reverse
The reverse
filter reverses a sequence, a mapping, or a string:
{% for user in users|reverse %} ... {% endfor %} {{ '1234'|reverse }} {# outputs 4321 #}
Tip
For sequences and mappings, numeric keys are not preserved. To reverse them as well, pass true
as an argument to the reverse
filter:
{% for key, value in {1: "a", 2: "b", 3: "c"}|reverse %} {{ key }}: {{ value }} {%- endfor %} {# output: 0: c 1: b 2: a #} {% for key, value in {1: "a", 2: "b", 3: "c"}|reverse(true) %} {{ key }}: {{ value }} {%- endfor %} {# output: 3: c 2: b 1: a #}
