What are some common mistakes when using ORMs?

What are some common mistakes when using ORMs?

Some common mistakes include not understanding lazy loading, over-fetching data, and ignoring performance implications.

Can you explain lazy loading and why it's a mistake?

Lazy loading can lead to performance issues if not managed properly, as it may result in multiple database calls instead of a single optimized query.

What about over-fetching data? How does that happen?

Over-fetching occurs when you retrieve more data than necessary, often due to poorly defined queries or fetching entire objects instead of just needed fields.

How can I avoid these mistakes?

To avoid these mistakes, always optimize your queries, use pagination, and be mindful of the data you actually need for your application.
