Flask, one flash message not getting displayed [duplicate]

I have updated one view. It used to call the flask route from a javascript window.location function but now am using $.post() to send parameters to the route. The location of the flash call hasn't changed (I put a print statement just before it and that executes so I know the interpreter gets to the flash call). All code in the route's method executes correctly but the flash message does not show and I am at a loss. Nothing coming up from Google searches. Here are the last 3 lines in the route method db.session.commit() flash('Database Updated') return redirect(url_for('index'))
