =
"t...@email")
b1.save()
json = serializers.serialize("json", b1)
response = HttpResponse(json, mimetype="application/json")
response.status_code = 201
response["Location"] = "/bookings/%s" % (b1.id)
return response
Now when I send PUT request via curl, i.e.:
curl -i -d "{'room_id': 21, 'payment_id': 21, 'guest_id': 21}" -X PUT
http://127.0.0.1:8000/bookings/
It gives me 400 error, i.e. HTTP/1.0 400 BAD REQUEST
This means it is raising and exception and not able to deserialize the
data.
I tried removing the statement: put_book = list(deserialized) in
try block. ie,
try:
deserialized = serializers.deserialize("json",
self.request.raw_post_data)
# put_book = list(deserialized)
except (ValueError, TypeError, IndexError):
response = HttpResponse()
response.status_code = 400
return response
for obj in deserialized:
b1 = guest( fName = "hello", phone = 21, email =
"t...@email")
b1.save()
json = serializers.serialize("json", b1)
response = HttpResponse(json, mimetype="application/json")
response.status_code = 201
response["Location"] = "/bookings/%s" % (b1.id)
return response
It then doesnt raises and exception but gives 500 error: HTTP/1.0 500
INTERNAL SERVER ERROR
.
Exception Type: ValueError at /bookings/
Exception Value: Expecting property name: line 1 column 1 (char 1)
...
In line 1 of my views.py, I am just importing : from django.http
import HttpResponse, HttpResponseNotAllowed, HttpResponseForbidden
And there is no problem in this line, since my rest of the views
perfectly fine if its not for this problem.
Any help and input would be appreciated. I am stuck in this for last 2
days and trying to fix it. I have googled extensively but still no
clue.
Thanks,
Irum

It happens rarely, randomly (although it might not be really random) and currently I don't have idea what to look for to fix it (it also doesn't have high priority for me, but if some of you knows this problem then I'll be happy to fix it sooner than later). -- Tomasz Zielinski http://pyconsultant.eu -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: About raw sql query
but it is only a simple query, why don't you use the query api (aggregate

.raw() is new in 1.2.
But if you just want the max ID, you don't want raw anyway. This is
better:
InfantRegistration.objects.order_by('-id').values('id')[0]

The line1, column 1 refers to the JSON file, not the code. Your JSON
is not valid. Try putting it through a validator like
http://jsonviewer.stack.hu/
to see what's wrong.
That said, if you want to create a RESTful API in Django, the work has
already been done for you: just use django-piston.

Manager's get_query_set are cached ?
Hi, I'm banging my head against the wall with an issue in get_query_set. I'm using django 1.2.1 and I'd like to filter the queryset results through a date within get_query_set. However, I noticed that with the dev. server or gunicorn, the get_query_set is only called on the first request. This manager is called from a queryset passed to a generic function so unless those functions have builtin cache, I don't understand why the get_query_set is only called on the first request. Has anyone an idea why this happens ? Regards, Xavier. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: noob syntax question
Thanks for the feedback and the link, all good stuff! I looked at what i had written, and I think a better way to ask the question is: What are the mechanics behind providing "choice_set.all()"? For example i have a field "choice" so having "_set" (concatenated) is that generated when i run syncdb somewhere, or is that dynamically interpreted at runtime? My background leads me to think there would be a choice.set().all(), the "_set" seems weird (to me) unless its generated.

Fields can define a 'contribute_to_class' method, which is responsible for defining dynamic properties/methods on the model class. When the field is instantiated - which happens when the class is defined, ie when its module is first imported - the field's contribute_to_class method is executed and the related manager is created. You can see the code for this in django.db.models.fields.related.RelatedField. (Actually you'll see that contribute_to_class calls do_related_class, which calls contribute_to_related_class, which sets up the descriptor on the related model.) A very good guide to all this is Marty Alchin's book Pro Django, which goes into depth as to how the model metaclasses work. -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Content types and interaction with DeferredAttribute models
I have the same problem. It looks like the content types app will return
the content type of the original model when asked for one since revision
10523 (see ticket #10738), but that an additional content type is still
created.
Is the creation of the additional content type necessary?

