How to use django.views.i18n.set_language() function?

Question

I read a tutorial in Django site but I don't understand how to use the set_language() function. For example, I have a demo follow as:

index.html

{% trans "Hello World." %}

<form action="/i18n/setlang/" method="post">
{% csrf_token %}
<input name="next" type="hidden" value="/next/page/" />
<select name="language">
{% get_language_info_list for LANGUAGES as languages %}
{% for language in languages %}
<option value="{{ language.code }}">{{ language.name_local }} ({{ language.code}})</option>
{% endfor %}
</select>
<input type="submit" value="Go" />
</form>

urls.py

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

views.py

What need I write to display the languages, which were chosen from user in this file?

Thanks,

With the code you are using, you don't need to write your own views. The form will make a POST request to /i18n/setlang/, with the language code and (optional) the redirect-to (next) page as parameters.

The django view does the following (from the django documentation)

Django looks for a next parameter in the POST data. - If that doesn't exist, or is empty, Django tries the URL in the Referrer header. - If that's empty -- say, if a user's browser suppresses that header -- then the user will be - redirected to / (the site root) as a fallback.

So in essence, the user will be redirected after submitting the form, and the django view will set the language for that user according to what was submitted.

Hope this helps,
