Action > Template parameters (internal)

This internal specification now delegates most user-facing documentation to the public page
/guides/users/rules-engine/templates/index.md, which describes:

• Template syntax and Twig delimiters.
• Available Twig filters and basic examples.
• Product‑Live specific functions: source, target, loadChildren, base64_encode, base64_decode.
• Template engines (twig.1, twig.2) and their behavior.
• Error handling rules, playground usage, and XML examples.

The sections below keep only additional internal examples and known limitations that are not required in the public documentation.

Macros

Macros are reusable pieces of code that can be used to simplify your Twig code.

Get the ident

{% macro getIdent(data) %}
    {% for field in data.fields %}
        {% if field.key == 'ident' %}
            {{ field.value.data }}
        {% endif %}
    {% endfor %}
{% endmacro %}

{% set v = _self.getIdent(sourceItem) %}
{{ v }}

WARNING

The returned value is a string.

Known issues

• We use Twing.js and it has some shortcomings on the Twig syntax.
  In particular, it does not support the sort filter or accessing an array element by numeric index.
