So we didnt need to do repeat things like this

public function editAmountMediaPart($media_type, $media_id, $amount) {
    if($media_type == "braille") {
      $media = Braille::find($media_id);
      $lastItem = Brailledetail::where('braille_id', '=', $media_id)->get();
      $currentAmount = $lastItem->last()->part;
      if($amount - $currentAmount > 0) {
        for($i=$currentAmount + 1; $i<=$amount; $i++){
          $brailledetail = new Brailledetail();
          $brailledetail->part = $i;
          $brailledetail->status = 0;
          $brailledetail->date = (date("Y") + 543).date("-m-d H:i:s");
          $brailledetail->braille()->associate($media);
          $brailledetail->save();
        }
      }
      else {
        for($i=$currentAmount; $i>$amount; $i--){
          $brailledetail = Brailledetail::where('part', '=', $i);
          $brailledetail->delete();
        }
      }
    }
    else if($media_type == "cassette") {
      $media = Cassette::find($media_id);
      $lastItem = Cassettedetail::where('cassette_id', '=', $media_id)->get();
      $currentAmount = $lastItem->last()->part;
      if($amount - $currentAmount > 0) {
        for($i=$currentAmount + 1; $i<=$amount; $i++){
