Principles of templating

This is the Directual syntax for dealing with object fields 📜
For dealing with data in scenarios and filters you can use Templating. Directual Templating system is based on {{ mustache }} library. But there are some useful add-ons to the basic technology.

Basic templating principle

For using the value of the field we are typing its system name in double curly braces: {{field_system_name}}. If we want to fetch the property value of the linked object, we type the field-link, then dot, then the system name of the linked object: {{field_type_of_link.linked_object_field}}.

Inputs for templating

There are two types of input fields for templating. The first is a smart select:
Note, that you can nest the fields of linked objects like {{}}, where book_author is a field type of link. This doesn't work for arrayLinks! To deal with arrayLink fields you may apply Link scenario step.
The second is a text area field. This field has an option to evaluate value as a JavaScript expression (coding mode).
This field also has a smart field inputs option. If it is ON, you'll be able to choose the fields right in text, plus typing "{{" will lead to appearing of that smart inline select. Turn it OFF in case of a need.

Text area input field without smart fields
