Requires {% load i18n %}
Add {% load i18n %} near the top of any template that
uses {% language %}. Without it Django does not
know the name and raises TemplateSyntaxError.
Renders a block in a specific language, whatever the request's language happens to be.
Template
{% load i18n %}
{% language "fr" %}
{% translate "Welcome back" %}
{% endlanguage %}
Useful when one page has to carry more than one language at once — a notification previewed in the recipient's language rather than the sender's.
