to_hash result for photo cannot be saved in mongoid

[sufleR]

When I try to save hash representation of returned photo I get error:

  photo = flickr.photos.getInfo(photo_id: photo_id, secret: secret)
  photo_hash= photo.to_hash
  photo_hash_.class
  => Hash
  photo_hash.class.class
  => Class
  photo_hash.to_bson
  #NoMethodError: undefined method `bson_type' for #<FlickRaw::Response:0x0000010d4ab9c0>
  #from ....gems/ruby-2.1.1@..../gems/bson-2.3.0/lib/bson/hash.rb:44:in `block (2 levels) in to_bson'

posiible workaround for this:

   JSON.parse(photo.to_json).to_bson
   #bson result.

Is there any other solution to save this hash in mongodb properly?

The Flickraw objects don't have the bson serialization methods so you have to add them yourself.
