django i18n_patterns hide default lang_code from url

Question

I\'m using the i18n_patterns to add a prefix of current lang_code to my url.

urlpatterns += i18n_patterns(\'\',
    url(r\'^\', include(\'blaszczakphoto2.gal

This is my solution:

Create django middleware: django_app/lib/middleware/locale.py

from django.utils import translation

    class SwitchLanguageMiddleware(object):

        def process_request(self, request):
            lang = request.GET.get('lang', '')

            if lang:
                translation.activate(lang)
                request.LANGUAGE_CODE = translation.get_language()

        def process_response(self, request, response):
            request.session['django_language'] = translation.get_language()
            if 'Content-Language' not in response:
                response['Content-Language'] = translation.get_language()
            translation.deactivate()

            return response

It's read the get parameter of request and if it has lang attribute, then switching language. Ex.: /about-us/?lang=pl

Include this middleware to settings.py:

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

    'django_app.libs.middleware.locale.SwitchLanguageMiddleware',
)
