How to get username by id in Laravel?

Question

Laravel

Please advise in this situation.
When creating a post, the id of the user who created this post is also recorded in the database.
How can I specify the author not his id but his name when displaying a list of articles?
Thank you.

Answer 1

Post::find($postId)->author->name;
Post::with('author')->find($postId)->author->name;
