Django Internationalization Issue

[Tiago Borges]

I have a application in django 2.2 to translate just as below:

LANGUAGES = (
        ('pt', _('Portuguese')),
        ('en', _('English')),
        ('es', _('Spanish')),
    )

LANGUAGE_CODE = 'en'
USE_I18N = True

The translation itself is working on the templates and for the default language (LANGUAGE_CODE). The issue lies on the translation triggering. Since this is for a REST api, I will not be using cookies or sessions, the translation needs to watch the Accept-Language header. Debugging the Locale middleware, I can confirm that the correct language is being found, but the translated text are returned always for the default language (LANGUAGE_CODE), ignoring the language found by the middleware. If I replace the LANGUAGE_CODE for pt or es, it works just fine. The django docs states that LANGUAGE_CODE was supposed to be the last fallback.

There is not enough elements in your report to demonstrate that Django is at fault. You may try to provide a failing test, or use first a support channel to ensure that this is a bug in Django.
