I've been struggling on an app for a week. This is the first time I heard anyone explain this and it's like a light bulb went off. Lol.

Well done! thank you.

I did an includes request to fetch certain data. Now on this data if I were to set some attributes to some new values (based on some conditions) I end up auto firing an update to the db. Is this the expected behaviour? Should I be setting the attributes on a different instance and use only getters on the data fetched via the includes? Please do help
