change i18n language through hyperlinks

[Chuck Bai2]

I want to allow user select language preference through clicking the
language hyperlinks like "_English_ | _French_" switch. And I also want
to redirect back to the previous page after clicking the language
switch. Is it possible to use Django view:
django.views.i18n.set_language? In the documentation, there is an
example using form submit to select language using this view.

<form action="/i18n/setlang/" method="post">
<input name="next" type="hidden" value="/next/page/" />
<select name="language">
{% for lang in LANGUAGES %}
<option value="{{ lang.0 }}">{{ lang.1 }}</option>
{% endfor %}
</select>
<input type="submit" value="Go" />
</form>

But I want to implement this using hyperlinks and want to know how.

You'll need to write your own view to handle this (you could look at
Django's view for inspiration). Django intentionally doesn't support
this because it's bad practice (using a GET request to initiate a state
change).

Even then you want in get method you can use the below code.

In view

from django import http
from django.utils.translation import check_for_language
from django.conf import settings

def set_language(request, lang_code):
"""
Patched for Get method
"""
next = request.REQUEST.get('next', None)
if not next:
next = '/'
response = http.HttpResponseRedirect(next)
if lang_code and check_for_language(lang_code):
if hasattr(request, 'session'):
request.session['django_language'] = lang_code
else:
response.set_cookie(settings.LANGUAGE_COOKIE_NAME,
lang_code)
return response

And in template
<ul class="language_holder">

{% for lang in LANGUAGES %}

<a href="/setlang/{{ lang.0 }}/">{{ lang.1 }}</a>&nbsp;&nbsp;

{% endfor %}

</ul>

in urls
url(r'^setlang/(?P<lang_code>.*)/$', 'utils.views.set_language')

I dont know it is a good practice to do

thanks Satheesh, the set_language function is partially working for
me. When I click the lauguage hyperlinks, only the word "Home" works,
but when I change the msgid to be "Home1", it stop working. It seems
that "Home" is a django preserved word which get auto-translated.

1. In my base.html, I have

{% load i18n %}

{% trans "Home1" %}

2. django.po and django.mo files are generated correctly for the
lauguages.

msgid "Home1"
msgstr "My_Translation"

3. In my settings.py, I have

USE_I18N = True

LANGUAGE_CODE = 'en-us'

MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.locale.LocaleMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
)

4. syncdb is done, and session table is generated.

5. language preferrence selection is like the code below.

I don't know which piece is missing. Anyone can suggest? Thanks.

try this

def set_language(request, lang_code):

next = request.REQUEST.get('next', None)
if not next:
next = '/'
response = http.HttpResponseRedirect(next)
if lang_code and check_for_language(lang_code):

settings.LANGUAGE_CODE=lang_code
return response

[Ozgur Odabasi]

wow this is dangerous!

Changes language settings for all users ;P
But I couldnt unerstand how session and cookie frameworks works,
documented examples doesn't work...
