Why people should hate me... dynamic method generation in a static configuration file. Whatever, whatever, I do what I want.

gistfile1.js

exports.definition = {
  config: {
    extra_methods: [
      {
        name: 'test',
        url: 'test',
        type: 'get'
      }
    ],
    extendModel: function(Model) {
      if(Model.config.extra_methods) {
        _.each(Model.config.extra_methods, function(extra_method) {
          var extensions = (new Function('return {'+ extra_method.name +': function(options){this.sync("' + extra_method.name + '", this, options);}}'))();
          _.extend(Model.prototype, extensions);
        }
      }
    }
  }
}
