I want to use that to answer does Django work efficiently and does it scale? When you get asked "My Database has N-Gazillion rows and app needs x concurrent users", showing some sites which use Django and push 500,000 pageviews per day would be good. I tried to glean this information from Djangosites and corelate to Alexa, but maybe I am missing some other big ones.

Re: Getting started with Django: New Udemy Class, free for a limited time
I was hoping to get about 100 people in a month, but we already have 289 people signed up in a week. :). I wasn't expecting this. (You can verify this at Udemy.) Because I am still adding the content, I am keeping the price to $9 for the whole of February, and would raise once I am done with adding the tutorials. You can join here: http://www.udemy.com/getting-started-with-django2/ Whats added already. 1. 4 part screencast for the four part Django tutorial. 2. Screencasts on using pip, pep8.py, pyflakes, ipython. 3. PDF versions of Django design patterns and Djen of Django book. 4. Various other tutorials. 5. Code samples of all code written in the screencasts and the tutorials.

Editing the RSS in the Django community feeds
Hello, The Django community RSS feeds has a form to add new RSS: https://www.djangoproject.com/community/add/blogs/ We have our RSS added in this from way back. However sometime we write about non-django stuff, which is not relevant in this feed. I would like to update this to our Django only feed: http://agiliq.com/blog/rss/latest/django/ Can someone with access do this?

Hi Russel, Thanks for your help. Looks like I was using this via feedburner, so I just updated it at the feedburner level.

Re: Editing the RSS in the Django community feeds
Hi Guys, Updating feedburner actually pulled in a lot of old entries in the community feed. I am not sure why. My apologies for pushing this to the feed. Hopefully the feed will pick up only the new entries from now on.

Using .extra after using .annotate is not working
I am trying to get a field in a queryset which depends on the result
of the annotations. I tried using extra on an annotated queryset,
which doesn't seem to work.
Lets say my models looks like this:
class Foo(models.Model):
name = models.CharField(...)
class FooData(models.Model):
foo = models.ForeignKey(Foo)
sales = models.PositiveIntegerField()
items_sold = models.PositiveIntegerField()
I have a queryset of Foo objects
some_foos = Foo.objects.filter()
I have annotated it to get the sum on FooData.
some_foos.object.annotate(
total_sales=Sum("foodata__sales"),
total_items_sold=Sum("foodata__items_sold")
)
Now I want to get the average price for which I am trying to
use .extra. They don't seem to work. (I have looked the generated sql
queries).
#Wont work, fields not defined yet.
some_foos.object.annotate(
total_sales=Sum("foodata__sales"),
total_items_sold=Sum("foodata__items_sold")
).extra(select={'price_avg': "total_sales/total_items_sold"})
#Wont work, this adds an extra clause in group by
price_avg = "SUM(appname_foodata.sales)/
SUM(appname_foodata.items_sold)"
some_foos.object.annotate(
total_sales=Sum("foodata__sales"),
total_items_sold=Sum("foodata__items_sold")
)
