Rails - Jul 2005 - Marshaling model-objects wont save id property

Hi

When i try to serialize an ActiveRecord object it doesn''t save the
id-property of the modell.

class ModelA < ActiveRecord
  :serialize model_b
end

model_b_obj = ModelB.find(1)
model_a = ModelA.new
model_a.model_b = model_b_obj
model_a.save

model_a.model_b.id -> ""

I assume it has something to do with visibility of class ModelA... Do I
have to override some properties from ActiveRecord?

Thanks!

Does model.save return true or false?
After attempting to save, what does model.errors.full_messages give you?

it results true. 

In the database the row is stored something like:

 id | document_id | user_id | content_id |           data            |
instance_id
----+-------------+---------+------------+---------------------------+-------------
 28 |          20 |       2 |          1 | --- !ruby/object:Article
attributes:
  name: bajs
  preamble: lök
  text: lökölk
  url: "ölkölk"
new_record: true |          20

What I am missing in the YAML-representation is the attribute "id".
