So yes English is the default language for GeoNode, it is only different if it has been changed by the user not depending on location or other factors.
GeoNode’s default language is English, but GeoNode users can change the interface language with the pulldown menu at the top-right of most GeoNode pages. Once a user selects a language GeoNode remembers that language for subsequent pages.
Unless as mentioned here by GeoNode:
Unfortunately Django overrides this setting, giving the language setting of a user’s browser priority. For example, if LANGUAGE_CODE is set to French, but the user has configured their operating system for Spanish they may see the Spanish version when they first visit GeoNode.
GeoNode provides a list of languages that can be selected,
A list of language codes can be found in the global django config file /usr/local/lib/python2.7/dist-packages/django/conf/global_settings.py (or /var/lib/geonode/lib/python2.7/site-packages/django/conf/global_settings.py if GeoNode has been installed using apt-get).
For example, to make French the default language use:
LANGUAGE_CODE = 'fr'
Now if you would like the user's browser not to change languages and keep the default as desired (in this case English) GeoNode provides the following:
Additional Steps
If this is not the desired behaviour, and all users should initially see the default LANGUAGE_CODE, regardless of their browser’s settings, do the following steps to ensure Django ignores the browser language settings. (Users can always use the pulldown language menu to change the language at any time.)
As root create a new directory within GeoNode’s site packages:
mkdir /usr/lib/python2.7/dist-packages/setmydefaultlanguage
or::
mkdir /var/lib/geonode/lib/python2.7/site-packages/setmydefaultlanguage
if GeoNode has been installed using apt-get.
As root create and edit a new file /usr/lib/python2.7/dist-packages/setmydefaultlanguage/init.py and add the following lines:
class ForceDefaultLanguageMiddleware(object):
"""
Ignore Accept-Language HTTP headers
This will force the I18N machinery to always choose settings.LANGUAGE_CODE
as the default initial language, unless another one is set via sessions or cookies
Should be installed *before* any middleware that checks request.META['HTTP_ACCEPT_LANGUAGE'],
namely django.middleware.locale.LocaleMiddleware
"""
def process_request(self, request):
if request.META.has_key('HTTP_ACCEPT_LANGUAGE'):
del request.META['HTTP_ACCEPT_LANGUAGE']
At the end of the GeoNode configuration file /home/geonode/geonode/geonode/settings.py (or /etc/geonode/settings.py if GeoNode has been installed using apt-get) add the following lines to ensure the above class is executed:
MIDDLEWARE_CLASSES += (
'setmydefaultlanguage.ForceDefaultLanguageMiddleware',
)
Restart
Finally restart Apache as root with:
service apache2 restart
