如何在{% include } tag django中包含我的参数？

Question

    {% if type == "Cryptography" %}
        {% include 'Cryptography/_____.html' %}
    {% elif type == "Password Cracking" %}
        {% include 'PasswordCracking/_____.html' %}
    {% endif %}

在模板中，我希望包含一些包含1.html 2.html 3.html的HTML页面，这些页面位于C和PC目录中。我尝试过这样做，其中页面是我的参数变量。

    {% if type == "Cryptography" %}
        {% include 'cryptography/'{{page}}'html' %}
    {% elif type == "Password Cracking" %}
        {% include 'PasswordCracking/'{{page}}'.html' %}
    {% endif %}

视图中的

def lessons(request, foo, page):
    return render(request, 'lessons.html', {'type': foo, 'page': page})

注释:类型和页面是我的参数

可以使用add筛选器连接字符串。

{% if type == "Cryptography" %}
    {% include "cryptography/"|add:page|add:".html" %}
{% elif type == "Password Cracking" %}
    {% include "PasswordCracking/"|add:page|add:".html" %}
{% endif %}
