method

delete

v4.0.2 - Show latest stable - Class: ActiveRecord::Associations::CollectionAssociation

delete(*records)

public

Removes records from this association calling before_remove and after_remove callbacks.

This method is abstract in the sense that delete_records has to be provided by descendants. Note this method does not imply the records are actually removed from the database, that depends precisely on delete_records. They are in any case removed from the collection.
