Trying to get flask-babel to work in a factory method. I've got it working in a simple flask app (without a factory) but as soon as I try using an app factory the "gettext" or "_" doesnt seem to translate the text.
I found this other very similar issue and as I dont see any errors I assume I've set it up correctly: Access a Flask extension that is defined in the app factory
Setup up a demo flask app (with factory) as per below:
# __init__.py
from flask import Flask
from flask_babel import Babel, gettext
from application.webapp import server_bp
babel = Babel()
def create_app(config_filename=None):
app = Flask(__name__)
babel.init_app(app, "de")
app.register_blueprint(server_bp)
return app
# webapp.py
from flask import Flask, Blueprint
from flask_babel import gettext
server_bp = Blueprint("main", __name__)
# app = Flask(__name__)
# babel = Babel()
# babel.init_app(app, "de")
@server_bp.route("/")
# @app.route("/")
def hello_world():
return gettext("Title of Dash App")
# wsgi.py
from application import create_app
app = create_app()
if __name__ == "__main__":
app.run(host="0.0.0.0", port=5004)
I follow the exact steps provided by the flask_babel docs here https://python-babel.github.io/flask-babel/ and translate the
and i tried to hardcode the lang (which worked in the non-factory) in this line in the init.py file
# __init__.py
...
babel.init_app(app, "de")
...
and the
But for some reason I don't understand the translation does not work at all when using an app factory method. Any help or guidance would be sincerely appreciated :)
