Empty catalog when internationalizing JavaScript code

I'm trying to set up Internationalization of JavaScript code in my Django application.

My Django app has a locale subdirectory with a properly generated djangojs.po file. The package definition is as follows:

# urls.py
js_info_dict = {
    'packages': ('my_project',),
} 

./manage.py makemessages worked well as the .po file contains all the to-be-translated strings but开发者_高级运维 no JavaScript string ever gets translated on the website and the catalog is always empty.

I also had some problems with. This is how it works for me:

Add this to yr root urls.py:

js_info_dict = { 'domain': 'djangojs',
                 'packages': ('YOUR_PROJECT_NAME',), }


urlpatterns = patterns('',                   

    #enable using translation strings in javascript
    #source: https://docs.djangoproject.com/en/dev/topics/i18n/translation/#module-django.views.i18n
    (r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),

)

In JS files use:

var somevar = gettext('Text to translate');

To compile django translation files: In a shell/terminal run from the project root (where 'apps', 'settings', etc lie):

#for "normal django files" (.py, .html):
django-admin.py makemessages --locale=de
#for javascript files. source: http://stackoverflow.com/a/3571954/268125
django-admin.py makemessages -a -d djangojs --locale=de
#to compile the translation files to machine code
django-admin.py compilemessages --locale=de

i added my_project to INSTALLED APPS in settings.py and that seemed to do the trick
