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

Description

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?

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)

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).

  • keywords set to sprintsept14.
  • has_patch set to 1.

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.
