Formaters

At query level

User.dataTables({
  limit: 20,
  formatter: function(user) {
    return {
      name: user.first_name + ' ' + user.last_name
    }
  }
})

At schema level

UserSchema.plugin(dataTables, {
  formatters: {
    toPublic : function (user) {
      return {
        name: user.first_name + ' ' + user.last_name
      }
    }
  }
});

Use by doing this at query level

User.dataTables({
  limit: 20,
  formatter: 'toPublic',
})

Note: if you use formatters you get an array of objects on data, instead of the model instance.
