Ruby on Rails

Hello Guys,

I am using couch-rest model gem and below is my snippet code.

class S
include CouchRest::Model::Embeddable
property :s1, String
property :s2, String
end

class P < CouchRest::Model::Base
property :name, String
property :xx, [S]
end

p =P.new
p.xx << S.new(s1: "S1 EXISTS")
p.xx << S.new(s2: "S2 EXISTS")
p.save

Now my doubt is when i do p.save "null" get stored in the couchdb, which
I dont want. If i don't use array, then null gets auto deleted , I want
the same feature for the array as well.

Can you please suggest something?