Hi,
How about not in?
Select * from tableA where columnA not in

null=False, blank=True and errors saving in admin?
Upgrading from Django 1.0 to 1.2, I'm suddenly getting errors when
creating objects in the admin form a class that essentially looks like
this:
class MyObject(models.Model):
name = models.CharField(max_length=50)
other_thing = models.ForeignKey(MyOtherModel, null=False,
blank=True)
def save(self, *args, **kwargs):
logging.debug('saving here')
if not self.other_thing:
other_thing = MyOtherModel()
other_thing.save()
self.other_thing = other_thing
super(MyObject, self).save(*args, **kwargs)
Creating a MyObject in the admin and leaving the other_thing field
blank results in the following error:
Cannot assign None: "MyObject.other_thing" does not allow null values.
The logging statement is never being hit, so it looks like the over-
aggressive validation is being performed in the ModelForm. What am I
doing wrong?
Thanks!

mod_python is dead. you can just serve your static files .. statically. usually you might point at a cdn or put nginx in front although you could set /media or / ash/media to serve statically with apache.

Re: Manager's get_query_set are cached ?
Thanks for your answer Daniel.
I also though about mutable variable as default paramter but I doubt it is.
Indeed, I should have pasted the code from the start, so here we go.
Note that those are parts of the django-cms blog plugin called cmsplugin-blog
(http://www.django-cms.org/en/extensions/?page=3)
In urls.py, I have:
blog_info_dict = {
'queryset': Entry.published.all(),
'date_field': 'pub_date',
}
and in the url pattern:
(r'^$', 'django.views.generic.date_based.archive_index', blog_info_dict,
'blog_archive_index'),
Then, in the published manager:
def get_query_set(self):
now = datetime.datetime.now()
print now
return super(PublishedEntriesManager, self).get_query_set() \
.filter(is_published=True, pub_date__lte=now)
My issue is, with the dev server or with gunicorn, I only have the "print now"
for the first request. Whenever I reload the page, I can't get it again, I have
to restart the server.
I know django-cms uses cache. However, debug-toolbar tells me that the request
is being processed so I assume it is not cached.
Would it be possible that it only caches one part of the queryset ?
Regards,
Xavier.

Re: null=False, blank=True and errors saving in admin?
Thanks, that didn't show up in my search, but it's exactly the same
traceback.
The ticket description seems to indicate the bug only applies to
testing situations, but clearly it occurs in the default ModelForm
(and thereby in the admin) any time a foreign key is set to
null=False, blank=True. Leaving a field blank and filling it in in
the model's save() method seems to be a pretty common case, and I
would think should be allowed without creating a custom ModelForm.
Should this be listed somewhere as a backwards-incompatible change,
since it worked in 1.0?

