Django 元组/选择字段未翻译

Question

I have an Integer ModelField with a set of choices.

field = models.IntegerField(choices=CHOICES_CONSTANT)

This CHOICES_CONSTANT is defined in another file and imported

CHOICES_CONSTANT = (
    (0, _('One')),
    (1, _('Two')),
    ...
)

The _ is from from django.utils.translation import ugettext_lazy as _ as the model field requires you to use lazy translations.

I also import the CHOICES_CONSTANT into other files (such as reports) where in a report I might say str(dict(CHOICE_CONSTANT)[object.field]) if object.field else '' .

This str(dict(CHOICES_CONSTANT)[object.field]) if object.field else '' does not get translated. In fact, if I just print(CHOICES_CONSTANT) it immediately evaluates to the default language (English).

In other places I would do object.get_field_display() and that also does not translate.

Any help would be much appreciated.

Answer 1

I spent too long on this looking in the wrong direction...

The lazy loaded translations were working correctly. The issue was that LOCALE_PATHS in settings.py did not include the root directory locale/ folder. The constants CHOICES_CONSTANT and others were store in the project directory, rather than an app so the app was not getting the translations from the root directory.
