Get the fields from a reference entity (content type) in a Paragraph field

Question

I have a paragraph field that is a reference entity to the Customer Testimonial content type. A content editor can add the customer-testimonial paragraph and type the name of the testimonial. This will then display the text on the website.

I have made a paragraph--c15a-customer-testimonial.html.twig template file with the following code.

{%
  set c15a = {

    title: content.field_testimonial.entity.field_testimonial_titel,

  }
%}

<div class="component c15a">
    <div>

        <div>Testimonial title</div>

        <h2>{{ c15a.title }}</h2>

    </div>
</div>

Of course, this prints nothing. How can I get the fields from the content type I'm referencing in my paragraph?

Answer 1

The referenced entity is not built yet, so you can't access the formatted field content.

You can get the field value from the database by using the paragraph object:

{{ paragraph.field_testimonial.entity.field_testimonial_titel.value }}

This is unformatted, which might work for a title field.

If you want a formatted output better use a custom view mode for the referenced entity to configure the fields, or in this case one field, if this is all you want to display.
