Loads the given URL and parse the JSON for a model. If the model is present, the model will updates. If block given, the block will called, when the the model is saved. The model will be passed as an argument to the block.

Parses given value for key in the right format for MotionModel. Currently only Date/Time support needed

Saves the current model. Calls super when block is not given. If block is given, the url method will be needed to call the remote server. The answer of the server will be parsed and stored. If the record is a new one, a POST request will be fired, otherwise a PUT call comes to the server.

When called, the lastSyncAt Column will be set with Time.now (if present)

Wraps the current model with the given JSON. All the fields found in JSON and self.wrapper will be parsed. Returns true, when no error exists
