Recently I had been working on website made 2 or 3 years ago by my predecessor (I write this because app is a mess and it's not my fault). Boss asked me to make it multilingual just simply adding English version. I followed instructions from djangoproject docs, made nice .po and .mo files in locale directory, set urls for i18n views and added form with proper select to HTML. The problem is, when I send POST with language code to setlang view from i18n, django do not change language nor throw any errors. Unfortunately, in 1.6.5, django.utils.translation doesn't have LANGUAGE_SESSION_KEY, so I don't even know how should I change session data... So, here you have my settings:

In urls.py I just added:
url(r'^lang/', include(i18n))
which I'm using with form:
<form action="/lang/setlang/" method="post">
{% csrf_token %}
<input type="submit" value="{% trans 'Zmień język' %}" />
<select name="language">
{% for language in st.languages %}
<option value="{{ language.code }}"{% if language.code == LANGUAGE_CODE %} selected="selected"{% endif %}>
{{ language.name_local }} ({{ language.code }})
</option>
{% endfor %}
</select>
</form>
st.languages is just:
'languages': [
{'code': 'pl',
'name_local': 'polski'},
{'code': 'en',
'name_local': 'english'}]
Anyone?
