how can apply query in laravel 5? have 3 table, post, profile, comments

i want kind of structure:

comments last_name fist_name

//post model

public function comments(){     return $this->hasmany('app\comments', 'post_id', 'id'); }

//comments model

public function user(){     return $this->belongsto('app\profile', 'user_id'); }

//profile model

public function comments(){     return $this->hasmany('app\comments'); }
