我将日期时间表单字段标记为只读。由于这个接缝没有效果，我否决了默认的树枝模板。这工作正常。

{% block datetime_widget %}
    {% if read_only %}
        {{ value.date.year }}-{{ value.date.month }}-{{ value.date.day }} {{ value.time.hour }}:{{ value.time.minute }}
    {% else %}
        {{ parent() }}
    {% endif %}
{% endblock %}

这是我正在使用的表单类型：

/**
 * @ORM\Entity
 */
abstract class BusinessClass
{

    /**
     * @ORM\Column(type="datetime")
     * @var \DateTime
     */
    private $created;

    /**
     * @return \DateTime
     */
    public function getCreated()
    {
        return $this->created;
    }

}

这就是将日期时间字段添加到表单构建器的方式：

$formBuilder->add('created', 'datetime', array('read_only' => true));

但是，symfony 仍然尝试将未更改的值设置回我的表单类型。由于它是只读的，我只实现了一个 get 方法，但没有实现 set 方法。这就是我收到此错误消息的原因：

InvalidPropertyException: Neither element "created" nor method "setCreated()" exists in class "Cinergy\ShopBundle\Tests\Functional\TestBundle\Entity\RecurringProduct"

由于这是我的业务逻辑的一部分，我不想实现 setCreate 方法。还值得一提的是，同样的事情也适用于文本字段。

如果设置了选项，关于如何阻止 symfony 设置值的任何想法read_only？

简短的回答是：使用disabled而不是read_only.

在文档中找到相关部分后，我认为日期时间的呈现read_only不正确。只有设置read_only没有改变。根据文档，它应该被重新定义为只读 HTML。

不幸的是，如果将映射字段设置为禁用，则不会保留它。它的值变为空，这可能不是 OP 正在寻找的。另一种解决方案是在您的模板中执行以下操作：

{% if household.dateAdded is not null %}{{ household.dateAdded|date('m/d/Y') }}
<input type="hidden" name="household[dateAdded]" value="{{ household.dateAdded|date('m/d/Y') }}">
{% endif %}

其中family 是表单名称，dateAdded 是映射的字段名称。
