Smart Controller

Based on the article Symfony 4: Creating Smart Controller. Summary:

• Before render method - allows you to set parameters you always need
• Template parameters - can be set from multiple places easily
• Usefull methods - getRequest(), getRootDirectory(), getTemplateParameter()

Installation

composer require machy8/smart-controller

Example

Symfony original lucky controller example.

class LuckyController extends AbstractController
{

	/**
	 * @Route("/lucky/number")
	 */
	public function number(): Response
	{
		return $this->render('lucky/number.twig', [
			'number' => random_int(0, 100),
		]);
	}


	/**
	 * @Route("/unlucky/number")
	 */
	public function unluckyNumber(): Response
	{
		return $this->render('lucky/number.twig', [
			'number' => random_int(0, 100),
		]);
	}

}

and now with the Smart Controller.

class LuckyController extends SmartController
{

 public function beforeRender(): void
 {
 $this->setTemplateParameters([
 'number' => random_int(0, 100)
 ]);
 }

 /**
 * @Route("/lucky/number")
 */
 public function renderLuckyNumber(): Response
 {
 return $this->renderTemplate('lucky/number.twig');
 }

 /**
 * @Route("/unlucky/number")
 */
 public function renderUnluckyNumber(): Response
 {
 return $this->renderTemplate('lucky/number.twig');
 }

}
