Given a lazy/functional choice generator for a model, Django's
internationalization cannot fully comprehend the lazy localizable text
generated by the function.

Imagine a base class:
{{{
# gettext_lazy also does not work
from django.utils.translation import gettext as _

class SelectableModelField:
@classmethod
def make_choices(cls):
return [(value, _(key.replace('_', ' '))) for (key, value) in
vars(cls).items()
if not (key[-1] + key[0]).__contains__('_')]

bool_choices = ((True, 'Yes'), (False, 'No'))
}}}

which is inherited by:

{{{
class User(models.Model):
class __UserType__(SelectableModelField):
basic = 0
premium = 1

user_type =
models.PositiveSmallIntegerField(choices=__UserType__.make_choices())
}}}

the ''django.po'' file will not contain the functionally-generated choices
after running ''python manage.py makemessages -l ...''

Comment:

Thanks for this ticket, however I don't think it's feasible (not only in
Django but in general). You can only translate a fixed list of strings.
