/**
* NOTE: when the controller argument is a Doctrine entity, Symfony makes an
* automatic database query to fetch it based on the value of the route parameters.
* The '{slug:post}' configuration tells Symfony to use the 'slug' route
* parameter in the database query that fetches the entity of the $post argument.
* This is mostly useful when the route has multiple parameters and the controller
* also has multiple arguments.
* See https://symfony.com/doc/current/doctrine.html#automatically-fetching-objects-entityvalueresolver.

// Symfony's 'dump()' function is an improved version of PHP's 'var_dump()' but
// it's not available in the 'prod' environment to prevent leaking sensitive information.
// It can be used both in PHP files and Twig templates, but it requires to
// have enabled the DebugBundle. Uncomment the following line to see it in action:
//
// dump($post, $this->getUser(), new \DateTime());
//
// The result will be displayed either in the Symfony Profiler or in the stream output.
// See https://symfony.com/doc/current/profiler.html
// See https://symfony.com/doc/current/templates.html#the-dump-twig-utilities
//
// You can also leverage Symfony's 'dd()' function that dumps and
// stops the execution
