tlowrimore / or_scope.rb
Created March 27, 2013 19:39
OR's together provided scopes, returning an ActiveRecord::Relation. This implementation is smart enough to not only handle your _where_ clauses, but it also takes care of your joins! *Note* This is a work in progress, so it has room to grow
module ActiveRecord::OrScope
def self.included(base)
base.send :extend, ClassMethods
end
module ClassMethods
def or_scope(*scopes)
conditions =
scopes
.map { |scope| "(#{scope.where_clauses.map{ |clause| "(#{clause})"}.join(" AND ")})" }

module Palindrome
def self.palindrome?(n)
n == reverse(n)
end
def self.reverse(n)
rs = 0
while n > 0
n, r = n.divmod 10
rs = rs * 10 + r
