Module: ActsAsTaggableOnMongoid::Models::Concerns::TagHooks

Extended by:

ActiveSupport::Concern

Defined in:

lib/acts_as_taggable_on_mongoid/models/concerns/tag_hooks.rb

Overview

Update and Destroy hooks for tags to update denormalized data.

NOTE: If the tag is cached AND owned, assumptions are made about the

relationship of a Tag to the Taggings and the taggable_type.

Specifically, the taggable_type is assumed to have an ID field that
matches the owner.  This field can be specified in the tag_definition
as owner_id_field.

If there isn't a simple relationship like this then override the following
methods to update the cached data properly:
 * remove_cached_taggings
 * update_cached_taggings
