Rails - Jan 2007 - Weirdness when save symbols to AR string fields

I have a model foo with two fields: id and string. When I try to save a
symbol into that string field I get weird results:
>> foo = Foo.new(:string => :foobar)
>> foo.string
=> :foobar
>> foo.save
>> foo.string
=> :foobar
>> foo = Foo.find(foo.id)
=> #<Foo:0x467282c @attributes={"id"=>5,
"string"=>"--- :foobar\n"}>
>> foo.string
=> "--- :foobar\n"

Apparently the database save is converting the symbol into YAML. But I
don''t know why and I can''t seem to unmarshal it. Any idea
what''s going
on?

Thanks!

Yea, it serializes non-db fields to yaml.  Use the serialize method to
unserialize it for you.
