I want to sort a list by length, but I'm not sure if it is possible with Jinja2:

{% for item in item_list | sort(length) %}

@juliansalas it is by attribute, I would like by length of items — Jose Angel, May 05 '17 at 14:44

If item is your custom class, you can override __lt__ and you'll be able to sort directly with the sort filter. Since Jinja 2.6, you have a length attribute on your item, you can do so with sort(attribute='length'). Taken from the Jinja2 sort filter documentation
