I'm trying to store the current versions of a nested association so I can roll
back over time, and I can't figure out what's wrong here. Here's my setter and
getter:
def serialize_children
self.children = ActiveSupport::Base64.encode64(Marshal.dump(self.ads))
end
def unserialize_children
Marshal.load(ActiveSupport::Base64.decode64(self.children))
end
This appears to properly encode the data:
>> c = Composition.find(39)
=> #<Composition id: 39, name: "help me", campaign_id: 5, created_at:
"2011-01-10 03:49:08", updated_at: "2011-01-10 16:34:09", position: 1,
children: "", revisable_original_id: nil, revisable_branched_from_id: nil,
revisable_number: 5, revisable_name: nil, revisable_type: nil,
revisable_current_at: nil, revisable_revised_at: "2011-01-10 04:14:46",
revisable_deleted_at: nil, revisable_is_current: true>
>> c.serialize_children
=>

But no matter what I try to unserialize it, I always get an empty array as the
result. Is this because of the association overriding my attempt to set a new
array at the same name? I don't get any errors, but I don't get any data either.
Thanks in advance,
Walter
