django translation with format() does not work

Question

django translation does not happen for a field using choices..

models.py:

 class Reservation(models.Model):
  class Period:
    MORNING = 'morning'
    EVENING = 'evening'

    @classmethod
    def choices(cls):
        return (                
            (cls.MORNING, _('Morning')),
            (cls.EVENING, '{} until {:%I %p}'.format(_('Evening'), datetime.time(16)),
        )       

 period = models.CharField(max_length=10, choices=Period.choices(),)

I am using {{ reservation.get_period_display }} in the template to display the field in few languages.Translation is fine for first choice cls.MORNING: الصباح. For the second choice (cls.EVENING), translation does not happen:"Evening until 04 PM"

Can anyone suggest me what is wrong with the format specifier, and why translation/localization is not working in this case.

N.B: The translation and i18n is setup properly and other places in my project is correctly showing translated values.

What is `_`? Is it `ugettext_lazy` or the non-lazy version? – RemcoGerlich Oct 24 '16 at 11:13 — RemcoGerlich, Oct 24 '16 at 11:13
_ is ugettext_lazy version – Grizzled Squirrel Oct 24 '16 at 11:14 — Grizzled Squirrel, Oct 24 '16 at 11:14

You should wrap second line string in ugettex_lazy not just Evening

(cls.EVENING, _('{} until {:%I %p}').format(datetime.time(16)),

Read more Strings won't be translated in Django using format function available in Python 2.7

Also be sure to add #, python-brace-format. Like in this example

#: accounts/forms.py:691
#, python-brace-format
msgid "La validation de votre carte a échoué: ({0}) {1}"
msgstr ""

"{} until {:%I %p}" appears in django.po file. translation does not work irrespective of whatever string you provide for this. – Grizzled Squirrel Oct 24 '16 at 11:41

@GrizzledSquirrel see updated answer. I fixed first line too using `_().format` – Sardorbek Imomaliev Oct 24 '16 at 11:53
added po file: #, python-brace-format msgid "until {}" msgstr "حتى {}" still not getting translation.., – Grizzled Squirrel Oct 24 '16 at 12:52
@GrizzledSquirrel try with indexes. – Sardorbek Imomaliev Oct 24 '16 at 14:01
thanks for asking. unfortunately the problem still exists. BTW can you give an example for using indexes.i want to use dates in my case '{} ({:%I:%M %p} - {:%I:%M %p})', – Grizzled Squirrel Oct 26 '16 at 10:42
@GrizzledSquirrel Try this `{0} ({1:%I:%M %p} - {2:%I:%M %p})` – Sardorbek Imomaliev Oct 26 '16 at 11:00
if you consider this :_('{0}').format( 'Morning'), the value Morning is supplied at (if i can use) runtime. In the po file well it'll be: #, python-brace-format msgid "{0}" msgstr "{0}" there should be another way to get out of this wierd stuff – Grizzled Squirrel Oct 26 '16 at 11:07
@GrizzledSquirrel So is it working or not? Also you need to translate morning separtely. Don't forget that your code is parsed by a script and it may not know how to handle your case, sometimes you need to do things manually. – Sardorbek Imomaliev Oct 26 '16 at 11:18
No its not working., _('{0}').format(_('Morning')) in this case, i am trying to use plain text alone.,why it would not work? thanks – Grizzled Squirrel Oct 26 '16 at 12:26
@GrizzledSquirrel It should be just "Moring" `_('{0}').format('Morning') `. Why you are wrapping it in ugettext? – Sardorbek Imomaliev Oct 27 '16 at 05:58
somehow this is working fine except that date format is not coming as translated [code] _(u'{period} ({start_date:%I:%M %p}').format(period=_('Morning'), start_date=mydatetimefunction()) [code] – Grizzled Squirrel Oct 31 '16 at 10:15
