Flask-sqlalchemy 's session problem?

if you configure

in your flask configuration file config.py

SQLALCHEMY_TRACK_MODIFICATIONS = True
SQLALCHEMY_COMMIT_ON_TEARDOWN = True

then you no longer need to explicitly write db.session.commit () in the program.

Does

mean that the object is used across threads? Can you tell me the complete business scenario?

I don't know your complete business scenario, but if you cross threads, you usually need to pass app_context.

 
app_context = flask.current_app.app_context()

-sharp app_context
with app_context:
