May I ask how to do list appending on version 1.2.21 about jingoo HOT 3 CLOSED

Hi.

Can you use this?

{% set a = [] %}
{% set a += ["a"] %}
{{ a | length }}

{{ a.append("a") }} is notation for reaching the append attribute of a object and apply the "a" argument to it.

+= only works with 1.3.1+ version, but with 1.3.0 you can use {% set a = a + ["a"] %}

If you want to stick with old version, there is a flatten filter which should achieve the same Oups, flatten was introduced in 1.3.4

from jingoo.

Another option if you really need to stick with older version is to use the filters field of

from jingoo.

Thanks for the quick reply @sagotch !

I think in this case, I would probably try to get a new version which seems easier.

Feel free to consider this issue has been resolved.
