self.destroy_all(conditions = nil) — ActiveRecord::Base

self.destroy_all(conditions = nil)

Destroys the records matching conditions by instantiating each record and calling their destroy method. This means at least 2*N database queries to destroy N records, so avoid destroy_all if you are deleting many records. If you want to simply delete records without worrying about dependent associations or callbacks, use the much faster delete_all method instead.

Parameters

conditions - Conditions are specified the same way as with find method.

Example

Person.destroy_all("last_login < '2004-04-04'")

This loads and destroys each person one by one, including its dependent associations and before_ and after_destroy callbacks.

conditions can be anything that find also accepts:

Person.destroy_all(:last_login => 6.hours.ago)

Parameters

conditions opt = nil
