Destroying a non-permanent record with permanent record associations?

[aried3r]

I have a model A which is non permanent which has_many :bs, dependent: :destroy. There is also a foreign key on B, called a_id, so I have referential integrity.

Now, of course, if I try to destroy an instance of A, this crashes, because my permanent B still exists when .destroy is called on it.

--- Caused by: ---
PG::ForeignKeyViolation:
  ERROR:  update or delete on table "A" violates foreign key constraint "fk_rails_feff868667" on table "B"
  DETAIL:  Key (id)=(589) is still referenced from table "B".

Is there a way to propagate the :force option down to the Bs? I know this is a very specific use case since I don't want to remove the referential integrity and indeed want to delete the otherwise permanent Bs, when I delete an A.

But since I saw that the reverse case, if A was permanent and B wasn't, is covered by this gem and documented in the specs, I thought I might ask. I didn't dig deep enough into the code yet to see if this is possible to achieve.
