How to render author custom fields info on comment and node twig template?

Question

I am trying to render the author Full Name and other authors customs fields information in comment.html.twig and node.html.twig. But not any of the fields that I made for users such as "First Name", "Last Name", and Auther UID etc. render in comments.

I tried with the following code for comment author

{{ comments.author.field-first_name.entity.value }}
{{ comment.author.user_picture.0.entity.uri.value }}
{{ comments.author.uid.entity.value }}

And, I tryed following code for node author:

{{ node.author.field-first_name.entity.value }} {{ node.author.user_picture.0.entity.uri.value }} {{ node.author.uid.entity.value }}

Any ideas, how do I render this info in comment template?

Answer 1

For Node:

{{ node.getOwner.field_first_name.value }}
{{ file_url(node.getOwner.user_picture.entity.fileuri) }}
{{ node.getOwner.uid.value }}

For Comment:

{{ comment.getOwner.field_first_name.value }}
{{ file_url(comment.getOwner.user_picture.entity.fileuri) }}
{{ comment.getOwner.uid.value }}

To find a solution I would first check, if the information I want to display is in the actual render array. You can do this by using a variable dump.

{{ dump(comments|keys }}

or

{{ dump(comments.author|keys }}

(If you have devel with kint installed, you can use this vor variable dump.)

Now you can look: If your first-name field is not in the render array, then no template will be possible to show it.
