How do you sort a list in Jinja2?

Question

I am trying to do this:

 {% for movie in movie_list | sort(movie.rating) %}

But that's not right...the documentation is vague...how do you do this in Jinja2?

As of version 2.6, Jinja2's built-in sort filter allows you to specify an attribute to sort by:

{% for movie in movie_list|sort(attribute='rating') %}

Thanks, that's exactly what I wanted. By the way, does it work with both types of attributes...you know __getattr__ and __getitem__ ? (because I can't remember whether "movies" were objects or dictionaries) – Nick Perkins Mar 31 '11 at 23:28
@Nick: I did a quick test, and it seemed to work with both objects and dicts. – Steve S Apr 01 '11 at 15:39

Nice, this also works for a tuple index: `list_of_tuples|sort(attribute='0')` – Navin Jul 11 '18 at 19:11

It could be handy to display values in reverse orders (it could be interesting for ratings for example), in this case just use the option `reverse=True`. – Romain Oct 21 '18 at 19:20

If you want to sort in ascending order

{% for movie in movie_list|sort(attribute='rating') %}

If you want to sort in descending order

{% for movie in movie_list|sort(attribute='rating', reverse = True) %}
