static_active_record_context.rb

StaticActiveRecordContext

Simple module to extends technoweenie‘s rad ActiveRecordContext plugin svn.techno-weenie.net/projects/plugins/active_record_context/ to permanently cache active record data for the life of the class

As with active_record_context, only finds based on ids are cache hits, however id finders are the majority of calls from associations. If cache hits on fields and methods are needed, refer to acts_as_static_record

 class TelephoneCarriers < ActiveRecord::Base
   extend StaticActiveRecordContext
   has_many :phone_numbers
 end

The following would exercise a cache hit

 phone_number.telephone_carrier

The static cache is available both inside and outside with_context block, where as the cache for typical records the context is only with the block.

 PhoneNumber.with_context {
   PhoneNumber.find :all
   TelephoneCarriers.find :all
 }

 phone = PhoneNumber.find_by_id(1)             # not a cache hit
 phone.telephone_carrier                       # cache hit
 telephone_carrier = TelephoneCarrier.find(1)  # cache hit
