如何在树枝模板中从symfony2路由名称生成URL？

Question

I want to avoid hard-coding relative URLs in my twig templates in a Symfony2 project.

I have defined some route names in my controllers, for example:

@Route("/", name="homepage")

Is there a Twig or Symfony2 function that could help me generate links properly? Something like:

<a href='{{ magic_fct("homepage") }}'>Home</a>

would return:

<a href='/'>Home</a>

Answer 1

使用以下内容：

<a href='{{ path('homepage') }}'>Home page</a>

Answer 2

Yes, of course you can. Take a look in Linking to Pages documentation.

<a href="{{ path('homepage') }}">Home</a>
