问题是如何将json传递给twig以呈现模板。我试图传递一个json与JsonResponse对象,但我没有找到方式来呈现模板。

我如何从控制器传递json在DataTable中使用它(在twig模板中),但在此控制器中维护渲染。你能帮帮我吗?
你可以这样呈现
return $this->render('admin/tarifas/index.html.twig', array(
'tarifas' => $tarifas
'json_tarifas' => json_encode($tarifas)
));
和检索像这样在树枝,
<script type="text/javascript">
$(document).ready( function () {
$('#tarifas_index').DataTable({
data: $.parseJSON('{{ json_tarifas | raw }}')
});
} );
</script>
我不明白你想要实现什么,但你可以简单地将json编码和正常数据发送到你的小枝,以你想要的方式使用它
return $this->render('admin/tarifas/index.html.twig', array(
'tarifas' => $tarifas
'json_tarifas' => json_encode($tarifas)
));
