generateUrl问题

Question

我正在尝试生成一个网址,但即使它有效,我仍然会收到一个奇怪的警告.我正在制作一个api xml页面,我在控制器中使用以下调用:

public function executeList(sfWebRequest $request)
{
    $this->users = array();
    foreach($this->getRoute()->getObjects() as $user)
    {
        $this->users[$this->generateUrl('user_show', $user, true)] = $user->asArray($request->getHost());
    }
}

user_show路由如下:

# api urls
user_show:
  url:   /user/:nickname
  param: { module: user, action: show }

并且xml输出如下:

<br />
<b>Warning</b>:  array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br />
<br />

<br />
<b>Warning</b>:  array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br />
<?xml version="1.0" encoding="utf-8"?>
<users>
  <user url="http://krowdd.dev/frontend_dev.php/user/danny">
    <name>Danny tz</name>
    <nickname>danny</nickname>
    <email>comedy9@gmail.com</email>
    <image></image>
  </user>
  <user url="http://krowdd.dev/frontend_dev.php/user/adrian">
    <name>Adrian Sooian</name>
    <nickname>adrian</nickname>
  </user>
</users>

所以它输出正确的xml,但我不知道为什么它在调用generateurl方法时抛出警告.

谢谢!

这是generateUrl的签名:

public function generateUrl($route, $params = array(), $absolute = false)

特别注意第二个参数.在常规路线的情况下,它应该是一个数组,但是:如果您的路线是sfPropelRoute或其等同的学说,它可以是一个对象.
我相信你会得到这些错误,因为路线没有被定义为sfPropelRoute(或学说).
