Re: GROUP BY and ORDER BY using the ORM
Thanks Euan, some great info there.
I'll have a dig through the docs for F objects, I wasn't even aware of
them so thanks for point me in that direction!

Re: GROUP BY and ORDER BY using the ORM
You're right I sniped the date_time field when pasting in the model
after leaving out some extranous detail. Doh!
Ordering by date_time mean't I had duplicates despite grouping by
site. Like you say printing out the query may actually help me
understand what is going on under the hood.
After posting the message, I did a bit more reading I actually used
annotate(last_date=MAX('date_time')) which seems to work reasonably
well and give me the sort of result I was looking for. Again I'll
print the sql for this and see whats going on.
Extending the use case a bit further however what I'd really like to
do is determine how many days have passed since 'last date' and filter
the objects further. It sort of seems as though I'm getting to the
edge of what the ORM is capable of.
>From doing a quick bit of reading it either seems like I'll have to
use the extra() clause or perhaps look at using a property bound to a
method however at this point you're outside the scope of the ORM.
Any ideas on how I can best acheive this?
I'm trying to stay away from using a foreach and looping over a
potentially large number of records and doing this filtering at the DB/
ORM level.
Thanks in advance.

GROUP BY and ORDER BY using the ORM
Hi all
Just coming back to Django after a long time away, and struggling to
get my head around what should be a trivial concept using the ORM.
Essentially I want to do acheive the following SQL:
SELECT * FROM publisher_history
INNER JOIN publisher_publisher ON publisher_publisher.id =
publisher_history.publisher_id
GROUP BY publisher_id ORDER BY date_time DESC;
My models look like this:
class Publisher(models.Model):
name = models.CharField(max_length=100, blank=False)
class History(models.Model):
publisher = models.ForeignKey(Publisher, blank=False)
I've been trying to use object values, but I'm getting duplicate
publishers. Code looks like this:
results = History.objects.values('publisher').distinct()
If I run:
results = History.objects.values('publisher').distinct().order_by()
I don't get duplicates but I don't get the results returned in the
order I expect either.
Any help would be greatly appreciated, I've stared at this for a while
now.

Re: Filtering ManyToManyField
Anyone?
I'm really struggling with this.
As stated in my first post running the code creates a recursive loop.
Had a bit of a hack around with things, but can't figure anything
obvious out.

Filtering ManyToManyField
I was wondering if anyone could help me. I currently have a Product model which has a many to many association linked back to itself for related items. When returning the related items, I want to filter out any which are not currently flagged as active. Initially I thought about doing something like this: def _get_related_items(self): self.related_items.exclude(active=0) related_items = property(_get_related_items) However I've managed to create a recursive query. Could anyone clarify what I need to do be doing to acheive the desired filtering? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Forms across multiple pages?
Can't seem to find anything of relevance in the docs, so wondering if someone could help me. Basically I want to put an email signup form in the footer of my site, which I can display errors/success message in place. Other than using Ajax to post this info in the background is there a way in Django to actually have a form on a page which has an action to another page and return error messages/success message back to the previous one i.e hooking in to global error variables or similar?

Re: Standalone script + get_absolute_url with urlresolvers

Re: Standalone script + get_absolute_url with urlresolvers
Yeah. I did think that.
As far as I'm aware there aren't any errors in any of the views,
however the views.py file for scripts it is an empty file. I'm
guessing this is the problem in itself.
Is it syntactically correct to have a views.py which is empty but
exists? I'm not really sure of the process Django will use to validate
the view.
I've also pasted the stack trace to Dpaste: http://dpaste.com/64942/

Standalone script + get_absolute_url with urlresolvers
I was wondering whether anyone can help me with a problem I'm having.
I'm running a standalone script outside of the web server to do some
maintainence tasks.
In particular I need to return the absolute url from one of my models,
however when I call the get_absolute_url() method, I'm getting a
ViewDoesNotExist exception raised. A view exists however upon further
investigation I've found that this line of code is causing me some
real problems:
return urlresolvers.reverse('satchmo_product', kwargs={'product_slug':
self.slug})
Basically it appears that Django is concatenating the view path or
similar, so instead of either searching in:
satchmo.shop.views or satchmo.scripts.views
Its actually searching in satcho.shop.views.satchmo.scripts.views
Anyone got any idea how I could overide Django to tell it where to
search for the view or similar?

Access urls in template tags?
Basically I'm looking to expand a sub navigation dependent upon
whether the category belongs to the selected hierachy.
Basically I was thinking of doing something along the lines:
url = 'parent/child'
url_bits = url.split('/')
if cat.slug == url[1]:
#build parent nav - don't recurse
else:
#build parent/child nav - hence recurse
The logic should be fairly straightforward, however what I'm stumped
by is how I would access the url within a template tag given I won't
already have a request object.
Is there a simple way to do this within the template tag or would I
need to create a context processor and would this be available within
the templatetag or only within the template itself?

