php - Laravel Eloquent - equivalent to first() for last? -

i have few models such user, post, comment, etc.

in user, have:

public function posts()  {    return $this->hasmany('post');  }

i can first post via $customer->posts()->first(), if want latest post? there no last() can see.

this further compounded hasmanythrough relationship (unfortunately inherited wacky schema):

public function comments()  {      return $this->hasmanythrough('comment', 'post'); }

if try $this->comments()->orderby('comments.id', 'desc')->first(); returns user object??

no, this

// user model $this->comments()->orderby('comments.id', 'desc')->first();

won't return user model.

and asked for, this:

$customer->posts()->latest()->first();
