Weirdness when save symbols to AR string fields

Rails
1

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.