Re: form_for_instance + user profile
Well I thought I had this working but it turns out it was previous
form I had set up manually.
At the moment I'm getting no form returned at all, from reading the
documentation I'm struggling to see what I'm doing wrong.
My UserProfile model is sat in eshop.shop.models, I'm referencing this
in settings.py like so:
#Use the shop profile model
AUTH_PROFILE_MODULE = 'shop.UserProfile'
Model looks like this:
class UserProfile(models.Model):
title = models.CharField(maxlength=10)
user = models.ForeignKey(User, unique=True)
View looks like this:
user = get_object_or_404(User, id=12)
user_profile = user.get_profile()
UserForm = form_for_instance(user_profile)
if request.method == 'POST':
form = UserForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/url/on_success/')
else:
form = UserForm()
return render_to_response(template_name, {'form': form},
context_instance=RequestContext(request))
Can anyone spot the glaringly obvious mistake I'm struggling to see??

form_for_instance + user profile
I've had a read through the docs and have created a UserProfile object
with a ForeignKey to Djangos User object.
What I want to be able to do is load the UserProfile so this can then
be edits.
I tried this last night (admittedly not very hard) and didn't seem to
have any joy.
Basic example:
user = User.objects.get(id=1)
user_profile = user.get_profile()
user_form = form_for_instance(user_profile, fields=('a field I want to
filter'))
Should this work or should I be loading the user profile like so:
user = User.objects.get(id=1)
user_profile = UserProfile(user)

Re: Temporary access to link in django
I think you may be complicating things unnecesarily by not creating a user. Why not look at creating a temporary user group, and maybe adding an additional check at login if this user is a temporary user, they cannot login 1 month after the date created of the user?

Re: first naive question for a new fresh Django user
To be honest I'm not really sure the use of Ajax in printing a piece
of text from a field is that necessary. This could easily be acheived
using good old javascript.

Re: Email as username in django auth framework
I'm using this snippet which works fine. In order to get this working, I generate a random string as the username on creation and created a unique index on the email address field. I guess it goes a little against the grain given you're patching the db however I feel email address fields should be unique to ensure you don't have multiple users registered with the same address.

Re: Newbie (Before I get started)
I've been working in Django for all of about 4 weeks and I'm absolutely loving it. Within that time I've written my first project, something which I probably would never have acheived in another language (I'd still be stuck reading the book!) To give you a little on my background, I've programmed PHP for around 8 years, having previously worked with ASP, Perl and looked at both .NET and Rails in passing. Recently I've been using Python for some backend scripting and came across Django so I thought I'd do a little more reading around >From what I saw in that bit of reading I was pretty much blown away by the ethos of the project and I've been hooked ever since. Yep, there are less resources available for Django at the moment however the documentation is more than sufficient (it just take a little reading), there is a book soon to be published and available at: http://www.djangobook.com On top of this the group is both very helpful and very active and active with the people who are actually developing the framework which surely counts for something! The admin system is extendable to meet your requirements, I see the admin as more of a bonus than a hinderance. Ruby more forgiving than Python, can't really comment as I'm not overly familiar with Ruby's syntax.

Hierarchical menus
I was wondering whether anyone can help me, I'm absolutely stumped
where to start creating a hierarchical menu in Django. I've scoured
Google and don't seem to be able to find anything to get me started.
Basically I'm looking to create a simple list based menu like so:
> Home
> Category 1
> Range 1
> Range 2
> Category 2
> Category 3
To explain I currently have my models like so:
class Category(models.Model):
id = models.AutoField('id', primary_key=True)
name = models.CharField(maxlength=50)
class Range(models.Model):
id = models.AutoField('id', primary_key=True)
category = models.ForeignKey(Category)
name = models.CharField(maxlength=50)
Initially I'd thought about using the select_related syntax along
these lines:
Range.objects.all().select_related()
However I'm not sure that is going give me the granularity I won't be
able to determine the depth of the navigation or whether this is the
parent of the range selected.
Any help would be greatly appreciated!

Re: index page
It really depends on how complicated you want to make it. However using generic views would easily suffice, just set up a dictionary of the objects you need to pass in.

localflavor - UKPostcodeField
Hi I came across localflavors and would like to use the UKPostcodeField for post code validation. However when I try to import this I'm getting ViewDoesNotExist errors. Within my forms.py I'm importing like so: from django.contrib.localflavor.uk.forms import UKPostcodeField I'm then referencing this within the class like so: models.UKPostcodeField() >From here I've also checking within the Django installation on my python path to ensure that this exists.

