How to pass selected, named arguments to Jinja2's include context?

Question

Using Django templating engine I can include another partial template while setting a custom context using named arguments, like this:

{% include "list.html" with articles=articles_list1 only %}
{% include "list.html" with articles=articles_list2 only %}

As you may be supposing, articles_list1 and articles_list2 are two different lists, but I can reuse the very same list.html template which will be using the articles variable.

I'm trying to achieve the same thing using Jinja2, but I can't see what's the recommended way, as the with keyword is not supported.

Answer 1

Jinja2 has an extension that enables the with keyword - it won't give you the same syntax as Django, and it may not work the way you anticipate but you could do this:

{% with articles=articles_list1 %}
    {% include "list.html" %}
{% endwith %}
{% with articles=articles_list2 %}
    {% include "list.html" %}
{% endwith %}

However, if list.html is basically just functioning as a way to create a list then you might want to change it to a macro instead - this will give you much more flexibility.

{% macro build_list(articles) %}
    <ul>
        {% for art in articles %}
            <li>{{art}}</li>
        {% endfor %}
    </ul>
{% endmacro %}

{# And you call it thusly #}
{{ build_list(articles_list1) }}
{{ build_list(articles_list2) }}
