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

我的实体之一中的一个字段是日期时间"变量.

如何将此字段转换为字符串以在浏览器中呈现?

这是一个代码片段:

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

这是我的实体类中的变量:

/*** @var 日期 $gameDate** @ORMColumn(name="GAME_DATE", type="datetime", nullable=true)*/私人 $gameDate;

这是我收到的错误消息:

<块引用>

模板渲染过程中抛出异常(Catchable Fatal Error: Object of class DateTime could not be convert to string in ...appcachedev wig9bad58fd3bb1517632badf1fdc7fa4a8.php第 33 行")在第 10 行的BeerBundle:Games:gameTable.html.twig"中.

解决方案

虽然你可以使用

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

方法，请记住，此版本不尊重用户区域设置，这对于仅由一个国籍的用户使用的站点应该不是问题.国际用户应该显示完全不同的游戏日期，比如扩展 DateTime 类，并添加一个 __toString() 方法来检查区域设置并采取相应的行动.>

编辑:

正如@Nic 在评论中指出的那样，如果您使用 国际扩展的 Twig，您将有一个 localizeddate 过滤器可用，它显示用户的语言环境中的日期.这样你就可以放弃我之前扩展 DateTime 的想法.

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
 *
 * @ORMColumn(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 ...appcachedev wig9bad58fd3bb1517632badf1fdc7fa4a8.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.