Re: Attribute Error
Guys I spent quite a while yesterday reading through the newforms section of the docs, and thought I'd taken everything in. As a python novice, I wrote a test script and couldn't replicate the error, so was beginning to wonder whether I was cracking up! After reading Malcolm's (comprehensive) response, it does make alot more sense and I feel to have a better understanding of how the newforms library hinges together. I've got to say as someone new to django I'm really impressed at the level of support you guys have got going on.

Attribute Error
Hi I was wondering whether anyone can help me out.
I'm currently creating a form to register users, what I'm finding is
that when I then attempt to save the user within the Register:save
method I'm getting an attribute error when trying to access the title
attribute. I've tried referencing both title, and self.title to no
avail.
Can anyone advise me on where I'm going wrong with this?
class Register(forms.Form):
def __init__(self, data=None, request=None, *args, **kwargs):
if request is None:
raise TypeError("Keyword argument 'request' must be
supplied")
super(Register, self).__init__(data, *args, **kwargs)
self.request = request
#personal information
title = forms.ChoiceField(choices=titlechoice)
def save(self):
#set up the objects we are going to populate
user = User
user.title = self.title

Re: django-cart integration?
Importing other bits of code is still fairly new to me, I only started looking at django last week. I basically took the files out of subversion and created a dir structure like so: /eshop/shop /eshop/cart <- django cart installed here /eshop/talks <- additional django cart files Within my settings.py my installed apps looks like this: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', 'django.contrib.flatpages', 'django.contrib.sitemaps', 'eshop.shop', 'eshop.cart', 'eshop.talks', ) I've snipped the contents to keep it a readable length. All imports happen at the top of the page so hopefully this should give you an idea of whats going on. Models follow: eshop/shop/models.py from django.db import models from django.contrib.sitemaps import Sitemap import datetime #more model logic snipped contents eshop/cart/models.py from eshop.talks.models import Talk PRICE=12 # All units have a price of $12 for now. class Item: #snipped contents eshop/talks/models.py from django.contrib.sites.models import Site from django.db import models from django.conf import settings class Talk(models.Model): #snipped contents On Aug 16, 5:02 pm, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > I've got it set up, but it's not plug and play... it's tied fairly > closely to a model you don't have. > It's trying to import Teacher from that model.

Re: Site Map template required?
Malcolm
Thanks for your comments, indeed changing to use the sitemap view,
then returns a template does not exist error.
If I create a sitemap.xml file in my templates directory I then bypass
this. What I'm struggling with is that the documentation suggests that
the feed is automatically generated.
Is it then down to me to mark up a template and output the objects and
if so whats the naming of the object thats passed? This is something
that seems to have been skipped totally in the docs.
Regards
Mike

Generic View Pagination
>From reading the documentation on generic views, I don't seem to be
making much head way. Basically I'm looking to create a paginated page
displaying all products within a specific category.
Within my urls.py I call the category view within my app:
(r'^category/(?P\d+)/$', 'eshop.shop.views.category'),
My category view then looks like this:
from django.views.generic.list_detail import object_list
from eshop.shop.models import Category, Product
def category(request, category_id):
category = Category.objects.filter(id=category_id)
products = Product.objects.filter(category=category_id)
category_count = category.count()
product_count = products.count()
return object_list(request, queryset=products,
template_object_name='products', paginate_by=1,
template_name='category.html', extra_context={'category':category,
'category_count':category_count, 'product_count':product_count,
'category_id':category_id})
Within the template when I conditionally check for products or
categories nothing is executed, despite returning a product count of
4, and a category count of 1.
Am I missing something glaringly obvious, its driving me mad!

SlugField not prepopulating?
Hi
I was wondering whether anyone could help me, I just starting out with
Django and am attempting to write a simple web app. Ideally I'd like
to use a slug field populated based on the name of my product.
However the slug field is not being populated, my model looks like
this:
class Product(models.Model):
name = models.CharField(maxlength=255)
category = models.ForeignKey(Category)
slug =
models.SlugField(prepopulate_from=("name",),unique=True,editable=False)
description = models.TextField()
size = models.CharField(maxlength=50)
price = models.FloatField(max_digits=5, decimal_places=2)
delivery = models.ForeignKey(Delivery)
in_stock = models.BooleanField()
display = models.BooleanField()
pub_date = models.DateTimeField(editable=False)
def __str__(self):
return self.name
def save(self):
if not self.id:
self.pub_date = datetime.datetime.now()
super(Product, self).save()
Any help would be greatly appreciated
