Any suggestions on how to extract the database stuff. Is this fine since it's just an adapter?

UserControllers.js

module.exports = {

  find: function (req, res) {
    return User.findOne(req.param('id'))
      .exec(function(err, user) {
        return res.json({
          user: user
        });
      });
  },

  index: function (req, res) {
    return User.find()
      .exec(function(err, users) {
        return res.json({
          users: users
        });
      });
  },

  _config: {

  }

};
