Salut Olivier.
routers = dict(
BASE = dict(
domains = {
}
),
my_app = dict(languages=['en', 'fr'], default_language='fr'),
)
The original website (words in the .html files) have to be in english.
After you must edit fr language file for applying translations.
For example:
T('A beautiful journey')
Load one time the .html page.
Search for 'A beautiful journey' in the fr language file.
Translate and save.
For bigger contents make double fields in tables:
product_description_en
product_description_fr
And in the .html file test which is the request.uri_language for displaying one or the other field.
Hopes it could help, bye.
