使用ParamConverter和POST动作的Symfony

Question

I'm building rest API, and have method to save posts.

postPostAction(Request $request)
{

}

my POST request contains all Entity/Post properties

How to use ParamConverter to have Entity/Post in this method parameters like:

postPostAction(Post $post)
{

}

Do I need create custom ParamConverter, or it make sense using ParamConverter only with PUT and GET ?

Answer 1

You can use default paramConverter like this

use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;

/**
 * @ParamConverter("thePost", class = "AppBundle:Post")
 */
public function postPostAction(Post $thePost)
{
    // ...
}

The annotation takes several parameters, there the name of the variable to convert and the class to convert to.

You could even omit the annotation and write

public function postPostAction(Post $thePost)
{
    // ...
}

this would automatically convert your variable to an entity.

You can find more informations in the documentation.
