Getting the value of a taxonomy term reference field

Question

I have a content type (Movie) with a taxonomy reference (Movie rating) for which can get multiple values. I would like to use the template node--movie.html.twig and get the first value inserted in the taxonomy term.

I tried using the following code, but it doesn't give any value.

{{ content.field_rating['#items'].getValue()|first.value }}

What am I doing wrong? In which way do I reference the taxonomy term value?

Answer 1

You get the first item out of ['#items] with a "0":

{{ content.field_rating['#items'].0 }}

To get a field from the taxonomy term, I would use the node object, because you don't know how the render array in content will change if you configure the view mode differently:

{{ node.field_rating.0.entity.term_field.value }}

Answer 2

I got the answer of my problem.

Actually first i wanted to show only label or title of term just in my node template. To get the title of first term is like below -

{{ content.field_rating[0]['#title'] }}

OR

{{ node.field_rating.0.entity.label }}

But I got to know that I have to show entire term (comma separated ) with link of term as well. The code below works -

{{ content.field_rating[0] }}
{% for key, value in content.field_rating %}
       {% if key > 0 %}
           {{ ' , ' }}
           {{ content.field_rating[key] }}
        {% endif %}
{% endfor %}
