Django模板：用HTML翻译文本块的最佳做法 [英] Django templates: Best practice for translating text block with HTML in it

问题描述

在Django模板中，如何翻译包含HTML的块？例如：

In Django templates, how would I translate a block that contains HTML? For example:

{% trans "Please" %}
    <a href="{% url login %}?next={{ currentUrlPath }}">
        {% trans "log in" %}
    </a>
{% trans "in order to use MyApplicationName." %}

拆分翻译的字符串可让我随时更改模板中的HTML，但是假设将它变成一个单一的翻译字符串会更有意义，如下所示：

Splitting up translated strings allows me to change the HTML in the template at any time, but I guess it would make more sense to put it into a single translation string, like so:

{% url login as loginUrl %}
{% blocktrans %}
    Please
    <a href="{{ loginUrl }}?next={{ currentUrlPath }}">
        log in
    </a>
    in order to use MyApplicationName.
{% endblocktrans %}

但是，HTML标记在翻译字符串中，即如果我想要更改HTML（例如，锚的CSS类），我必须重新翻译每个语言的字符串。

But then the HTML markup is in the translation string, i.e. if I wanted to change the HTML (e.g. CSS class for the anchor), I'd have to retranslate the string for each language.

有更好的选择吗？ / p>

Are there any better alternatives?

推荐答案

从文档：

不可能混合模板{％trans％}内的字符串中的变量。如果您的翻译需要使用变量（占位符）的字符串，请使用{％blocktrans％}。

It's not possible to mix a template variable inside a string within {% trans %}. If your translations require strings with variables (placeholders), use {% blocktrans %} instead.

然后在 blocktrans ：

要翻译模板表达式 - 例如访问对象属性或使用模板过滤器 - 需要将表达式绑定到本地变量以在翻译块中使用。示例：

To translate a template expression -- say, accessing object attributes or using template filters -- you need to bind the expression to a local variable for use within the translation block. Examples:

{% blocktrans with article.price as amount %}
That will cost $ {{ amount }}.
{% endblocktrans %}

{% blocktrans with value|filter as myvar %}
This will have {{ myvar }} inside.
{% endblocktrans %}

这样你的翻译字符串有占位符。在你的情况下：

This way your translated strings have the placeholders. In your case:

{% blocktrans with login_object.anchor as anchor %}
    Please {{ anchor|safe }}log in</a> in order to use MyApplicationName.
{% endblocktrans %}

您将需要生成 anchor 在您的视图功能。这样就可以避免您的翻译字符串。

You will need to generate the text that goes in anchor in your view function. This keeps it out of your translated string.
