Laravel merge relationships

Is there a way to merge 2 relationships in laravel?

this is the way it’s setup now, but Is there a way I could return both merged?

  public function CompetitionsHome() {
    return $this->HasMany( 'Competition', 'home_team_id' );
  }
  public function CompetitionsGuest() {
    return $this->HasMany( 'Competition', 'guest_team_id' );
  }
  public function Competitions() {
    // return both CompetitionsHome & CompetitionsGuest
  }

Answer

Try out getter method for property which returns merged collections returned from relations.

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);
}

Or you can call additional methods before collection is returned to get different result sets.

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);
}
