Re: sample app for beginner
Chuck,
The Django tutorial should get you going:
http://docs.djangoproject.com/en/dev/intro/tutorial01/#intro-tutorial01
And an app. published earlier on this list:
http://code.google.com/p/django-todo/
Happy coding.

Re: ModelMultipleChoiceField and initial values
Wow this is really screwing me royal. Doesn't work with any form of
select, best I can tell initial doesn't work with ChoiceFields at all.
I've tried going into the source and logging out the value param to
the widget and it is always just [].
Am I on crack, can somebody verify, so I can file a bug report if I'm
not. ( by default these days I just assume I'm an idiot. )

Re: filter queryset in admin
Assuming you're using Django v1.0 ... you could override the queryset method in your class that defines the admin properties for your class. For example: class MyAdminClass(admin.ModelAdmin): def queryset(self, request): # Limit the queryset to some subset based on the value of request.user To see how queryset behaves by default, look at django.contrib.admin.options.py Hope that helps.

Re: Sorting list of objets in Python/Django
You could, but a key function is generally better, and the larger the
list the better (in the general case) it is likely to be. The problem is
that using __cmp__ requires the sort algorithm to make Python callbacks
from a C function for each object-pair comparison. Using the key
function, that function is called once to decorate each object in the
list, and the C sort function compares the decorated list items without
the need to call out to Python functions at all.
As with all general solutions, specific circumstances can alter this
general conclusion.

I was trying to implement previous and next buttons and I found this tutorial: http://www.webmonkey.com/tutorial/Install_Django_and_Build_Your_First_App#Tweak_the_links_and_tags where teach a very interesting way of implement them for date fields but I need to use them for a class that doesn't have any date time fields but is ordered by an integer field. Then, I used ipython to check what methods were available for the object and got curious about _get_next_or_previous_by_FIELD and _get_next_or_previous_in_order But I think I would change my question to a clearer one: How can I easily implement next and previous buttons in my template for a class that does not have any date fields?

Impact of a CustomManager on the RelatedManager
Hi everyone,
I apologise for the verbosity of this message - for my first post it's
quite long.
I am currently working on my first project employing the Sites
framework, and have been moving along quite well with the
documentation until I hit a snag last night.
I have overloaded the default manager in my model to use a slight
variant of the CurrentSiteManager, shown below.
class MyCurrentSiteManager(models.Manager):
def __init__(self, field_name='site'):
super(MyCurrentSiteManager, self).__init__()
self.__field_name = field_name
def get_query_set(self):
return super(MyCurrentSiteManager,
self).get_query_set().filter(**{self.__field_name + '__id__exact':
settings.SITE_ID})
The reason I've trimmed it down, is because I want field_name to be a
site reference on a related model. such as:
class Venue(models.Model):
name = models.CharField(max_length=50)
site = models.ForeignKey(Site)
objects = MyCurrentSiteManager()
systemwide = models.Manager()
class Conference(models.Model):
title = models.CharField(max_length=50)
venue = models.ForeignKey(Venue, related_name='conferences')
objects = MyCurrentSiteManager('venue__site')
systemwide = models.Manager()
What I am seeing is that the following queries work and present only
the objects which are on the site (Venue) or objects which are related
to a Venue on the site (Conference):
Venue.objects.all()
Conference.objects.all()
However, if I try to get the related objects of a Venue object, I get
an error as below:
>>> v = Venue.objects.get(pk=1)
>>> v.conferences.all()
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python2.5/site-packages/django/db/models/manager.py",
line 78, in all
return self.get_query_set()

settings.SITE_ID})

line 483, in filter
return self._filter_or_exclude(False, *args, **kwargs)

line 501, in _filter_or_exclude

query.py", line 1287, in setup_joins
"Choices are: %s" % (name, ", ".join(names)))
FieldError: Cannot resolve keyword 'site' into field. Choices are:
venue, id, title
I added a print line to my manager's get_query_set method, so it now
reads:
def get_query_set(self):
print self.model._meta.object_name, self.__field_name
return super(MyCurrentSiteManager,
self).get_query_set().filter(**{self.__field_name + '__id__exact':
settings.SITE_ID})
When I redo the query above, I now get:
>>> v.conferences.all()
Venue site
Conference site
Traceback (most recent call last):
... as before ...
I was expecting it to be:
>>> v.conferences.all()
Venue site
Conference venue__site
So my analysis is that the RelatedManager (v.conferences) is not
completely partnering up with my MyCurrentSiteManager because,
although the print statements are firing off, they are not actually
using the field_name parameter I supplied when instantiating the
manager on the model.
And here we are, finally at my question! Is it possible to have the
related manager use the field_name that was passed in to my custom
manager?
Again, sorry for the long post but I thought it best to lay it all out
there first!
Regards,
Gary

Re: Adding www. prefix to get_absolute_url
You should instead use named URLs and the
django.core.urlresolvers.reverse function in your get_absolute_url
methods. That way you'll leave it to the URL system to handle. I
believe you shouldn't use absolute URLs (with http:// and domain) at
all. Just make sure in your web server config that all requests to
domain.com are redirected to www.domain.com while keeping the request
path (although I'd rather redirect from www.domain.com to domain.com
because it's cleaner and makes sense).
You should consult the docs about the URL system (reverse, permalink
and the {% url %} template tag).

