Automatic marshalling with DB access

Rails
1

I have an item which has a hash for one of its fields. When i store it
in the db, i want to do a Marshal.dump of the hash, and similarly, do a
Marshal.load to turn the saved blob back into a hash again.

Is there a way to easily write this into the model, so that it happens
automatically when saving and loading a record?

thanks

Check out ActiveRecord::Base.serialize

class Foo < ActiveRecord::Base
serialize :bar
end
