Jinja2 not respecting dict ordering

Question

According to this question, If items(), keys(), values(), iteritems(), iterkeys(), and itervalues() are called with no intervening modifications to the dictionary, the lists will directly correspond.

However in Jinja2 this seems not to be the case, as keys() and values() are giving different orders for me. I'm trying to build a table as follows:

   {% for record in records %}
        {% if loop.first %}
            <tr>
            {% for key in record.keys() %}
                <th>{{ key }}</th>
            {% endfor %}
            </tr>
        {% endif %}
        <tr>
        {% for value in record.values() %}
            <td>{{ value }}</td>
        {% endfor %}
        </tr>
    {% endfor %}

and currently the values don't correspond to the keys. Anyone else come across this?

have not. as workaround: does using `record.items()` and then selecting the key or the value help? or did you consider using an `OrderedDict`? — hiro protagonist, Jul 03 '15 at 17:44

Seems the problem was actually with psycopg.extras.DictCursor2. In the end I used an OrderedDict as suggested by hiro.
