django翻译不起作用，但模板中的翻译有效

Question

I try to translate my django site to another languages but translation in python doesn't work. But translation in templates using trans tag, works as expected.

I have tried ugettext , gettext , gettext_lazy and ugettext_lazy , and every time I got original untranslated strings.

My sources all in utf-8 encoding, original strings in Ukrainian language

Answer 1

You want to check this

Since you didn't post your code, I assume it has something to do with the alias.

Use

from django.utils.translation import ugettext_lazy as _

translated_string = _('original_string')

And you should not have a problem

"You can only use the _ alias for ugettext and ugettext_lazy (or any other related translation function) in Django or else it won't be recognized by makemessages command. The technical explanation can be found in Robert Lujo's answer ."

Answer 2

I think the problem lies in your MIDDLEWARE_CLASSES . The thing is, there are some middlewares that might change your request, including a language prefix. Especially, when you use AJAX calls for querying extra template data, translated by ugettext, gettext, etc.

Answer 3

The ugettext_lazy will not work if string contains non Latin symbols. So in my case the original strings must be the Unicode objects.