Adding www. prefix to get_absolute_url
I'm using Django .96 and I'm having trouble getting get_absolute_url
to add a www. prefix on to my URLs.
For the most part everything on my site keeps people on my www. URL,
which is my goal, but my sitemap and RSS feeds point to URLs without a
www. on them.
Does anyone know a good way to fix this?
Here's an example of how my get_absolute_url statement looks.
def get_absolute_url(self):
return "/appname/%s/%s/" % (self.creation_date.strftime("%Y/%b/
%d").lower(), self.slug )

So entry_cat is not a character field, meaning you cannot directly filter on
it with a text value like you were trying to. Instead of:
current_entries =
Entry.objects.filter(entry_cat=category).order_by("-entry_date")
you probably want something more like:
current_entries =
Entry.objects.filter(entry_cat__category_name=category).order_by("-entry_date")
(Here I'm guessing your Category model has a character-type field named
'category_name' that is what you really want to be matching -- you'll need
to fill in the actual field name from your Category model that you want to
match against.)

Re: _get_next_or_previous_ usage
You can find the definition of those methods at: /django/django/db/models/base.py:def _get_next_or_previous_by_FIELD(self, field, is_next, **kwargs): /django/django/db/models/base.py:def _get_next_or_previous_in_order(self, is_next): So, check on your django installation to see what they do. However, note that methods starting with an underscore mean you shouldn't be using them, they're for internal use. See the source and use at you own will. BTW - I don't know why those methods are for, and never used them nor see their code (just grep`ed to find where they're defined).

Semantically comments application is not intended for creating new
first-class data on your site, so the fact that you have no obvious
object to attach your comments to indicates that you're going to do
something wrong.
Just write a Testimonial model and create a view with form to edit it
(you may make use of generic views which reside in
`django.views.generic.create_update`).

Re: Sorting list of objets in Python/Django
You could also achieve that using the __cmp__ magic method[1]:
class a:
def __init__(self, name, number):
self.name = name
self.number = number
def __cmp__(self, other):
return cmp(self.name, other.name)
def __repr__(self):
return "a(%s, %s)" % (repr(self.name), self.number)
b = []
b.append( a('Smith', 1) )
b.append( a('Dave', 456) )
b.append( a('Guran', 9432) )
b.append( a('Asdf', 12) )
b.sort()
print b
# [a('Asdf', 12), a('Dave', 456), a('Guran', 9432), a('Smith', 1)]
The __cmp__ method does the magic, it's used when you call b.sort().
I added __repr__ just to see legible output...

Passing in a value from a url
Hi, I am currently trying to pass in a value from a url and the
perform a query based on that, i've tried this:
def category_view(request, category):
current_entries = Entry.objects.filter(entry_cat=category).order_by("-
entry_date")
return render_to_response('blog/base.html', locals())
but I get this:
Caught an exception while rendering: Truncated incorrect DOUBLE value:
'general'
Is this because the value isn't a string, and how can I get it
working, I know the value is being passed into the view correctly.
Thanks,
Andrew

Re: Django -- very very basic query !
I would suggest taking a couple of hours to do the tutorial, and it basically runs through most of what django can do. Since 1.0 is out, you just need to download, install and run through the tutorial. It runs on any platform. Have fun.

Comments
the Django docs state that "Django's comments are all "attached" to
some parent object"...
I'm building a very simple django powered website with auth,
flatpages, and comments currently installed. I want to use the
comments so people can post testimonials which can then be displayed
on the site. What would I attach to using this form statement as a
starting point:
{% render_comment_form for [object] %}
ie what should the object be?

However when I try the above I get: 'NoneType' object is > unsubscriptable There are two types of clean methods on forms. clean_FIELDNAME() is called on validation of each field. Note that the actual name of the method is clean_ plus the name of your field - in your case clean_logo. You must return the validated value if it passes. clean() is called on validation of the whole form. This is useful if you want to check dependencies between fields. You must return the full cleaned_data dictionary. The reason why you were getting a blank row is you didn't return anything, so there was nothing to enter into the database. -- DR. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I once discovered that you will get a blank page if a string like "forlì" is not first encoded to UTF-8 and then percent-encoded by the browser, but just percent-encoded from e.g. latin-1 directly... maybe that's the problem here, could happen with older browsers. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Admin field custom validation
Hi,
This is my code:
class LogoAdminForm(forms.ModelForm):
class Meta:
model = Logo
def clean(self):
from django.core.files.images import get_image_dimensions
logo = self.cleaned_data['logo']
w, h = get_image_dimensions(logo)
if w > 150 or h > 150:
raise forms.ValidationError(u'That logo is too big. Please
resize it so that it is 32x32 pixels or less, although 150x150 pixels
is optimal for display purposes.')
return logo
class LogoAdmin(admin.ModelAdmin):
exclude = ['height','width',]
form = LogoAdminForm
search_fields = ('name','logo','altText',)
list_display = ('name','logo',)
admin.site.register(Logo,LogoAdmin)
This works when editting a logo, but when I try to add a logo it
enters a fully blank row into the database.
Can anyone give me a hint as to why this is the case please ?
Thank you

You haven't explained where the problem is occurring. Is the correct data getting to your view function and then you aren't sending back the right information? If so, look at django.utils.http. I can't see how that would be resulting in a completely blank page, however. Also "a blank page" could be more accurate: is no data at all being sent back? Or is the user receiving an HTML page, but there's not visible data? Is Django crashing? Or is your view function completing, but not generating any data? You are saying that when a user does something, Django doesn't return something. But there are a lot of steps in the middle there. It sounds like you've done some debugging already, but it isn't clear to me, at least, where things are going wrong.
