Django 模板 : Best practice for translating text block with HTML in it

Question

在 Django 模板中，我如何翻译包含 HTML 的 block ？例如:

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

拆分翻译后的字符串让我可以随时更改模板中的 HTML，但我想将其放入单个翻译字符串中更有意义，如下所示:

{% 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，也就是说，如果我想更改 HTML(例如 anchor 的 CSS 类)，我必须为每种语言重新翻译字符串。

有没有更好的选择？

来自 the docs :

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下:

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，您翻译的字符串就有了占位符。在你的情况下:

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

您需要在 View 函数中生成进入 anchor 的文本。这会将它排除在翻译后的字符串之外。
