Module: Hoodoo::ActiveRecord::Finder

Defined in:
lib/hoodoo/active/active_record/finder.rb,
lib/hoodoo/active/active_record/search_helper.rb

Overview

Mixin for models subclassed from ActiveRecord::Base providing support methods to handle common show and list filtering actions based on inbound data and create instances in a request context aware fashion.

It is STRONGLY RECOMMENDED that you use the likes of:

  • Hoodoo::ActiveRecord::Finder::ClassMethods#acquire_in

  • Hoodoo::ActiveRecord::Finder::ClassMethods#list_in

…to retrieve model data related to resource instances and participate “for free” in whatever plug-in ActiveRecord modules are mixed into the model classes, such as Hoodoo::ActiveRecord::Secure.

See also:

Dependency Hoodoo::ActiveRecord::Secure is included automatically.

  unless model == Hoodoo::ActiveRecord::Base

  super( model )
end

.instantiate(model) ⇒ Object

When instantiated in an ActiveRecord::Base subclass, all of the Hoodoo::ActiveRecord::Finder::ClassMethods methods are defined as class methods on the including class.

This module depends upon Hoodoo::ActiveRecord::Secure, so that will be auto-included first if it isn’t already.
