Used to serialize CakePHP Errors and Exceptions, primarily as HTML, JSON or JSON API.

Adds two new Exception Classes to extend from to get JSON API formatted error messages.

Requirements

  • CakePHP 2.3+
  • PHP 5.4+

Installation

Composer

$ composer require loadsys/cakephp-serializers-errors:~1.0

Usage

  • Add this plugin to your application by adding this line to your bootstrap.php
CakePlugin::load('SerializersErrors', array('bootstrap' => true));
  • Update your core.php to use the plugin's ExceptionRenderer in place of the core's
Configure::write('Exception', array(
	'handler' => 'ErrorHandler::handleException',
	'renderer' => 'SerializersErrors.SerializerExceptionRenderer',
	'log' => true,
));
  • Once this is done Exceptions are rendered as possible, JSON API errors, JSON formated errors or standard HTML responses, differing on the request Accepts Header.
  • So if you use:
  • Accepts: application/vnd.api+json JSON API Errors are returned
  • Accepts: application/json JSON Errors are returned
  • Accepts: */* Normal CakePHP HTML Style Errors are returned
  • If you build custom Exceptions that extend BaseSerializerException you get Exceptions that enable the full feature set of JSON API errors in addition to be rendering in the pattern described above.

Sample Responses

Here are some sample response for the different Exception classes.
