Instance Method Details

#discard_all ⇒ Object

Discards the records by instantiating each record and calling its Discard::Model#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.

Examples

Person.where(age: 0..18).discard_all

def discard_all
  kept.each(&:discard)
end

#undiscard_all ⇒ Object

Undiscards the records by instantiating each record and calling its Discard::Model#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.

Examples

Person.where(age: 0..18).undiscard_all
