Populate related models fields in QuerySet.bulk_create()

With reference to https://code.djangoproject.com/ticket/27408, is there a way to populate the fields on the related model during bulk_create?
Currently, we have to use a for loop to populate related model fields and then use bulk create which is really slow.

We are using MySql Database so bulk_create does not return id lists so it also can’t be used.

Not on MySQL unfortunately. The lack of support for the RETURNING clause, or any other interface that allows returning the last inserted IDs really, makes it impossible to implement.
