symfony - symfony 形式的问题

Question

我有以下路线:

blog_show:
    path:      /test/123
    defaults:  { _controller: TotalcanBravofillBundle:Test:test }

而这个 Controller :

    public function testAction()
    {
        $form = $this->createForm(new TestType(), new Test());

        return $this->render('TotalcanBravofillBundle:Test:test.html.twig', array(
            'form' => $form->createView(),
       ));
    }

我有这个实体:

...
class Test
{
/**
     * @var string
     *
     * @ORM\Column(name="txt", type="text")
     */
    private $txt;
...

而这种形式:

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('int')
            ->add('txt')
        ;
    }

我有这样的看法:

{% extends "TotalcanBravofillBundle::index.html.twig" %}

{% block content %}
    {{ form_errors(form) }}
    {{ form_widget(form) }}
{% endblock %}

它不起作用；我收到以下错误:

Could not load type "text"
500 Internal Server Error - InvalidArgumentException

我究竟做错了什么？

在构建表单时，您没有声明实体到字段的任何映射:http://symfony.com/doc/current/book/forms.html#building-the-form

这应该有效:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('int', 'int')
        ->add('txt', 'text')
    ;
}

我强烈建议不要重命名 Symfony2 字段映射 as in the other answer - 每次升级 Symfony 时，您的代码都会中断。
