Hello,
OK, I found out the issues, and came up with a solution, if any one cares :)
Requirements:
- A get_request patch
- A REQUEST object that will have the necessary information to locaize from
(language code, etc ...)
How I do it:
- Copy Python lib's locale.py to your product
- import Globals
- Force "locale emulation", I do it by raising an ImportError when importing
_locale
- Hardcode the dicts that contain the usual localconv() output for the locales
you're interested in
- Edit the localeconv() emulation to get the request, and from there get the
localization information somehow (I base it on HTTP_ACCEPT_LANGUAGE for
example), and then return the dict information.
- import locale in __init__.py
Works great for me, and was pretty straightforward.
Notes:
- You might be able to do this through monkey patching ... I copy the module
because I'm using 2.5's locale module with 2.4 ... To get currency() support.
- You might want to put Module security declarations in there somewhere.
- Nice benefit that you can easily change the number/currency parameters to
your liking, if needed.
Some code (Sorry can't just share/open source it all, due to my employer's
policies):
<...>
# Zope imports
import Globals
from Products.CMFCore.utils import getToolByName
<...>
try:
# from _locale import *
raise ImportError
except ImportError:
# Locale emulation
<...>
def localeconv():
""" localeconv() -> dict.
Returns numeric and monetary locale-specific parameters.
"""
request = Globals.get_request()
portal_localizer = getToolByName(request.get('PUBLISHED'),
'portal_localizer')
locale_suffix = portal_localizer.getProperty('locale_suffix')
return LOCALECONV[request.get('HTTP_ACCEPT_LANGUAGE', 'en') +
locale_suffix]
<...>
LOCALECONV = {'en_CA':
{'mon_decimal_point': '.',
'int_frac_digits': 2,
'p_sep_by_space': 0,
'frac_digits': 2,
'thousands_sep': ',',
'n_sign_posn': 1,
'decimal_point': '.',
'int_curr_symbol': 'CAD ',
'n_cs_precedes': 1,
'p_sign_posn': 1,
'mon_thousands_sep': ',',
'negative_sign': '-',
'currency_symbol': '$',
'n_sep_by_space': 0,
'mon_grouping': [3, 3, 0],
'p_cs_precedes': 1,
'positive_sign': '',
'grouping': [3, 3, 0]},
'fr_CA':
{'mon_decimal_point': ',',
'int_frac_digits': 2,
'p_sep_by_space': 1,
'frac_digits': 2,
'thousands_sep': ' ',
'n_sign_posn': 0,
'decimal_point': ',',
'int_curr_symbol': 'CAD ',
'n_cs_precedes': 0,
'p_sign_posn': 1,
'mon_thousands_sep': ' ',
'negative_sign': '-',
'currency_symbol': '$',
'n_sep_by_space': 1,
'mon_grouping': [3, 3, 0],
'p_cs_precedes': 0,
'positive_sign': '',
'grouping': []}
}
</...>
Hope this comes in handy to someone!
J.F.

Subject: [Zope] Zope, setlocale(), requests and traversal
Hello,
I know there is a locale setting in etc/zope.conf, and I make use of it.
The problem now, is that I have a multilingual site that I would like to have
support multiple locales, per request: One request could be for the french
site and content, using the fr_CA locale in my case, but another could be for
english, and en_CA ... Localization is done through a traversal hook.
So right now I call setlocale() on a per request basis, and it works fine in
development.
So I'm wondering:
- I see the docs mention setlocale might not be threadsafe, since Zope is
threaded, anyone know the implications?
- If I call setlocale() during traversal, could that setting affect other
threads/requests?
- If the above 2 are indeed problems, is there some nice way to do set
per-request locales, short of completely implementing a custom way of doing it?
Thanks!
