Posted by pei_______ on 2022-06-20

learning from 100 Days of Code: The Complete Python Pro Bootcamp for 2022


The Movie DB API - Documentation
sqlalchemy - order_by


Learning Points

Point 1. db.session.query(Movie).order_by(Movie.rating)
Point 2. Get the args from query
Point 3. Find a movie by primary key
Point 4. Check if POST requests is success
Point 5. Get the data from POST requests and update db
Point 6. Virtual page just for some functions
