augmenting Resourceful's Couchdb engine to allow insertion of new records without ID

gistfile1.txt

Couchdb.prototype.post = function (doc, callback) {
  return this.request('post', doc, function (e, res) {
    if (e) return callback(e);
    
    res.status = 201;
    callback(null, res);
  });
};

Couchdb.prototype.save = function (id, doc, callback) {
  var args = Array.prototype.slice.call(arguments, 0);
  var callback = args.pop();
  var doc = args.pop();
  // if there's an ID left in args after popping off the callback and
  // the doc, then we need to PUT, otherwise create a new record thru POST
  if (args.length) {
    return this.put.apply(this, arguments);
  } else {
    return this.post.call(this, doc, callback);
  }
};
