How do I serialize/de-serialize data with embedded documents?

[dblock]

I'm trying to write an export/import for data with Rake, currently
using to_json and from_json.

I see two problems when doing this:

object = model.new.from_json line
object.save!

1) If the object already exists in the database, MongoID tries to
insert a dup. How do I update this data?
2) I am missing embedded documents. Is there a way to serialize the
entire thing?

Thx

Please ignore 2), my mistake.

Try:

object = Model.instantiate(json_as_a_hash)
object.save!
