The point of this module is to avoid the StaleObjectError raised when lock_version is implemented in ActiveRecord. We accomplish this by using a “priority record”. Meaning this record is used if possible, it gets priority. This way we don't save a record behind the scenes thus making an object being used stale.
# File lib/authlogic/session/priority_record.rb, line 7 def self.included(klass) klass.class_eval do attr_accessor :priority_record end end
Setting priority record if it is passed. The only way it can be passed is through an array:
session.credentials = [real_user_object, priority_user_object]
# File lib/authlogic/session/priority_record.rb, line 16 def credentials=(value) super values = value.is_a?(Array) ? value : [value] self.priority_record = values[1] if values[1].class < ::ActiveRecord::Base end
# File lib/authlogic/session/priority_record.rb, line 23 def attempted_record=(value) value = priority_record if value == priority_record super end
# File lib/authlogic/session/priority_record.rb, line 28 def save_record(alternate_record = nil) r = alternate_record || record super if r != priority_record end
