+1 on signals

[@bugbytes3923]

Will look into it! Thanks

[@Peterstavrou]

I've noticed that by default most people simply use the .save() method when updating single fields rather than specifying specific fields such as restaurant.save(update_fields=['name']). Is there much performance improvement specifying specific fields or should we stick to .save() for ease?

[@bugbytes3923]

I think that update_fields can help if you have a lot of database overhead, as it does cut down the data that's being sent to the DB server. But for most apps, it won't really have much impact I don't think. save() should work fine!
Might be interesting to do a video on load testing with these two (and other) techniques to try and quantify the performance difference. Might look into that!

[@thinkingcitizen]

Thanks so much man. Had an interesting observation in my SQL - My .save(update_fields=...) executed 50% SLOWER than my regular .save( ) ! Is this expected or is something wrong with my sqllite? Intuitively, I thought the opposite would happen.

[@bugbytes3923]

That's interesting. No idea why that happens with SQLite. I agree, I'd have expected the opposite!
