如何在Twig模板中呈现DateTime对象 [英] How to render a DateTime object in a Twig template

问题描述

我的一个实体中的一个字段是一个datetime变量。

如何将该字段转换为一个字符串以在浏览器中呈现？ / p>

这是一个代码片段：

  {％游戏中的游戏％} 
 ... 
< td> {{game.gameTeamIdOne.teamName}}< / td> 
< td> {{game.gameTeamIdTwo.teamName}}< / td> 
< td> {{game.gameDate}}< / td> 
< / tr> 
 {％endfor％} 
  

这是我的实体类中的变量：

  / ** 
 * @var date $ gameDate 
 * 
 * @ ORM\Column name =GAME_DATE，type =datetime，nullable = true）
 * / 
 private $ gameDate; 
  

这里是我收到的错误消息：

渲染模板时抛出异常（Catchable致命错误：DateTime类的对象无法转换为... \app\cache\中的字符串第10行中的BeerBundle：Games：gameTable.html.twig中的dev \twig\9b\ad\58fd3bb1517632badf1fdc7fa4a8.php line 33）

解决方案

虽然可以使用

  {{game .gameDate | date（'Ym-d'）}} 
  

方法，请记住，这个版本不尊重用户区域设置，这不应该是仅一个国籍的用户使用的站点的问题。国际用户应该显示游戏日期完全不一样，例如扩展 \DateTime 类，并添加一个 __ toString（）

修改：

如@Nic在评论中所指出的那样，如果您使用 Twig的Intl扩展版，您将有一个 localizeddate 可用过滤器，显示用户区域设置中的日期。这样你就可以放弃我以前的想法，扩展 \DateTime 。

One of my fields in one of my entities is a "datetime" variable.

How can I convert this field into a string to render in a browser?

Here is a code snippet:

{% for game in games %}
    ...
        <td> {{game.gameTeamIdOne.teamName}} </td>
        <td> {{game.gameTeamIdTwo.teamName}} </td>
        <td> {{game.gameDate}}</td>
    </tr>
{% endfor %}

Here is the variable in my entity class:

/**
 * @var date $gameDate
 *
 * @ORM\Column(name="GAME_DATE", type="datetime", nullable=true)
 */
private $gameDate;

And here is the error message I am getting:

An exception has been thrown during the rendering of a template ("Catchable Fatal Error: Object of class DateTime could not be converted to string in ...\app\cache\dev\twig\9b\ad\58fd3bb1517632badf1fdc7fa4a8.php line 33") in "BeerBundle:Games:gameTable.html.twig" at line 10.

解决方案

Although you can use the

{{ game.gameDate|date('Y-m-d') }}

approach, keep in mind that this version does not honor the user locale, which should not be a problem with a site used by only users of one nationality. International users should display the game date totally different, like extending the \DateTime class, and adding a __toString() method to it that checks the locale and acts accordingly.

Edit:

As pointed out by @Nic in a comment, if you use the Intl extension of Twig, you will have a localizeddate filter available, which shows the date in the user’s locale. This way you can drop my previous idea of extending \DateTime.
