Setting variable in Jinja for loop doesn't persist between iterations

Question

I want to loop over a list of objects and count how many objects meet a requirement. I based my code off other examples I\'d found, but it doesn\'t work, the count is always

Answer 1

For Jinja <= 2.8, the code you've shown does work. However, this was due to incorrect behavior in Jinja's scope rules, which was fixed in 2.9.

{% for house in city %}
    {% set count = 0 %}
    {% for room in house %}
        {% if room.has_bed %}
            {% set count = count + 1 %}
        {% endif %}
    {% endfor %}
    
{{ house.address }} has {{ count }} beds.
{% endfor %}
