translating strings from database flask-babel

Question

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 da

Answer 1

I would suggest having a engineering text in the database. And in your HTML file (or preferably a HTML you can include everywhere) you have a script with the translations:

<script>
  translations = { 'WillBringOwnFood': {{ _('Guest will bring their own food')}},
                   'WantToShareBathroom': {{ _('Guest would like to share bathroom with stranger')}}  };
</script>

Now when you receive the engineering string you just do a lookup in your translations dictionary. So the .js file would look something like this:

function receiveDBCallback(response) {
    $('.guestWishes').text(translations[response]);
}

Then you can use babel as usual to extract your strings. And you will have all your translations in the same .po/mo file.

Answer 2

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.
