class Contact < ActiveRecord::Base after_save { logger.info( 'New contact saved!' ) } end
2Notes
Return True
As is the case with the before_validation and before_save callbacks, returning false will break the callback chain. For example, the expire_cache_id method will not run if Rails.cache.expire returns false (as it will if the key is not cached with memcache).
=== Returning False Example (Bad)
after_save :expire_cache_by_name
after_save :expire_cache_by_id
def expire_cache_by_name
Rails.cache.expire("my_object:name:#{self.name}")
end
def expire_cache_by_id
Rails.cache.expire("my_object:#{self.id}")
end
=== Returning True Example (Good)
def expire_cache_by_name
Rails.cache.expire("my_object:name:#{self.name}")
return true
end
def expire_cache_by_id
Rails.cache.expire("my_object:#{self.id}")
return true
end
gives a parameter
As a note, you can use it like this:
after_save {|instance|
}
it will pass in the instance being saved.
