[英]How to render json into a twig in Symfony2
The question is how to pass a json to twig to render a template. 问题是如何将json传递给细枝以渲染模板。 I've tried to pass a json with JsonResponse object but I did not find the way to render the template. 我尝试通过JsonResponse对象传递json,但没有找到渲染模板的方法。

How can I pass a json from the controller to use it in the DataTable (in twig template) but mantaining the render in this controller. 如何从控制器传递json以在DataTable中使用它(在树枝模板中),但要在此控制器中保留渲染。 Please, can you help me? 拜托,你能帮我吗?
I don't understand what you are trying to achieve but you can simply send json encoded and normal data to your twig, to use it how you want 我不明白您要实现的目标,但是您可以简单地将json编码的普通数据发送到树枝,以便按需使用
return $this->render('admin/tarifas/index.html.twig', array(
'tarifas' => $tarifas
'json_tarifas' => json_encode($tarifas)
));
You can render like this, 您可以这样渲染
return $this->render('admin/tarifas/index.html.twig', array(
'tarifas' => $tarifas
'json_tarifas' => json_encode($tarifas)
));
and retrieve like this in twig, 并像树枝一样取回
<script type="text/javascript">
$(document).ready( function () {
$('#tarifas_index').DataTable({
data: $.parseJSON('{{ json_tarifas | raw }}')
});
} );
</script>
