@Template
=========
Usage
-----
The ``@Template`` annotation associates a controller with a template name::
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
/**
* @Template("SensioBlogBundle:Post:show.html.twig")
*/
public function showAction($id)
{
// get the Post
$post = ...;
return array('post' => $post);
}
When using the ``@Template`` annotation, the controller should return an
array of parameters to pass to the view instead of a ``Response`` object.
.. note::
If you want to stream your template, you can make it with the following configuration::
/**
* @Template(isStreamable=true)
*/
public function showAction($id)
{
// ...
}
.. tip::
If the action returns a ``Response`` object, the ``@Template``
annotation is simply ignored.
If the template is named after the controller and action names, which is the
case for the above example, you can even omit the annotation value::
/**
* @Template
*/
public function showAction($id)
{
// get the Post
$post = ...;
return array('post' => $post);
}
.. note::
If you are using PHP as a templating system, you need to make it
explicit::
/**
* @Template(engine="php")
*/
public function showAction($id)
{
// ...
}
And if the only parameters to pass to the template are method arguments, you
can use the ``vars`` attribute instead of returning an array. This is very
useful in combination with the ``@ParamConverter`` :doc:`annotation
<converters>`::
/**
* @ParamConverter("post", class="SensioBlogBundle:Post")
* @Template("SensioBlogBundle:Post:show.html.twig", vars={"post"})
*/
public function showAction(Post $post)
{
}
which, thanks to conventions, is equivalent to the following configuration::
/**
* @Template(vars={"post"})
*/
public function showAction(Post $post)
{
}
You can make it even more concise as all method arguments are automatically
passed to the template if the method returns ``null`` and no ``vars``
attribute is defined::
/**
* @Template
*/
public function showAction(Post $post)
{
}
