In my Django 2.0 site, I want to set the lang atribute of the html tag to the current locale's language. In my base.html which other templates extend, I use get_current_language in the following way
{% load i18n %} {% get_current_language as LANGUAGE_CODE %} <!DOCTYPE html> <html lang="{{ LANGUAGE_CODE }}"> ... </html> The site has translations for multiple languages. If I switch the language in the browser, I see the correct translations, but the lang attribute will always contain en.
In my settings.py I have
USE_I18N = True LANGUAGE_CODE = 'en-us' and based on the suggestion of Goran the following middleware order
MIDDLEWARE = [ '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', ] The LANGUAGES setting is unset.
As suggested by Kostadin Slavov I have tried printing the language from the view. It seems that get_current_language calls django.utils.translation.get_language, so I have inserted the following in my view
from django.utils import translation print(translation.get_language()) It prints the correct value (eg de when accessing the view with a browser set to German).
What else am I missing?

I tried to simulate your environment with these steps:
$ cd ~ $ python3 -m venv ~/venvs/mysite $ source ~/venvs/mysite/bin/activate $ pip install django==2.0.8 $ django-admin startproject mysite Then I updated the generate code as in your example:
mysite/settings.py
... MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', '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', ] ... TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': ['templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] ...mysite/urls.py
from django.contrib import admin from django.urls import path from django.views.generic.base import TemplateView urlpatterns = [ path('', TemplateView.as_view(template_name='base.html'), name='home'), path('admin/', admin.site.urls), ]templates/base.html
{% load i18n %} {% get_current_language as LANGUAGE_CODE %} <!DOCTYPE html> <html lang="{{ LANGUAGE_CODE }}"> <body> <pre>LANGUAGE_CODE = {{ LANGUAGE_CODE }}</pre> <body> </html>
With the Django generated code and my few above updates I can see different language code if I switch the language of my browser visiting http://localhost:8000/ after starting it with:
$ python manage.py runserver Try my steps on your local environment and check if it works, and then compare your project to the code above.
Update
Try to use diffsettings to see "differences between the current settings file and Django’s default settings".
