[TYPO3-mvc] Standalone Controller

[Sebastian Michaelsen]

Hey *,

from time to time I came accross situations where I wanted to use 
Controllers, Actions, Persistence etc NOT in a context of rendering a 
Frontend-Plugin or Backend-Module.
But I found it hard to invoke Extbase within a UserFunc or through a 
request coming from CLI.

I there a good standard way to do this?

For my usage I implemented a StandaloneController that can be extended 
by any controller and that provides some basic Extbase functionality:

- Call an Action (no Argument validation or mapping)
- Render the view implicitly
- Take care of persistence

Usage:
$controller = 
$objectManager->get('Me\\MyProject\\Controller\\MyController'); // 
MyController extends the StandaloneController
$controller->setTemplatePath('somePath/to/fluidTemplates/');
return $controller->callAction('index');

So if there is no good standard way to do this and if anyone else needs 
such functionality, here's my controller (tested with 6.0 master):

namespace Me\MyProject\Controller\Generic;

abstract class StandaloneController {

	/**
	 * @var \TYPO3\CMS\Extbase\Persistence\Generic\Manager
	 * @inject
	 */
	protected $persistenceManager;

	/**
	 * @var \TYPO3\CMS\Extbase\Object\ObjectManager
	 * @inject
	 */
	protected $objectManager;

	/**
	 * @var \TYPO3\CMS\Fluid\View\StandaloneView
	 * @inject
	 */
	protected $view;

	/**
	 * @var string
	 */
	protected $templatePath;

	/**
	 * @var string
	 */
	protected $format = 'html';

	/**
	 * @param string $format
	 */
	public function setFormat($format) {
		$this->format = $format;
	}

	/**
	 * @param $path
	 */
	public function setTemplatePath($path) {
		$this->templatePath = rtrim($path, '/') . '/';
	}

	/**
	 * @param string $action
	 * @return string
	 * @throws \Exception
	 */
	public function callAction($action) {
		$arguments = func_get_args();
			// remove first argument, it's already assigned to $action
		array_shift($arguments);
		if(method_exists($this, $action . 'Action')) {
			$this->view->setFormat($this->format);
			$this->view->setTemplatePathAndFilename($this->templatePath . $action 
. '.' . $this->format);
			$content = call_user_func_array(array($this, $action . 'Action'), 
$arguments);
			if(!isset($content)) {
				$content = $this->view->render();
			}
			$this->persistenceManager->persistAll();
			return $content;
		} else {
			throw new \Exception('Action does not exist', 1347054560);
		}
	}

}