m2m with intermediary - model design? Disappears from Django-Admin?
heya, NB: This is a followup to this: http://groups.google.com/group/django-users/browse_thread/thread/0fdc1dfb1fddb97b/6b559dc4abf5d4ea but I thought I'd also ask about the model design. To provide some background, we have a Django app that contains a list of journal articles. Each "Article" also has a m2m relationship to "Firm" as well as "Spokesperson" class Article(models.Model): title = models.CharField(max_length=100) publication_date = models.DateField() abstract = models.TextField() # Can we restrict this to 450 characters? ...fields ommited for brevity... firm = models.ManyToManyField(Firm, null=True, blank=True, through='FirmRating') spokesperson = models.ManyToManyField(Spokeperson, null=True, blank=True, through='SpokespersonRating') The intermediary models, FirmRating and SpokespersonRating look like this: class FirmRating(models.Model): firm = models.ForeignKey(Firm) article = models.ForeignKey(Article) rating = models.IntegerField() Basically, we use it to store the m2m link, as well as a "rating" assigned to each relationship. The issue is, as soon as I change it from a normal m2m relationship to one with a "through" attribute, it seems to completely disappear in the Django Admin from the "Add Article" page. Before, I had a nice little filter_horizontal widget to create the relationships. No, zippo...that's not a bug, is it? Anyhow, Firstly, am I doing this the right way? Or is there another way to create an Article, have it m2m with Firms/Spokesperson, and assign an individual rating to each relationship? Secondly, is there some way of making a m2m with intermediary visibile in the admin - is it intended behaviour for it to disappear? In an ideal world, I'd like to have the filter_horizontal, as well as an inline widget to set the rating, all on the "Add Article" page. However, I'm prepared to have just the filter_horizontal for the m2m, and set the rating separately, on a separate page just for FirmRating/ SpokespersonRating (it obviously breaks the workflow a bit there). How do people normally deal with editing m2m intermediary models in Django? Cheers, Victor -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: m2m with intermediary - model design? Disappears from Django-Admin?
heya,
Also, I should add I did try using the inlines as described in the
docs
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#working-with-many-to-many-intermediary-models
In my admin.py, I've imported "FirmRating" at the top.
I've then created an inline for it:
class FirmRatingInline(admin.TabularInline):
model = FirmRating
extra = 1
then used this in ArticleAdmin:
class ArticleAdmin(admin.ModelAdmin):
#inlines = [
#CategoryInline,
#]
date_hierarchy = 'publication_date'
filter_horizontal = ('firm', 'spokesperson')
list_display = ('title', 'publication_date', 'entry_date',
'category', 'subject', 'source_publication', 'weekly_summary')
list_editable = ('publication_date', 'category', 'subject',
'source_publication')
list_filter = ('publication_date', 'entry_date', 'category',
'subject', 'source_publication')
search_fields = ('title', 'publication_date', 'abstract',
'category__name', 'subject__name', 'source_publication__name',
'page_number', 'url')
However, there's still no visible widget for "FirmRating" on the "Add
Article" page.
I can't tell just from the docs, but is this inline only for use on
the main Article list page, but not on the Add Article page? Or is the
above admin code meant to make the widget visible on the "Add Article"
page as well?

Re: m2m with intermediary - model design? Disappears from Django-Admin?
heya,
Ok, scratch all that, I'm an idiot.
A simple restart of my Apache process, and the m2m intermediary inline
works *grins*.
Thanks anyhow to the awesome Django community for an awesome tool =).
I do have a final question though. I can now edit "Firms" as inlines
from the "Article" page, which is good.
However, to be honest, the filter_horizontal widget was a much better
interface. I suppose there's no way to somehow use the
filter_horizontal widget within the inline, and then tack on a
"Rating" field as part of the inline?
Also, I notice that in my inline, it says "FirmRating object" right
above the select box:'
http://twitpic.com/1zo4im/full
Any way to hide/tweak that text?
Cheers,
Victor

Re: m2m with intermediary - model design? Disappears from Django-Admin?
Gday Victor,
Glad you found the inline admin method for attaching your m2m's with
throughs. It isn't possible to to use the filter_horizontal widget for
through m2m, because, as you noted, there's no space for the extra
fields to be input. You could always try to extend the widget, but
this is more trouble than it's worth, and I haven't seen it done
acceptably. If you don't like all the space taken up by the inline,
try making them collapsible with js, maybe (you can define js in the
ModelAdmin inner class Media:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-media-definitions).
As for the name "FirmRating object", define a unicode method on your
class, eg:
def __unicode__(self):
return "%s - %s: %s) % (self.article, self.firm, self.rating)
Cheers,
Brenton

