Symfony:将日期时间表单字段设置为只读 [英] Symfony: Make a datetime form field really read-only

问题描述

我将日期时间表单字段标记为read_only.由于此接缝无效，因此我否决了默认的树枝模板.效果很好.

I marked a datetime form field as read_only. Since this seams to have no effect I overruled the default twig template. This works fine.

{% 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:

This is the form type I'm using:

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

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

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

}

这是将datetime字段添加到表单构建器的方式:

And this is how the datetime field is added to the form builder:

$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，因此我仅实现了get方法，而没有实现set方法.这就是为什么我收到此错误消息的原因:

However, symfony still tries to set the unchanged value back to my form type. Since it's read-only I only implemented a get method but not set method. That's why I get this error message:

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

因为这是我的业务逻辑的一部分，所以我不想实现setCreate方法.还值得一提的是，对于文本字段，同样的事情也可以正常工作.

Since this is part of my business logic I don't want to implement a setCreate method. It's also woth mentioning, that the very same thing works fine for text fields.

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

Any ideas about how I can stop symfony from setting the value if the read_only option is set?

推荐答案

简短的答案是:使用disabled而不是read_only.

The short answer is: Use disabled instead of read_only.

在文档中找到相关部分我认为read_only的datetime呈现不正确.仅设置read_only不变.根据文档，应将其改写为只读HTML.

After finding the relevant part in the docs I think that the rendering of datetime for read_only is not correct. Only setting read_only is changing nothing. According to the docs it should be rednered as read only HTML.
