hello, please give me snipped, that reconstruct ActiveRecord object from  
YAML or Marshal.dump. When i type for example: YAML::load(item.to\_yaml),  
the returned object is not (item’s class) Item. When i use:  
Marshal::load(Marshal::dump item), it throws exception “undefined  
class/module Item” How can I do this? Thanx.

At a guess, a model’s attributes member is very Hash-like, and Hashes  
are also a native YAML type. So you _might_ store it with yaml\_string  
= model.attributes.to\_yaml , and load that with model.attributes =  
YAML::load(yaml\_string).
