無法加載的樹枝模板（Symfony的2.8.8）

Question

所以，我有以下文件夾結構：

按照Symfony的手冊（click here），我應該能夠加載我的樹枝模板，但Symfony的找不到。

任何想法我可能做錯了什麼？謝謝。

代碼我試過我的應用程序的

return $this->render(
     "AppBundle:DisplayForm.html.twig" 
     , array(
      "form" => $form->createView() 
    ); 

    return $this->render(
     "DisplayForm.html.twig" 
     , array(
      "form" => $form->createView() 
     ) 
    ); 

內容/ AppKernel.php

<?php 

use Symfony\Component\HttpKernel\Kernel; 
use Symfony\Component\Config\Loader\LoaderInterface; 

class AppKernel extends Kernel 
{ 
    public function registerBundles() 
    {

Answer 1

因爲你存儲的包裏面的模板，你還必須引用視圖中的目錄 - 在這種情況下，「空」目錄。

AppBundle::DisplayForm.html.twig 

注意該目錄的::。

如果你感動了整個的appbundle /資源/視圖/目錄下的應用程序/資源/視圖/那麼你就可以多引用它們作爲一個普通的子目錄：

引用模板存儲在：

app/Resources/views/   | AcmeDemoBundle/Resources/views 
----------------------------- | ------------------------------- 
index.html.twig    | AcmeDemoBundle::index.html.twig 
Default/subdir/index.html.twig | AcmeDemoBundle:Default:subdir/index.html.twig 
Default/subdir/index.html.twig | AcmeDemoBundle:Default/subdir:index.html.twig 

Answer 2

也許你已經忘記了@符號：

return $this->render(
    "@AppBundle/DisplayForm.html.twig", [ 
     "form" => $form->createView(
    ] 
);
