title: Using routes to generate URLs in a Symfony task
body: <p>I am running <a href="http://en.wikipedia.org/wiki/Symfony" rel="noreferrer">Symfony</a> 1.3.6 on Ubuntu 10.0.4 LTS.</p>
  
  <p>I have written a Symfony task that generates a report which contains links (URLs).</p>
  
  <p>Here is a snippet of the <code>execute()</code> method in my task class:</p>
  
  <pre><code>  protected function execute($arguments = array(), $options = array())
    {
      //create a context
      sfContext::createInstance($this-&gt;configuration);
      sfContext::getInstance()-&gt;getConfiguration()-&gt;loadHelpers(array('Url', 'Asset', 'Tag'));
  
      ...
      $url = url_for("@foobar?cow=marymoo&amp;id=42");
  
      // Line 1
      echo '&lt;a href="'.$url.'"&gt;This is a test&lt;/a&gt;';
  
      // Line 2
      echo link_to('This is a test', $url); 
    }
  </code></pre>
  
  <p>The route name is defined like this:</p>
  
  <pre><code>foobar:
    url: /some/fancy/path/:cow/:id/hello.html
    param: {  module: mymodule, action: myaction }
  </code></pre>
  
  <p>When this is run, the generated link is:</p>
  
  <p><strong>Line 1</strong> produces this output:</p>
  
  <blockquote>
    <p>./symfony/symfony/some/fancy/path/marymoo/42/hello.html</p>
  </blockquote>
  
  <p>instead of the expected:</p>
  
  <blockquote>
    <p>/some/fancy/path/marymoo/42/hello.html</p>
  </blockquote>
  
  <p><strong>Line 2</strong> generates an error:</p>
  
  <blockquote>
    <p>Unable to find a matching route to
    generate url for params "array ( 
    'action' => 'symfony',  'module' =>
    '.',)".</p>
  </blockquote>
  
  <p>Again, the expected URL is:</p>
  
  <blockquote>
    <p>/some/fancy/path/marymoo/42/hello.html</p>
  </blockquote>
  
  <p>How may I resolve this?</p>
