Django: multi language

1. FlatPages

This approach doesn't work any more (Django > 1.2) !

svn checkout http://django-multilingual.googlecode.com/svn/trunk/ django-multilingual-read-only
cd django-multilingual-read-only
sudo python setup.py install
Follow the instructions:

Check that SITE ID is correct!
2. Add dictionaries
1. Add trans or blocktrans to html you want to be transalted:
e.g., {% trans "Home" %}
2. also, add {% load i18n %} to the beginning of html.


3. Generate dictionaries (.po):
3.1 Set PYTHONPATH (export $PYTHONPATH=/path/to/your/project/)
3.2 Execute: django-admin.py makemessages -l ru . It will generate .po files in locale/ru/LC_MESSAGES
open the file and add translation. It will look like:
#: templates/flatpages/default.html:15
msgid "About"
msgstr "О нас"
3.3 Compile the files:
django-admin.py compilemessages
If you update the files you should use:makemessages -a
4. Add form to switch languges:
html:

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

Urls.py: (r'^i18n/', include('django.conf.urls.i18n')),

Settings.py:
LANGUAGES = (
        ('ru','Russian'),
        ('en','English'),
)
