Callbacks

Dynamoid also employs ActiveModel callbacks. Right now the following callbacks are supported:

• save (before, after, around)
• create (before, after, around)
• update (before, after, around)
• validation (before, after)
• destroy (before, after, around)
• after_touch
• after_initialize
• after_find

Example:

class User
  include Dynamoid::Document

  # ...

  before_save :set_default_password
  after_create :notify_friends
  after_destroy :delete_addresses
end
