delete_all vs destroy_all?

by

You are right. If you want to delete the User and all associated objects -> destroy_all
However, if you just want to delete the User without suppressing all associated objects -> delete_all

According to this post : Rails :dependent => :destroy VS :dependent => :delete_all

  • destroy / destroy_all: The associated objects are destroyed alongside this object by calling their destroy method
  • delete / delete_all: All associated objects are destroyed immediately without calling their :destroy method
