Symfony的：让真正只读日期时间表单字段(Symfony: Make a datetime fo

我为READ_ONLY打上日期时间表单字段。由于该接缝有没有效果我否决默认树枝模板。这工作得很好。

{% 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;
    }

}

这就是时间字段是如何加入到表单生成器：

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

然而，symfony的仍然试图设置不变值回我的表单类型。因为它是只读的，我只实现了一个GET方法，但不能设置方法。这就是为什么我收到此错误信息：

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，我不希望实现setCreate方法。这也是woth提的是，同样的事情工作正常的文本字段。

我如何能够从如果设定值停止symfony的任何想法read_only选项设置？

Answer 1:

简短的回答是：使用disabled的，而不是read_only 。

找到后，在文档中相关部分我认为日期时间为呈现read_only是不正确的。只有设置read_only是变着法子。根据该文档应该rednered为只读HTML。

Answer 2:

不幸的是，如果一个映射的字段设置为禁用它，然后不持久。它的值变为零，这可能不是什么OP是寻找。另一种解决方案是做这样的事情在你的模板如下：

{% 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，家庭是窗体名称，dateAdded是映射的字段名。
