This Week in Django is a weekly podcast about all things Django.
This week we do a DjangoCon retrospective, feature a special live interview with Pownce developers Leah Culver and Mike Malone, discuss a few source commits and some cool projects from the community.
Last weekend I had the unique privilege to attend and participate in DjangoCon, the first international Django based conference. It was a wonderful experience and I had the great opportunity to meet a lot of incredibly smart people. I was especially excited to be able to participate by Moderating two discussion panels and doing the This Week in Django show live. The whole thing was held at Google, which is just amazing, and they recorded all of the presentations and have made them available. I encourage you to enjoy the fun. note, if you want higher quality videos watch them on YouTube and select “watch in high quality”. I participated in the following:
A technical design discussion panel featuring core developers: Jacob Kaplan-Moss, Adrian Holovaty, Simon Willison, James Bennett, Malcolm Tredinnick. This one was a ton of fun and I only wish we had more time. I had a bunch of questions that I did not get the opportunity to ask, and others that were covered in prior keynotes so I thought it was best not to harp on them any longer.
A panel discussion on Schema Evolution and three popular approaches to this problem for Django. Featured project leads Simon Willison (dmigrations), Russ Keith-Magee (django-evolution), Andrew Godwin (South). This panel had some spirited discussion on schema evolution and their different approaches. It seems that there are enough similarities that we will hopefully see some collaboration among the projects.
Michael Trier & Brian Rosner do a live presentation of the This Week in Django podcast. We were a bit nervous about this one since in our regular weekly podcast we have an opportunity to stop and start or do certain item over again. With the exception of a couple of minor mistakes it turned out great and was tons of fun. I was quite surprised by the number of questions that were asked. The only bummer about this one right now is that it cuts off the intro and the outro, but we’re trying to get Google to restore that.

#geodjango on freenode.(8136) – Excellent addition by Eric Forenzano and Russell Keith-Magee that allows you to add join models with extra attributes.
(8162) – It uses a token and prompts user for new password, plus also adds base36 encoding and decoding.(8191) – Removes:
extensions to django_extensions. This will happen in one week.Use decorator_from_middleware to create a decorator that can be used in your views, which wraps up a middleware class.
from django.utils.decorators import decorator_from_middleware
from django.middleware.middlewaremodule import MiddlewareClass
decoratorfunc = decorator_from_middleware(MiddlewareClass)

Satchmo is a Django based E-Commerce solution.
SCRIPT_NAME and PATH_INFO (8015) – Basically, URL resolving will only use the PATH_INFO and the SCRIPT_NAME will be prepended by reverse() automatically. Allows for more portable development and installation. Also exposes SCRIPT_NAME in the HttpRequest instance.(8050): – Since it’s not required, by default, set the default properly in the constructor.(8088) – Implemented by using pagination.

(7949) – According to Malcolm Tredinnick, it smells bad and has no friends.(7971)
** django.newforms is now django.forms. Updated your code.(7985) – This one has bit us on the Django Logger.This tip comes to us via Ben Jao Ming in his post Django auto-translation of field values.
If you need to translate content in a field then gettext is not going to help you out. Since you can create your own custom fields it’s easy to wrap a CharField with the translation behavior:
from django.db import models
from django.utils.translation import gettext_lazy as _
class AutoTranslateField(models.CharField):
__metaclass__ = models.SubfieldBase
def to_python(self, value):
return str(_(value))
Just add whatever translations you know of to the locale file and run compilemessages.

Mike Axiak offers the following tip for getting started with contributing to Django source code.
1. Find a closed ticket that interests you. 2. Take a look at a closed ticket, but not the patch. 3. Check out the revision prior to the one that closed the ticket. 4. Write a patch for Django with your own implementation. 5. Compare your patch with the committed patch and try to learn from the differences.
Once you’re comfortable do it for real.
Apologies to all but there will be no This Week in Django podcast this week. Enjoy the week off and we look forward to seeing you all next week on TWiD Live.

Malcolm Tredinnick is back!!!
(7739) – Previously if the date field was nullable no results were returned. (7740) – Previously, if we were querying across a nullable join and then a non-nullable one, the second join would not be a LEFT OUTER join, which would exclude certain valid results from the result set. (7741), (7773), and (7760) through (7766) – Lots of miscellaneous QuerySet changes(7784) – When model inheritance is used, the parent objects should be deleted as part of the delete() call on the child. (7791)code_swarm – An experiment in organic software visualization.Ever need to reorder the fields on your Model Form?
class TranslationForm(BookForm):
translator = forms.CharField(max_length=40)
def __init__(self, *args, **kwargs):
super(TranslationForm, self).__init__(*args, **kwargs)
self.fields.keyOrder = ['title', 'author', 'translator', 'publisher', 'copyright']

Charlie O’Keefe say, “I’ve gotten into designing restful URL schemes, basically organizing a web app around resources. Learning Django I was frustrated to find that nothing seems to be done this way. Is there any tool that can help with that?”

group_required Decorator – Matt Dennebaum offers a nice addition to your Django projects that adds the ability to check for authorization of a user against the specified group.This tip comes from Alexander Solovyov in his blog post Render To Improved.
Sometimes you want to return a RequestContext from a view. One way to do that is to specify the response code using a decorator.
@render_to('mytemplate.html')
def myview(request):
return ({'id': 1, 'name':'empty'})
# example with override
@render_to('mytemplate.html')
def myview(request):
return ({'name':'empty'}, 'override.html')
# python 2.3 example with override
def myview(request):
return ({'name':'empty'}, 'override.html')
myview = render_to(myview, 'mytemplate.html')
You can also return a tuple where the second item is a string that overrides the default template specified in render_to.
Backwards Incompatible Changes Information
What’s the difference between Abstract Base Classes and Multi-Table Inheritance?
Abstract Base Classes are where you provide a base class, like Person, and then a derived class like Employee. Django will create a single database table for the Person model that contains the combined fields from both the base and derived classes.
Multi-Table Inheritance also has the base and derived class but at the database level you end up with two tables: one for the base class and one for the derived class, with a one-to-one field added in to connect the two.
Again, we highly recommend the excellent post by Kevin Fricovsky that we mentioned in Community Catchup. Plus, as always, the excellent Django documentation.
Is there a way to pass the filter arguments as string to the QuerySet?
QuerySet parameters are standard Python keyword arguments, and can use standard keyword argument expansion.
Post.objects.filter(datetime__year=2008)
Post.objects.filter(**{'datetime__year': 2008})

EuroPython Django Sprint – We are holding an official Django sprint, July 10th until saturday July 12th, during the EuroPython conference. Join us in the push to 1.0.

(7601) – Update doesn’t reliably support limit and offset.--exclude option to dumpdata (7615) – This makes it possible to exclude a particular application from the output.(7643) – This makes it easier to control behavior through the database backend.(7653) – It now displays the entire traceback.(7627)
(7630)
(7606)If you have a template tag that you want to automatically load into context for all of your templates, you can take the same approach Django does with the built-in template tags.
This must be done early on in the load process, so in your __init__.py for the app or project, just do:
from django.template import add_to_builtins
add_to_builtins('template_utils.templatetags.generic_content')
