Symfony 2 CMF: Embed content twig in another admin twig

Question

I have created a twig file in sonata admin, where I want to show the preview of the another twig created using the sonata cms.

I found the use of render method to embed the controller action.

<div class="preview">
                        {{ render(controller('Bundle:Controller:action') }}
</div>

But the action takes an argument $contentDocument

public function Action($contentDocument, Request $request)
{
}

So how do I render this twig inside the preview div, to show a thumbnail to the user. Thank you

您可以将参数作为第二个参数传递给controller（）树枝函数：{{render（controller（'Bundle：Controller：action'，{'contentDocument'：some_instance_of_a_content_document}）}}
