28268	Feature: Clear cached_property on related DB operations.	Özer Sahin	nobody	"Hey,

I am wondering, why it wouldn't be smarter to let the decorator (somehow) clear related caches whenever a related model changes. 

Use Case:

I have a big model with many related models and I need to filter them for a ListView Page. To display those values I would use cached_property for data from other models like images. Since the related instances have not changed, we could use the cached_property. Now if we upload a new image, a signal could clear the cached_property used in the other model. The same goes for update, delete or other relevant operations. That way the system would always be up to date, but max out the potential of caching where ever it makes sense.

Is that clear? I am not an expert like you, but since I am currently learning about all this, I was curious why this hasn't been implemented (yet)."	New feature	closed	Database layer (models, ORM)	1.11	Normal	wontfix	cached_property		Unreviewed	0	0	0	0	0	0
