use Illuminate\Database\Eloquent\Model as Eloquent;

class User extends Eloquent {

// Note: Adding relationships to a pivot model means
// you'll probably want a primary key on the pivot table.
public function posts($value) {
return $this->hasMany('Post'); // example relationship on a pivot model
}
