If you notice that you use same relationship often with additional "where" or "orderBy" condition, you can create a separate relationship method.
Model:
// Model:public function comments(){    return $this->hasMany(Comment::class);} public function approvedComments(){    return $this->comments()        ->where('approved', 1);} public function latestApprovedComments(){    return $this->comments()        ->where('approved', 1)        ->orderBy('created_at', 'desc');}
