Well, the "Triage Stage" is currently set at "Design decision needed"
which means that it's waiting for a core dev to review the ticket and
either accept or reject it.

I don't - and I just posted a comment to the ticket explaining why. If
you (or anyone) wants case-insensitive sorting, just create your own
custom filter that does just that. You could even copy the built-in
filter to your own project/app and use it with a one or two line
change.

The collation for other languages than English is not that simple.

e.g. the German Umlaut "ä" is often seen equivalent to "ae" when
ordering lists. Thus a list like [u'baf', u'bäx', u'baz'] would be
sorted [u'bäx', u'baf', u'baz']. There are even some collations that
just treat 'ä' as an 'a' and some that order 'a' < 'ä'.

In short: The ordering should depend on the locale being used and not on
some .lower() magic.


Ordering strings depending on the language, hat's what locale.strcoll is
good for:

And don't just use locale.strxfrm as suggested in the user comments
because it is buggy in python 2.5 and doesn't work with unicode strings:

Maybe django should provide a <insert-good-name-here> function inside
the django.utils module and provide sorting based on the current locale
and/or language of the current request. I guess it's an often made
mistake to just rely on the string ordering while in reality wanting
ordering based on the locale.

Great post Michael, i did a python module to do that, and i called the
function isorted (but its principle can be used in a django filter too).

Here is the code:

Please, if you have any comments on how to improve it, or if i have to
do something to add it to django (im a newbie in django core
development) just say it and im sure to do my best.

Also sent this to Marinho to see if we could put in django-plus.

Thanks a lot and i really hope that we can find a way to improve this in
django.