process_response not getting called in custom middleware.
Gday folks,
I've written a middleware to add some session variables based on the
request variable; this is done in process_request, which always
returns None. I'd like to set some cookies as well, based on the same
session variables, which should be done in process_response. I wrote
the method, but found it was not dropping cookies, so I simplified it
some, here is my current version:
def process_response(self, request, response):
"""Drop cookies based on whether a user has selected an
offer
Always drop (refresh) the greencode cookie and RefCode
cookie
Drop offer cookies based on whether the user has clicked-
through on
an offer.
"""
print "BAH!"
#if request.session.get('grc'):
#response.set_cookie('_gc', request.session['grc'],
31536,
#domain=domain)
#response.set_cookie('RefCode',
request.session['refcode'], 31536,
#domain=domain)
return response
This, unfortunately, doesn't print anything to the server log (either
when running the development server, or on an apache/mod_wsgi
environment). Even when I change response to an empty HttpResponse(),
I still get the response the view returned. So surely this all means
that the process_response method is not being called.
Does anyone have any suggestion as to why this might be happening, and
how to rectify it?
Thanks,
Brenton

Re: Admin Media output order?
Gday, Overriding the admin templates is the only way to do this: http://docs.djangoproject.com/en/1.2/ref/contrib/admin/#overriding-admin-templates You can either try listing the items how you want (this will mean a change to the templates everytime you register something new), or doing it using JS (you'll prolly have to change this whenever you register something new as well). I generally opt to set verbose_names on my models, so that they get listed into groups, eg: Offer Banners Offer Sidebar Banners Referers - Domain Referers Referers - Search Engine Referers Referers - URL Referers It's the cleanest way I've found to do such a thing.

Re: m2m with intermediary - model design? Disappears from Django-Admin?
heya,
Brenton: Thanks for the reply =).
Hmm, I was hoping to use the filter_horizontal widget to set the
relationship, and just have a box below that for setting the rating.
But you're right, we'd need a table for each rating for each
relationship, and there's a room issue.
I might look into extending the widget - is there any good
documentation on extending Django admin widgets? I saw this article:
http://www.fictitiousnonsense.com/archives/22
but I'm not sure if that's still up-to-date, and I was hoping for more
details/examples to learn how to do it well. Any good reading
recommendations on this topic?
Also, it's not so much an issue with the inlines taking up space, as
that the filter_horizontal widget, with the in-built search box, the
"choose all" and "clear all" links is just a good UI, and looks quite
nice, to boot. I'd really like to integrate it in somehow to the
inline if possible...lol.
Anyhow, finally, thanks for the tip about __self__, completely didn't
think about that. Will set that now.
Cheers,
Victor

reloading in shell
hi, when I run python manage.py shell, I find each time there is a change in code or an error I have to exit the shell and re enter it.

Re: m2m with intermediary - model design? Disappears from Django-Admin?
Gday again Victor,
If you think about it, the filter_horizontal widget really doesn't
make sense in this context, because selecting multiple objects to link
to will still require a list of them somewhere (as you mention) to set
the rating. Since you like the searchability, perhaps adding an
autocomplete to the inline admins would be helpful? I'm not a huge UI
guy though, so maybe you're just more imaginative =D If you come up
with anything, let me know.
In terms of resources, all I can recommend is reading through the
source. Sorry about that!
Best of luck,
Brenton.

ModelChoiceField
Hi all, is there any way to use the ModelChoiceField without any value in it? I tried to set query = None but it gave an error while rendering the html page -- You received this message because you are subscribed to the Google Groups "Django users" group.

Rendering the Admin app list?
Working with Django 1.2.1
The default index page for Django admin contains:
{% if app_list %}
{% for app in app_list %}
...
{% endfor %}
{% else %}
{% trans "You don't have permission to edit anything." %}
{% endif %}
I'd like to move this snippet to a separate page; however, when I do
so, nothing shows up (well, the page template "wrapper" is there, but
no listing of models etc.)
What do I need to do to enable this?
Thanks
Derek
