Your YAML file contains serialized ruby objects - the !ruby/
object:LineItem bits indicate that.
In dev mode, constants are removed after requests (this is part of the
reloading of source in dev mode, which is exactly what
config.cache_classes does).
Odds are that when you hit your create action the LineItem and
Contract classes have not yet been loaded. YAML's loading does not
apparently hit const_missing so when it sees a constant (ie Contract)
that does not exist you just get something generic (ie YAML::Object).
In production mode classes are never cleared out like this so unless
the server is serving its very first request odds are the Contract
class is loaded so you get back an instance of Contract. YAML::Object
has an ivars method that gets you something like a hash of instance
variables, but other objects don't (everyone has instance_variable_get
though, but that's not very nice)
It is the dev mode behavious which is weird, you can work around it by
using require_dependency to load contract, line_item and whatever else
you need. Personally I wouldn't store the active record objects
themselves - just their hash of attributes.
