How to get the specified value in the array about askama HOT 4 CLOSED

Just use {{ image }} (if you're in a loop). You might also be able to use something like {{ post.images[1] }}.

from askama.

Something like that should work:

{% for image in post.images %}
    {% if loop.index > 6 %}
        {% break %} {# break out of the loop #}
    {% endfor %}
    <img src="{{image_1}}" class="{{loop.index }}" />
{% else %}
    No img {# if the for-loop was never entered #}
{% endfor %}

{% else %}
    No img {# if the for-loop was never entered #}
{% endfor %}

It doesn't work, my images is an images: Vec<String> and when I run it with {% if loop.index %} and{{image_1}}it prompts an error

Just use {{ image }} (if you're in a loop). You might also be able to use something like {{ post.images[1] }}.

            {% let image = post.images.len() %}
            {% if image >=6 %}
                {{post.images[1]}}
                No.2
                {{post.images[5]}}
                {% else %}
                No img
                {% endif %}

Thanks for your tip, I solved this problem by taking the length.
