Flask-Babel and using url prefix

Flask-Babel and using url prefix

From:

Hello all,

I'm using Flask-Babel to do some i18n stuffs
.
So far, I can customize the get_locale to extract locale from request.args
(e.g. http://localhost:5000/?lang=vi)

@babel.localeselector
def get_locale():
    return request.args.get('lang', 'en')

If I config the urls to encode locale in the url prefix like
http://localhost:5000/en/,
how can I
1) extract it (other than manually parse request.path) and
2) organize the routings so that I don't have to repeat the <lang> prefix

@app.route('/<lang>/admin')
def admin():
     pass
@app.route('<lang>/post')
def ...

Can app.register_module(admin, url_prefix='<lang>') do that?

thanks,

Yes, you need a trailing slash though:

    app.register_module(admin, url_prefix='/<lang>')

You could also subclass Flask to override the route function to always 
prefix the URL rule with "/<lang>" unless a certain parameter is set.

Thanks Armin, subclassing Flask is a propably the good way to implement my
stuffs.

Regarding app.register_module, I mean the '<lang>' is a parameter,
not fixed.  Can a module be registered with a paramterized url_prefix and
function get_locale could extract that prefix.

Yes, that is possible.  There is no restriction on the prefix.

Hi,

I need a language code at all times but i don't want to hande the language
code in my views so i did a little @app.before_request middleware with:

language_code = request.view_args.pop('language_code', None)
g.context['language_code'] = language_code

I've also overridden url_for to add:
if endpoint != 'static':
    if not 'language_code' in values:
        values['language_code'] = g.context['language_code']

Then in @babel.localeselector:
return g.context['language_code']


Works great.

Regards,
