Caching 从Symfony 1.4中的批处理文件访问缓存

我正在尝试从Symfony 1.4中的批处理文件访问缓存

//lib/batch/test.php
require_once(dirname(__FILE__).'/../../config/ProjectConfiguration.class.php');
$configuration = ProjectConfiguration::getApplicationConfiguration('frontend', 'dev', true);

// first try
$filecache = new sfFileCache(array(
 'cache_dir' => sfConfig::get('sf_template_cache_dir'), 
 'automatic_cleaning_factor' => 0, 
 'prefix' => '/Library/WebServer/Documents/mywebsite/apps/frontend/template'));

$cache = new sfViewCacheManager(sfContext::createInstance($configuration), $filecache);

//always false
var_dump($cache->has('chart/index'));

//second try
$class = sfConfig::get('sf_factory_view_cache', 'sfFileCache');
$filecache = new $class(sfConfig::get('sf_factory_view_cache_parameters', array (
 'automatic_cleaning_factor' => 0,
 'cache_dir' => '/Library/WebServer/Documents/mywebsite/cache/frontend/dev/template',
 'lifetime' => 86400,
 'prefix' => '/Library/WebServer/Documents/mywebsite/apps/frontend/template',
)));

$cache = new sfViewCacheManager(sfContext::createInstance($configuration), $filecache, array (
 'cache_key_use_vary_headers' => true,
 'cache_key_use_host_name' => true,
));


//always false
var_dump($cache->has('chart/index'));

通过模块/操作访问缓存的结果不同（在相同的开发环境中）

我比较了两个缓存对象（批处理与模块/操作），它们完全相同

有什么想法吗

多谢各位

public function executeTest()
{
 $cache = $this->getContext()->getViewCacheManager();

 //always true
 var_dump($cache->has('chart/index'));

 return sfView::NONE;
}
