An example of an AI chatbot conversation about advanced usage of Flask-SQLAlchemy.
How can I optimize my Flask-SQLAlchemy queries?
You can optimize your queries by using techniques like eager loading, query filtering, and indexing your database.
What is eager loading and how does it help?
Eager loading retrieves related objects in a single query, reducing the number of database hits and improving performance.
Can you give an example of using eager loading in Flask-SQLAlchemy?
Sure! You can use the joinedload option in your query like this: session.query(User).options(joinedload(User.posts)).all().
What are some common pitfalls to avoid with Flask-SQLAlchemy?
Common pitfalls include not using transactions properly, failing to close sessions, and not handling lazy loading correctly.
