在Twig路径中将对象作为参数传递

Question

When I want to pass parameter via Twig path I write:

<a href="{{ path('blog_post', { id: post.id }) }}">

Is it possible to pass full object eg Post via Twig path?

Thank for help

Answer 1

No, and in my opinion it makes no sense .

How would you want the object to be represented in the url ? 'blog/post/{blog.id:1,blog.author:Foo,blog.title:bar}' ? What if the object change between the time the server display the page (and generate the link)and the time the user clicks on it

Answer 2

It's pretty possible to pass a single numeric id to a controller and get the object instance of that id.

Just specify the type of object of the parameter, like this:

/**
 * @Route("/blog/show/{blog_post}", name="blog-show")
 */
public function showAction(BlogPost $blog_post)
{
    if ($blog_post) {
        var_dump($blog_post)
    }
}
