How can I change the language of a whole Django CMS website?

I would like to change the language of a website written with the Django CMS from en-us to de in a way that all present contents in en-us will be shown for de in the future.

I tried

Page.objects.all().update(languages='de')

but afterwards there were 404 Errors everywhere.

What else do I have to change?

The accepted answer is not compatible with the newer versions of Django CMS. The language attribute has been changed into languages (also see https://stackoverflow.com/a/56162296/522248). For draft mode versions of your pages, this contains a comma separated list of available languages. Simply searching for the exact language and updating it to the next version won't work.

Given we want to change 'nl' into 'nl-nl', the following should match:

nl,en,de
de,nl,en
en,de,nl
nl

We can't just search for 'nl', because the following must not match:

nl-nl
nl-nl,en

My solution:

from_lang = 'nl'
to_lang = 'nl-nl'

# Match our lang at start, middle or end of list
lang_regex = r'^(.*,)?{}(,.*)?$'.format(from_lang)

# Get all distinct combinations of languages that contain our language
language_combinations = Page.objects\
    .filter(languages__regex=lang_regex)\
    .values('languages')\
    .distinct()

# Create a mapping for each combination, replacing the old for the new lang
language_mappings = [
    (
        page['languages'],
        re.sub(lang_regex, '\\1{}\\2'.format(to_lang), page['languages'])
    ) for page in language_combinations
]

# Update all pages to new lang
for old_languages, new_languages in language_mappings:
    Page.objects\
        .filter(languages=old_languages)\
        .update(languages=new_languages)

# Also update Title and CMSPlugins
Title.objects.filter(language=from_lang).update(language=to_lang)
CMSPlugin.objects.filter(language=from_lang).update(language=to_lang)

To add to @ojii's answer, with django-cms 3.6.0 & django 1.11.20 the procedure now is:

  1. Modify settings.py:
#LANGUAGE_CODE = 'en-us'
LANGUAGE_CODE = 'en'
  1. Update Pages, Titles, CMSPlugins (note the languages for Pages):
Page.objects.filter(languages='en-us').update(languages='en')
Title.objects.filter(language='en-us').update(language='en')
CMSPlugin.objects.filter(language='en-us').update(language='en')

To change the language codes for all content on a django CMS site, run these commands (switching from 'en-us' to 'de':

Page.objects.filter(language='en-us').update('de')
Title.objects.filter(language='en-us').update(language='de')
CMSPlugin.objects.filter(language='en-us').update(language='de')
