Callbacks

MarkMapper makes use of the ActiveModel::Callbacks, so they are identical to Rails.

The callbacks supported are the same as on ActiveModel, the callbacks provided are:

• before_validation
• after_validation
• before_save
• after_save
• before_create
• after_create
• before_update
• after_update
• before_destroy
• after_destroy

For embedded documents you have similar callbacks:

• before_validation
• after_validation
• before_save
• after_save
• before_create
• after_create
• before_update
• after_update
• before_destroy
• after_destroy

Example

The callbacks are set on your model like this:

class Monkey
  include MarkMapper::Document
  before_save :do_something_before_save

  private
  def do_something_before_save
  end
end
