    There are some issues with your template, but I think those are typos. You’re not showing how you’re actually loading the rooms, and I think the issue is in that part.

    The code below works for me. Note that I load the rooms from a string, as you’re not showing how you load it.

    from jinja2 import Template
import json


json_string = """[
    {
        "_id": {
            "$oid": "623492fea76c5404b9f57476"
        },
        "name": "pour ou contre ",
        "created_by": "admin",
        "created_at": {
            "$date": {
                "$numberLong": "1647612670472"
            }
        },
        "subject": "politique"
    },
    {
        "_id": {
            "$oid": "623492fea76c5404b9f57476"
        },
        "name": "no pour ou contre ",
        "created_by": "admin",
        "created_at": {
            "$date": {
                "$numberLong": "1647612670472"
            }
        },
        "subject": "not_politique"
    }
]"""


rooms = json.loads(json_string)
tm = Template("""{% for room in rooms %}
    {% if room.subject == 'politique' %}
       {{ room.name }}
    {% endif %}
{% endfor %}""")

output = tm.render(rooms=rooms)
print(output)

    output
