module Discard::Model::ClassMethods
Public Instance Methods
Discards the records by instantiating each record and calling its {#discard} method. Each object's callbacks are executed. Returns the collection of objects that were discarded.
Note: Instantiation, callback execution, and update of each record can be time consuming when you're discarding many records at once. It generates at least one SQL UPDATE
query per record (or possibly more, to enforce your callbacks). If you want to discard many rows quickly, without concern for their associations or callbacks, use update_all(discarded_at: Time.current) instead.

Person.where(age: 0..18).discard_all
# File lib/discard/model.rb, line 42 def discard_all kept.each(&:discard) end
Discards the records by instantiating each record and calling its {#discard!} method. Each object's callbacks are executed. Returns the collection of objects that were discarded.
Note: Instantiation, callback execution, and update of each record can be time consuming when you're discarding many records at once. It generates at least one SQL UPDATE
query per record (or possibly more, to enforce your callbacks). If you want to discard many rows quickly, without concern for their associations or callbacks, use update_all!(discarded_at: Time.current) instead.

Person.where(age: 0..18).discard_all!
# File lib/discard/model.rb, line 61 def discard_all! kept.each(&:discard!) end
Undiscards the records by instantiating each record and calling its {#undiscard} method. Each object's callbacks are executed. Returns the collection of objects that were undiscarded.
Note: Instantiation, callback execution, and update of each record can be time consuming when you're undiscarding many records at once. It generates at least one SQL UPDATE
query per record (or possibly more, to enforce your callbacks). If you want to undiscard many rows quickly, without concern for their associations or callbacks, use update_all(discarded_at: nil) instead.
