For my model I want to have an enumeration as a datatype, but I don't know how to do that. I couldn't find anything helpful in the documentation from geddyjs.org or with google.

A model could be defined like this:

var fooModel= function () {

  this.defineProperties({

    fooField: {type: 'datatype'},

    .............................

   });

}

Where and how should I define the enumeration and how do I use it?
