我可以成功使用followig代码从控制器发送电子邮件:

$message = \Swift_Message::newInstance()
    ->setSubject('Hello Email')
    ->setFrom('send@example.com')
    ->setTo('recipient@example.com')
    ->setBody($this->renderView('HelloBundle:Hello:email.txt.twig', array('name' => $name)))
;
$this->get('mailer')->send($message);

我如何修改代码以从服务类中使用它？

我想在我的应用程序中实现Observer Pattern(不是php,这就是为什么不使用Symfony的组件).

虽然组件没有使用类来传播或监听事件,但我发现它很奇怪,因为这样可以使用继承来监听整个事件树.

我看不到使用基于名称的听众的单一优势,你能帮我解决一下吗？

HWIOAuthBundle从/ login路由触发此错误:

An exception has been thrown during the rendering of a template ("No resource owner with name 'google'.") in HWIOAuthBundle:Connect:login.html.twig at line 8.

It's even not clear why it complains about 'google' while we are not refering it anywhere, but hooking a facbook connect at the moment. Did anybody meet the same?

我在symfony2中创建一个实体,我将实体设置为createddatetime和updateddatetime,但是当我在控制器中使用setter时,错误发生在这样

FatalErrorException: Error: Call to a member function format() on a non-object in C:\wamp\www\QuickBacklog\vendor\doctrine\dbal\lib\Doctrine\DBAL\Types\DateTimeType.php line 44

这是我的实体代码:

/**
     * Set createdDatetime
     *
     * @param \DateTime $createdDatetime
     * @return Sections
     */
    public function setCreatedDatetime($createdDatetime)
    {
        $this->createdDatetime = $createdDatetime;

        return $this;
    }

    /**
     * Get createdDatetime
     *
     * @return \DateTime 
     */
    public function getCreatedDatetime()
    {
        return $this->createdDatetime;
    }

    /**
     * Set updatedDatetime
     *
     * @param \DateTime $updatedDatetime
     * @return Sections
     */
    public function setUpdatedDatetime($updatedDatetime)
    {
        $this->updatedDatetime = $updatedDatetime;

        return $this;
    }
