#remove_items(plan_id, ids) ⇒ Object

This method deletes beneficiary round plan items based on the selection of the user in a given round.

Params:

plan_id => The id of the round plan.
ids => A list of beneficiary round plan item ids to delete.

When deleting the selected beneficiary round plan items, if the corresponding round plan item becomes empty, then it too should be deleted.

Raises:

  • (StandardError)
