Rails - Nov 2006 - Serializing - Deserializing a data structure in RoR

Hi. I have a data structure, with arrays and hashes, with several data types
inside. For instance:

{
   :conditions => [ ''stand_id = ?'' , 1],
   :limit => 10,
   :offset => 10
}

I want to serialize this structure in a string, to be stored , then another
day in other session I would like to restore it exactly as it is, for
instance symbols remain symbols, arrays remain arrays, hashes remain hashes
and so on for other data types. How can I do that in Ruby / RoR?

Thanks, Vinicius

Serializing is called ''Marshalling'' in Ruby.

Marshalling is not at all difficult in Ruby, check for example
http://ruby-doc.org/core/classes/Marshal.html
http://phrogz.net/ProgrammingRuby/ref_m_marshal.html

You could also use YAML to do the same, see
http://ruby-doc.org/core/classes/YAML.html

Let''s say you want to put this in myobject.foo.

myobject.foo = s.to_yaml

Pretty easy.

Now you''ve retrieved myobject from the database and you want to load s
with the stuff that''s serialized in foo.

s = YAML::load(myobject.foo)
