Django language change ignored, remains default

Question

I'm using Django 1.6, and I feel like I'm missing something, but cookies are set to current language chosen, but the display language stays the default.

Corresponding code:

settings.py

LANGUAGES = (
    ('hu', 'Hungarian'),
    ('en', 'English'),
)

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "django.core.context_processors.static",
    "django.core.context_processors.tz",
    "django.contrib.messages.context_processors.messages",
    "django.core.context_processors.request"
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware'
)
LANGUAGE_CODE = 'en-US'
TIME_ZONE = 'CET'
USE_I18N = True
USE_L10N = True
USE_TZ = True

urls.py

urlpatterns = patterns('',
    url(r'^i18n/', include('django.conf.urls.i18n')),
    ...
)

template

{% extends 'base.html' %}
{% load i18n %}
...
<h4>{% trans "Modern Technologies" %}</h4>
...

I ran makemessages -a to create the lang files, rosetta is installed and languages are edited. Then I've ran compilemessages. Checking in Chrome the cookie "django_language" get's set correctly. But the actual text is still the default "Modern Technologies".

Answer 1

Your middleware order is different from that recommended by the documentation:

To use LocaleMiddleware, add 'django.middleware.locale.LocaleMiddleware' to your MIDDLEWARE_CLASSES setting. Because middleware order matters, you should follow these guidelines:

• Make sure it’s one of the first middlewares installed.
• It should come after SessionMiddleware, because LocaleMiddleware makes use of session data. It should also come before CommonMiddleware because CommonMiddleware needs an activated language in order to resolve the requested URL.
• If you use CacheMiddleware, put LocaleMiddleware after it.

So your middleware configuration should look like this:

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

You also need to remember to include the LOCALE_PATHS setting in your settings file:

LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'locale'),
)

Answer 2

Okay, the problem was, that I've put my locale folder into root, and it expects it inside an installed app.

However rosetta finds it even if you have the translation outside an app.

Answer 3

Try insert 'django.middleware.locale.LocaleMiddleware', between SessionMiddleware and CommonMiddleware.

As it makes in docs. If I'm not mistaken, it's important.
