.dump(schedule) ⇒ Object

This should normally receive a Schedule object. In some unknown circumstance that I can’t reproduce, it would save an already-dumped serialized YAML Schedule string into a YAML string wrapper, effectively double-bagging the YAML. I only assume it receives a String when loading a bad YAML value from the database, which then propagates and re-re-serializes itself into YAML on every save.

def self.dump(schedule)
  case schedule
  when IceCube::Schedule then schedule.to_yaml
  when String            then schedule
  end
end

.load(yaml) ⇒ Object

Only load YAML serializations that are present, not empty strings An invalid value can raise an error that gets caught by ActiveRecord and results in the original string getting passed through. This allows it to be saved back unchanged if necessary.
