How can I use advanced filtering in Flask ORM?

You can use advanced filtering in Flask ORM by utilizing the filter method with various conditions. For example, you can combine multiple filters using and_ or or_ from SQLAlchemy.

Can you give me an example of combining filters?

Sure! You can combine filters like this: session.query(User).filter(and_(User.age > 18, User.city == 'New York')).all().

What if I want to filter by a related model?

You can filter by related models using the dot notation. For example: session.query(Order).filter(Order.user.has(User.age > 18)).all().

Are there any performance considerations I should keep in mind?

Yes, when using advanced filtering, be mindful of the number of joins and the size of the dataset, as they can impact performance.
