Generate CRUD from sequelize models (missing validators, auth, etc... just for the idea)

fish.js

  var Fish = sequelize.define('Fish', {
    scientificName: DataTypes.STRING,
    bio: DataTypes.TEXT
  }, {
    classMethods: {
      /*associate: function(models) {
        // associations can be defined here
      },*/
      rest: {
        path: 'fishes',
        creationProperties: ['scientificName', 'bio']
      }
    }
  });
  return Fish;
};
