Laravel, “withTrashed()” linking a deleted relationship

We have DB table posts, which is linked to table users with a field posts.user_id = users.id.

class User extends Model {
 
    use SoftDeletes;
    ......
}

With Eloquent we can define the relation easily.

class Post extends Model {
    public function user() {
        return $this->belongsTo('App\User');
    }
}

If the user gets deleted, and on the User model we use the SoftDeletes trait, you can use withTrashed() method here.

class Post extends Model {
    public function user() {
        return $this->belongsTo('App\User')->withTrashed();
    }
}

then just $post->user

or just simple use the relationship method to return the user

$post->user()->withTrashed()->get()
$post->user()->withTrashed()->first()
