# To use, just require in environment.rb, like so:
#
# require 'couchrest/support/rails'
class Hash
# Hack so that CouchRest::Document, which descends from Hash,
# doesn't appear to Rails routing as a Hash of options
def self.===(other)
return false if self == Hash && other.is_a?(CouchRest::Document)
super
end
end

# Need this when passing doc to a resourceful route

# Hack so that CouchRest::Document, which descends from Hash,
