OK, thanks
Always learning.
What I miss from my other programming is MSDN like style of help
pages. I tend more and more to use the django pdf documentation
because I can't get used to the web interface for this.

Both patterns will produce same query. You can also use
django-debug-toolbar, which gives ur debugsqlshell tool. So you can execute
code from the commandline and can see what the query will be.
Django also has a code pattern for your case - for getting the first
element, you can just use latest
OK, thanks for sharing this

I am a Django newbie and also interested in this question.

I see that the query 'Publisher.objects.order_by('name')[0:2]' maps
to:
SELECT id, name, address, city, state_province, country, website
FROM books_publisher
ORDER
Hello!
I want to get just the top element of one queryset. SO I have
something as
qs=MyModel.objects.filter(...).order_by(..)
and then use qs[0] and check some value
I wonder now if i did the right thing or it is better to use .extra on
queryset.
Is the queryset object allocated for all objects,
thank you so much.

It's not usually called overloading in Python, but yes. Classes can define
a `__getitem__` method
thank you.
then a basic python question.
how does queryset implement it?
does python also allow operator (e.g. []) overloading?

Actually, there doesn't need to be an insert between the calls if you
don't use .order_by(). Technic
so it means when i call user[1] after user[0], it is possible that i
will get same record if someone else insert a new record into database
between 2 calls.

Yes. That is exactly what happens:
In [7]: qs[0]
Out[7]:
In [9]: print connection.queries
[{'time': '0.011', 'sql': 'SELECT ... FROM "organisaatio_osa" LIMIT
1'}]
In [10]: qs[0]
Out[10]:
do you mean that queryset will query database every time i call
user[0]?

The reason is that Django does not do "instance caching".
user = User.objects.filter(pk="")
user is a QuerySet
every time i call user[0], i returns a different reference.
maybe it should be a python question.
i want to know i QuerySet does that.

query = request.GET.get('q', '')
if query:

Hi, I am new to Django (and python), and I have a question regarding
database query stuff
Basic info - I have a category model and an article model, and each
article is linked to a category through a foreign key
If i have the following code
---
category = Category.objects.all()[0]
return Http
