… mode) get_locale() used setattr()/hasattr() against Flask's session and the request's cookie MultiDict, neither of which expose their contents as attributes, so the session/cookie fallback branches never actually fired. Read and write PGADMIN_LANGUAGE via dict-style access instead, so the selected language persists across requests via the session and the PGADMIN_LANGUAGE cookie that is already set correctly elsewhere. Closes pgadmin-org#10347

- Around line 331-336: Update the language-preference assignment in the session
handling flow to use the mapping key PGADMIN_LANGUAGE via session item
assignment, so FileBackedSessionManager.put() persists it and get_locale() can
retrieve it on later requests.

setattr(session, ...) here has the identical problem fixed in get_locale(): it sets a plain instance attribute rather than a session dict entry, so it never reaches the serialised session. Use dict-style assignment instead, per CodeRabbit's review on PR pgadmin-org#10351.

Summary
get_locale()inweb/pgadmin/__init__.pyusedsetattr()/hasattr()against Flask'ssession(a dict-likeSecureCookieSession) andrequest.cookies(aMultiDict), neither of which expose their contents as object attributes. As a result the session/cookie fallback branches never fired, and the UI silently reverted to English on every request that didn't include thelanguageform field.session['PGADMIN_LANGUAGE'] = ...,'PGADMIN_LANGUAGE' in session,request.cookies.get(...)) so the selected language persists via the session and thePGADMIN_LANGUAGEcookie that other parts of the app (preferences,browser) already set correctly.Test plan
web/pgadmin/tests/test_get_locale.py, exercising the registered Babellocale_selectordirectly for all three branches (form field, session, cookie fallback). Confirmed it fails against the pre-fix code and passes with the fix.pycodestyleclean on the changed/added files.Closes #10347
