For :class:~django.db.models.ForeignKey objects, this method accepts a bulk argument to control how to perform the operation. If True (the default), QuerySet.update() is used. If bulk=False, the save() method of each individual model instance is called instead. This triggers the :data:~django.db.models.signals.pre_save and :data:~django.db.models.signals.post_save signals and comes at the expense of performance.
