Choose language for embedded dashboard

[aehanno]

How I can specified language when I display my embedded dashboard ?
Is it possible to specify it in the guest token or in the SDK method (supersetEmbeddedSdk.embedDashboard) ?

Thanks

@aehanno have you found any workaround yet?

[aehanno]

@c2ofh, No, I found anything
Do you have a need on this topic too ?

@aehanno I found this for 2 days. I am very interested in this issue.

I had no success setting the language via an API call (Superset runs embedded in an iframe -> session mismatch).

This worked for me:

CustomSecurityManager.py: |
import jwt
import json
import sys
import time
from flask_appbuilder.security.views import AuthDBView
from flask_appbuilder import expose
from superset.security.manager import SupersetSecurityManager
from flask import abort, current_app, flash, g, redirect, request, session, url_for
from flask_login import login_user, logout_user
class CustomAuthDBView(AuthDBView):
login_template = 'appbuilder/general/security/login_db.html'
@expose('/login/', methods=['GET', 'POST'])
def login(self):
lang = request.args.get('lang')
if lang:
print("Setting Lang from request: " + lang, file=sys.stderr)
session["locale"] = lang

You have to configure your CustomSecurityManager;

superset_config.py : |
from xxx import CustomSecurityManager
CUSTOM_SECURITY_MANAGER = CustomSecurityManager

Oh I see, can be a good solution but on my side I didn't use OAuth to embedded my dashboard

@christophatinnuce how did you send the lang parameter to the API?

I had the same problem, implemented it by using a mutator:

Superset config file:

BABEL_DEFAULT_LOCALE = "en"
BABEL_DEFAULT_FOLDER = "superset/translations"
LANGUAGES = {
    "en": {"flag": "us", "name": "English"},
    "es": {"flag": "es", "name": "Spanish"}
}

def set_locale_from_url_param():
    from flask import session, request
    locale_param = request.args.get('lang')
    if locale_param:
        supported_locales = ['en', 'es']
        if locale_param in supported_locales:
            session["locale"] = locale_param

FLASK_APP_MUTATOR = lambda app: app.before_request(set_locale_from_url_param)

And when emedding the dashboard, add this url param to the dashboardUIConfig

dashboardUiConfig: {
     urlParams:{
          lang: 'es'
}
