How can I optimize my SQLAlchemy queries in Flask?
To optimize SQLAlchemy queries in Flask, consider using eager loading, indexing your database, and avoiding N+1 queries.
What is eager loading and how does it help?
Eager loading fetches related objects in a single query, reducing the number of database hits and improving performance.
Can you give me an example of how to implement eager loading?
Sure! You can use the joinedload option in your query like this: session.query(User).options(joinedload(User.posts)).all().
What are some common mistakes to avoid when using SQLAlchemy?
Common mistakes include not using indexes, failing to use transactions, and not properly managing sessions.
