python 3.x - In a nested for-loop, how can I access the outer loop index in a jinja template? -

{{loop.index}} correctly dereferences innermost loop. i'm not seeing way identify loop index i'd like, however, if have more 1 loop nested.

yes. part of documentation answers question!

the special loop variable points innermost loop. if it’s desired have access outer loop it’s possible alias it:

<table> {% row in table %}   <tr>   {% set rowloop = loop %}   {% cell in row %}     <td id="cell-{{ rowloop.index }}-{{ loop.index }}">{{ cell }}</td>   {% endfor %}   </tr> {% endfor %} </table>
