7447	QuerySet.update() bypasses custom Model.save() methods	Johannes Dollinger	nobody	"This is symmetrical to #6915 (and therefore should be handled simmilar). Options:

  * iterate the queryset, update and save() each instance individually. Because this would also work for sliced querysets #7298 would deserve a better fix then.
  * {{{assert not self.has_custom_save(), ""Cannot update a query for a model with a custom save() method.""}}}. This will probably break `ManyRelated` managers.
  * only add a big warning to `QuerySet.update()` and `Model.save()` doc. This doesn't help at all to solve the issue.

+1 for the first option."		closed	Database layer (models, ORM)	dev		fixed	qsrf-cleanup		Design decision needed	0	0	0	0	0	0
