How can I get the current language in Django?

You can use these template tags in Django's templating language:

{% load i18n %}

{% get_current_language as LANGUAGE_CODE %}

Current language code: {{ LANGUAGE_CODE }}<br>

{% get_current_language_bidi as LANGUAGE_BIDI %}

{% if LANGUAGE_BIDI %}RTL <br>{% endif %}

{% get_language_info for LANGUAGE_CODE as lang %}

Language code: {{ lang.code }}<br>
Name of language: {{ lang.name_local }}<br>
Name in English: {{ lang.name }}<br>
Bi-directional: {{ lang.bidi }}
Name in the active language: {{ lang.name_translated }}
