php - separating relationships and model functions in Laravel -

everytime i'm writing laravel model gives me feeling of messy code. have relationships , other model functions specially when using domain driven design. though separating relationships , functions.

example have user class extends eloqeunt:

class user extends eloquent{} 

and inside class have register functions , password hashing functions etc. also, can declare relationships so:

class user extends eloquent{     function post(){         return $this->hasmany('post');     } } 

for reason smells funky me. solution create entities folder , inside create user folder hold 2 files 1 userrelationship hold of the relationships class:

   class userrelationship extends eloquent{         function post(){             return $this->hasmany('post');         }     } 

and second actual user class write of functions , class extend userrelationship class instead of eloquent:

class user extends userrelationship{      public static function register($email, $password, $activate_token)     {         $user = new static(compact('email', 'password', 'activate_token'));          $user->raise(new userwasregistered($user));          return $user;     } } 

what guys think of approach relatively new don't know if bad practice or work little reward. guys recommend?

for user model, work. easiest way , still better approach define relationship in user model. if example post model have relationships post "user, comment, reply etc" can attempt splitting relationships
