Yes, it's a single query.
Take a look at django-debug-toolbar. It can display all SQL queries
that was executed during request/response so you'll always be sure
what's going on.

It is very likely that your urls.py is wrong. Re-check if admin urls
are included exactly as in documentation example: "(r'^admin/', include
(admin.site.urls))", without any wildcards.

You should override change_form.html template and save it as
/your_project/templates/admin/your_app/change_form.html
or
/your_project/templates/admin/your_app/your_model/change_form.html

If you want to be able to sort by some python method you have to fetch
ALL data from all tables that are used in this method. It is indeed a
bad practice and so it is not encouraged in django.
The best you can do is to put your code to model's manager as a
method. Model managers are often used fo
Maybe I wrote a reply without undersanding what you need.
You have 2 separate issues:
1. Want to sort and filter by calculated field
2. Want to create calculated field that is calculated in python
Am I correct?
1) can be acheived using ".extra" method or aggregations
http://docs.djangoproject
I think if your methods are really complex then the best you can do is
to denormalise your DB.
Make your calculated fields real fields in a table and update them in
model's save method or using signals.
Another way is to make them calculated by DB using triggers or DB
views but I would prefer den
Performance monitoring doesn't have to be related to django itself.
There are external projects that cant do performance monitoring (CPU,
i/o, memory usage over time). You may give munin (http://
munin.projects.linpro.no/) a chance.

Hi Rogério,
You can give http://bitbucket.org/kmike/django-qsstats-magic/src a
try.
It currently have efficient aggregate lookups (1 query for the whole
time series) only for mysql but it'll be great if someone contribute
efficient lookups for other databases :)

Hi Yves,
In django 1.3 there is also a TemplateResponse (
http://docs.djangoproject.com/en/dev/ref/template-response/ ) that can
perform as render_to_response replacement, doesn't require class based
views and enables developer to change the template context (as well as
the template to be rendered

Hi Igor,
If you use django <= 1.2 the you can replace 'render_to_response' with
'direct_to_template'. They do almost the same but 'direct_to_template'
uses RequestContext by default:
from django.views.generic.simple import direct_to_template
def my_view(request):
# ...
return direct_to_t
production = Production.objects.all()
for product in production:
try:
product.image = product.image_set.get (somefield = somevalue)
except Image.DoesNotExist:
pass
{% for product in production %}
{{ product.title }}
{% endfor %}
or even better implement the 'get_i
Hi Rahul,
This can be solved using custom javascript. Override ModelAdmin's
changelist template (
http://docs.djangoproject.com/en/1.2/ref/contrib/admin/#overriding-admin-templates
) in order to insert the necessary javascript code.

It doesn't work that way. ORM translates you queries to SQL and the DB
is responsible for filtering. It is not possible to translate
arbitrary python function to SQL or pass it to DB engine. So you have
to formulate you query using .filter syntax or raw SQL.
Another possibility is to denormalize d

Why doesn't setattr work? Just make sure you're setting the proper
option because apps often cache options at e.g. their 'config.py' file
in order to provide default values:
# captha_app/config.py
from django.conf import settings
CAPTCHA = getattr(settings, 'CAPTCHA', True)
So you'll have to chan
