databrowse calendars do not translate the month back to english resulting in an error

[lawgon <lawgon@…>]

When using databrowse in english, on selection of a year, the months are given. The url for clicking on a month would be ~/1998/feb/. This works. In finnish, on clicking the equivalent of february, the url becomes ~/1998/hel/ where 'hel' are the first three letters of the finnish equivalent of february. This obviously doesnt work.

I assume this is a generic i18n issue with databrowse?

[lawgon <lawgon@…>]

same problem in polish - so it must be i18n generic issue

Same in Czech language.

I looked into Django code and found, that calendar generate URLs with
month presented as 3-letters text. And that is propably the reason of
404 page -- in my language I get ugly URLs like:

​http://127.0.0.1:8000/databrowse/news/new/calendars/created/2007/b%C5%99e/
​http://127.0.0.1:8000/databrowse/news/new/calendars/created/2007/z%C3%A1%C5%99/

It is not so common approach to represent month as 3-letter shortcuts in
my country. In this situation will be better to represent month as
number, ie:

​http://127.0.0.1:8000/databrowse/news/new/calendars/created/2007/03/
​http://127.0.0.1:8000/databrowse/news/new/calendars/created/2007/09/

In django/views/generic/date_based.py I found, that archive_month
function have parameter month_format, but calendar_view (in
django/contrib/databrowse.plugins/calendar.py) leave it to default value
(%b).

Is it possible change the code to generate months in URLs as numbers,
instead of 3-letter texts please?

I try to solve it, but I am stuck, sorry.

What I found: I think, that problem is in strptime function (for example in django/views/generic/date_based.py line 119).

First, it is necessary to set correct locale. Next, if strptime gets date string as unicode, it throw exception UnicodeDecodeError. But, if I put there same string, but not as unicode it is successfull:

import locale
locale.setlocale(locale.LC_TIME, 'cs_CZ.UTF-8')
from time import strptime
strptime(u'2007kvě', '%Y%b') # this throw UnicodeDecodeError exception
strptime('2007kvě', '%Y%b') # this is OK (see, date string isn't unicode, but it contain unicode character)

[Fredrik Lundh <fredrik@…>]

Should the URI really used localized names? Wouldn't numbers or english names be more robust?

(the Unicode issues for CZ is different from the original case for FI, but a non-localized fix would solve both, I think).

I'm submitting a patch that fixes this by using numeric months in the URLs, as suggested by michal & fredrik. The patch also fixes a bug in the heading displayed by the calendar_month.html template.

New, refreshed version of the patch

[Nick Efford]

I've updated the patch to be against a more recent trunk (post-nfa merge).

[Adam Nelson]

Patch needs to be updated to latest trunk ... again.

[Dario Ocles]

patch updated to the last trunk

[Dario Ocles]

I updated to the latest trunk. I just aplied the same changes and the last patch. This is my first contribution so sorry if I make some mistake.
