无法获取在Symfony2项目中正常工作的表单

我正在为我正在进行的一个项目建立一个良好的联系方式。我一直在学习本教程，起初我修改了部分教程以适应我的项目。因此，在我的Contactform.php文件中，即教程中的Task.php文件中，我的代码如下所示：

namespace Shout\MainBundle\Entity;

班级联络表 { 保护$yourname

protected $youremail;

protected $yourphone;

protected $yourenquiry; 

protected $newsletter;

protected $events;

public function getYourname()
{
    return $this->yourname;
}
public function setYourname($yourname)
{
    $this->yourname = $yourname;
}

public function getYouremail()
{
    return $this->youremail;
}
public function setYouremail($youremail)
{
    $this->youremail = $youremail;
}

public function getYourphone()
{
    return $this->yourphone;
}
public function setYourphone($yourphone)
{
    $this->yourphone = $yourphone;
}

public function getYourenquiry()
{
    return $this->yourenquiry;
}
public function setYourenquiry($yourenquiry)
{
    $this->YourEnquiry = $yourenquiry;
}

public function getNewsletter()
{
    return $this->newsletter;
}
public function setNewsletter($newsletter)
{
    $this->newsletter = $newsletter;
}

public function getEvents()
{
    return $this->events;
}
public function setEvents($events)
{
    $this->events = $events;
}

在处理联系人表单呈现的DefaultClasses.php文件中，我有以下代码：

    public function contactAction(Request $request)
{

    $contactform = new Contactform();

    $form = $this->createFormBuilder($contactform)
        ->add('yourname', 'text')
        ->add('youremail', 'text')
        ->add('yourphone', 'text')
        ->add('yourenquiry', 'text')
        ->add('newsletter', 'text')
        ->add('events', 'text')
        ->getForm();

    return $this->render('ShoutMainBundle:Default:contact.html.twig', array('form' => $form->createView()));

}

显然，这与教程不同，因为我不想用数据预填充它

然后，在contact.php.twig文件中，我有以下代码调用联系人表单：

                    <form action="{{ path('form_contact') }}" method="post" {{ form_enctype(cform) }}>
                    {{ form_widget(cform) }}

                    <input type="submit" />
                </form>

问题是，操作部分试图找到一个不存在的页面。我删除了该页面，它成功了。现在将创建一个页面供其引用

    ShoutMainBundle_mainpage:
    pattern:  /mainpage/{slug}
    defaults: { _controller: ShoutMainBundle:Default:mainpage }
ShoutMainBundle_subpage:
    pattern:  /mainpage/{page}/{slug}
    defaults: { _controller: ShoutMainBundle:Default:subpage }
ShoutMainBundle_news:
    pattern:  /news
    defaults: { _controller: ShoutMainBundle:News:index }
ShoutMainBundle_newsarticle:
    pattern:  /news/article/{article}
    defaults: { _controller: ShoutMainBundle:News:article }
ShoutMainBundle_event:
    pattern:  /event
    defaults: { _controller: ShoutMainBundle:Event:index }
ShoutMainBundle_eventselected:
    pattern:  /event/{id}/{event}
    defaults: { _controller: ShoutMainBundle:Event:selected }
ShoutMainBundle_blog:
    pattern:  /blog
    defaults: { _controller: ShoutMainBundle:Blog:index }
ShoutMainBundle_blogarticle:
    pattern:  /blog/article/{article}
    defaults: { _controller: ShoutMainBundle:Blog:article }
ShoutMainBundle_blogcategorieshome:
    pattern:  /blog/categories/
    defaults: { _controller: ShoutMainBundle:Blog:categoryhome }
ShoutMainBundle_blogcategoriesselected:
    pattern:  /blog/category/{category}
    defaults: { _controller: ShoutMainBundle:Blog:categoryselected }
ShoutMainBundle_blogarchive:
    pattern:  /blog/archive/{category}
    defaults: { _controller: ShoutMainBundle:Blog:archive }
ShoutMainBundle_contact:
    pattern:  /contact-us
    defaults: { _controller: ShoutMainBundle:Default:contact }
