require 'active_support/option_merger'
class Object
# An elegant way to factor duplication out of options passed to a series of
# method calls. Each method called in the block, with the block variable as
# the receiver, will have its options merged with the default +options+ hash
# provided. Each method called on the block variable must take an options
# hash as its final argument.
#
# with_options :order => 'created_at', :class_name => 'Comment' do |post|
# post.has_many :comments, :conditions => ['approved = ?', true], :dependent => :delete_all
# post.has_many :unapproved_comments, :conditions => ['approved = ?', false]
# post.has_many :all_comments
# end
#
# Can also be used with an explicit receiver:
#
# map.with_options :controller => "people" do |people|
# people.connect "/people", :action => "index"
# people.connect "/people/:id", :action => "show"
# end
#
