Loopback REST connector, data mapping response to model?

Question

I've setup a simple "product" model (ie {id:"string","name":string, etc}) and setup a datasource using the REST connector to a remote URL that returns a JSON blob containing dozens of fields, how do I go about mapping the fields from the remote response to my local model? Whenever I execute my method I'm getting back the raw response from the remote....I was expecting, at a minimum, to get back an empty version of my model.

I'm pretty sure you will have to override the find() method on your model and perform this mapping work manually.

Something like this:

module.exports = function(app) {
  var Product = app.models.Product;
  var find = Product.find;

  Product.find = function(filter, cb) {
      // invoke the default method
      find.call(Product, function(err, original_results) {
          var results = {};     // a placeholder for your expected results

          results.name = original_results.id;
          results.name = original_results.name;
          results.description = original_results.long_description;
          // and so on    

          cb(null, results)
      });
  }
}
