I found that DATE_INPUT_FORMATS used for JS I18N is not format I defined
in app/formats/*/formats.py file (FORMAT_MODULE_PATH = 'app.formats')
Django version is 1.2.4
I found that get_formats uses invalid order of formats - so format I
defined is being overwritten by Django's default ones.
That is serious bug as Django JS uses different formatting than server-
side code.
To prove that I changed file django/views/i18n.py to debug the issue:
{{{
def get_formats():
"""
Returns all formats strings required for i18n to work
"""
FORMAT_SETTINGS = (
'DATE_FORMAT', 'DATETIME_FORMAT', 'TIME_FORMAT',
'YEAR_MONTH_FORMAT', 'MONTH_DAY_FORMAT', 'SHORT_DATE_FORMAT',
'SHORT_DATETIME_FORMAT', 'FIRST_DAY_OF_WEEK', 'DECIMAL_SEPARATOR',
'THOUSAND_SEPARATOR', 'NUMBER_GROUPING',
'DATE_INPUT_FORMATS', 'TIME_INPUT_FORMATS',
'DATETIME_INPUT_FORMATS'
)
result = {}
modules = [settings] + get_format_modules(reverse=True) # DEBUG
log = '%r:\n' % modules # DEBUG
for module in modules:
for attr in FORMAT_SETTINGS:
try:
if attr == 'DATE_INPUT_FORMATS': # DEBUG
log += " %r from %r\n" % (getattr(module, attr,
None), module) #DEBUG
result[attr] = getattr(module, attr)
except AttributeError:
pass
log += "=> %r from %r" % (result.get('DATE_INPUT_FORMATS'), module) #
DEBUG
if result.get('DATE_INPUT_FORMATS') != ('%Y-%m-%d', '%m/%d/%Y',
'%m/%d/%y'): # DEBUG
logging.getLogger('coupon.localebug').error(log) # DEBUG
# remaining code is cut
}}}
That's the output I got:
{{{
[<django.conf.LazySettings object at 0x2359fd0>, <module
'app.formats.fr.formats' from '/XXX/app/formats/fr/formats.pyc'>, <module
'django.conf.locale.fr.formats' from '/XXX/pyenv/lib/python2.5/site-
packages/django/conf/locale/fr/formats.pyc'>]:
('%Y-%m-%d', '%m/%d/%Y', '%m/%d/%y', '%b %d %Y', '%b %d, %Y', '%d %b
%Y', '%d %b, %Y', '%B %d %Y', '%B %d, %Y', '%d %B %Y', '%d %B, %Y') from
<django.conf.LazySettings object at 0x2359fd0>
('%Y-%m-%d', '%m/%d/%Y', '%m/%d/%y') from <module
'app.formats.fr.formats' from '/XXX/app/formats/fr/formats.pyc'>
('%d/%m/%Y', '%d/%m/%y', '%d.%m.%Y', '%d.%m.%y', '%Y-%m-%d',
'%y-%m-%d') from <module 'django.conf.locale.fr.formats' from
'/XXX/pyenv/lib/python2.5/site-
packages/django/conf/locale/fr/formats.pyc'>
=> ('%d/%m/%Y', '%d/%m/%y', '%d.%m.%Y', '%d.%m.%y', '%Y-%m-%d',
'%y-%m-%d') from <module 'django.conf.locale.fr.formats' from
'/XXX/pyenv/lib/python2.5/site-
packages/django/conf/locale/fr/formats.pyc'>
}}}
That means that my format is used, but it is not the last in the order, so
it is being overwritten.
