试用属性的getter方法，该方法返回从关系返回的合并集合。
public function getCompetitionsAttribute($value){ // There two calls return collections // as defined in relations. $competitionsHome = $this->competitionsHome; $competitionsGuest = $this->competitionsGuest; // Merge collections and return single collection. return $competitionsHome->merge($competitionsGuest);}或者，您可以在返回集合之前调用其他方法以获取不同的结果集。
public function getCompetitionsAttribute($value){ // There two calls return collections // as defined in relations. // `latest()` method is shorthand for `orderBy('created_at', 'desc')` // method call. $competitionsHome = $this->competitionsHome()->latest()->get(); $competitionsGuest = $this->competitionsGuest()->latest()->get(); // Merge collections and return single collection. return $competitionsHome->merge($competitionsGuest);}
