Creating validation check in beforeCreate hook

I have a user model which I would like to add some additional validation too.

I am using the beforeCreate hook to do my checks, but I am having some trouble figuring out what to do after that.

beforeCreate: function(values, callback) {

    UserService.additionalCheck(values, function(err, success){
        if(err){
            return callback(err);
        }
        if(success === true){
            callback();
        }
        else{
            return callback('Did not validate');
        }
    });
}

The problem is that this results in a 500 status and Error (E_UNKNOWN) :: Encountered an unexpected error.

All I want to do is send the same kind of response that you get when you have an 'invalidAttribute', how can I accomplish this?

TLDR: How can I make my own invalid attribute checks and responses?

Sails documentation covers custom validation on attributes here. The example below pulls from that documentation. Using the custom validations would mean you don't need to use a beforeCreate hook.

// api/models/foo
module.exports = {

  types: {
    is_point: function(geoLocation) {
      return geoLocation.x && geoLocation.y
    },
    password: function(password) {
      return password === this.passwordConfirmation;
    }
  },
  attributes: {
    firstName: {
      type: 'string',
      required: true,
      minLength: 5,
      maxLength: 15
    },
    location: {
      //note, that the base type (json) still has to be defined
      type: 'json',
      is_point: true
    },
    password: {
      type: 'string',
      password: true
    },
        passwordConfirmation: {
          type: 'string'
    }

  }
}

If you'd also like custom validation messaging, as well as a few Rails like findOrCreate type class methods you can use the Sails Hook Validation package. Note that it requires Sails 0.11.0+.
