如何使用“include"在 Django 中动态包含模板标签 [英] How to include templates dynamically in Django using "include" tag

问题描述

我有 10 个 html 文件，名称分别为 1.html、2.html ..etc我要的是根据一个变量，模板中应该包含某个文件.

I have 10 html files with the names 1.html, 2.html ..etc What I want is according to a variable, a certain file should be included in the template.

例如

{% if foo.paid %}
    {% include "foo/customization/{{ foo.id }}.html" %}
{% endif %}

这可能吗?因为 foo.id 在 includes 标签起作用之前没有被翻译.结果它给出了一个错误.如何以不同的方式处理这个问题?我应该为此创建一个自定义模板标签吗?

Is this possible ? Cause the foo.id is not being translated before the includes tag works. As a result its giving a error. How can this issue be handled in a different way ? Should I create a custom template tag for this ?

推荐答案

您可以使用 添加过滤器 和带声明 .

{% if foo.paid %}
    {% with template_name=foo.id|stringformat:"s"|add:".html" %}
        {% include "foo/customization/"|add:template_name %}
    {% endwith %}
{% endif %}

首先构建一个 template_name，它由字符串格式的 foo.id 和 .html 组成.然后将其传递给 include 标记，并与模板目录的路径连接.

First you build a template_name, which consist of foo.id in string format concatenated with .html. Then you pass it to include tag, concatenated with path to template directory.
