translating strings from database flask-babel
It's not possible to use Babel in database translations, as database content is dynamic and babel translations are static (they didn't change). 
If you read the strings from the database you must save the translations on the database. You can create a translation table, something like (locale, source, destination), and get the translated values with a query.
I'm using Flask-Babel for translating string.
In some templates I'm reading the strings from the database(postgresql). 
How can I translate the strings from the database using Flask-Babel?
