= ModelSet
ModelSet is a array-like class for dealing with sets of ActiveRecord models. ModelSet
stores a list of ids and fetches the models lazily only when necessary. You can also add
conditions in SQL to further limit the set. Currently I support alternate queries using
the Solr search engine through a subclass, but I plan to abstract this out into a "query
engine" class that will support SQL, Solr, Sphinx, and eventually, other query methods
(possibly raw RecordCache hashes and other search engines).
== Usage:
class RobotSet < ModelSet
end
set1 = RobotSet.new([1,2,3,4]) # doesn't fetch the models
set1.each do |model| # fetches all
# do something
end
set2 = RobotSet.new([1,2])
set3 = set1 - set2
set3.ids
# => [3,4]
set3 << Robot.find(5)
set3.ids
# => [3,4,5]
