Django i18n blocktrans vs trans

Question

在Django模板中，这两者到底有什么区别:

{% blocktrans %}My Text{% endblocktrans %}

{% trans 'My Text' %}

Answer 1

来自 Django Docs

Trans 模板标签

The {% trans %} template tag translates either a constant string (enclosed in single or >double quotes) or variable content:

使用 Trans 标签，您只能使用单个常量字符串或变量。所以你必须使用

{# These Would Work! #}
title>{% trans "This is the title." %}</title>
<title>{% trans myvar %}</title>

但是不能用

{%trans "This is my title {{ myvar }}" %}

Blocktrans 模板标签

Contrarily to the trans tag, the blocktrans tag allows you to mark complex sentences consisting of literals and variable content for translation by making use of placeholders:

使用 Blocktrans，这种代码是可能的:

    {% blocktrans with book_t=book|title author_t=author|title %}
       This is {{ book_t }} by {{ author_t }}
    {% endblocktrans %}

因此，Blocktrans 将允许您在输出中变得更加复杂和完整。

但是从字面上回答你的问题:不多。除了呈现风格，两者都将作为字符串 'My Text' 发送给翻译人员。
