I have a laravel app with an Order Model that HasMany OrderLines, and HasMany OrderAddresses.

In order to save an Order I run this function, which works great, but uses 9 queries to run. Can you help me figure out how to run this faster.

  public function save(array $options = array()) {
    $exists = static::where('OrderID', '=', $this->OrderID)->first();

    if( ! $exists) {
      parent::save($options);
      $exists = static::where('OrderID', '=', $this->OrderID)->first();
    }else {
      Log::info("Updating already inserted record with OrderID = $this->OrderID");
      parent::where('OrderID','=',$this->OrderID)->update($this->getAttributes());
    }

    if(isset($this->addresses)) {
      foreach($this->addresses as $a) {
        $a -> order_id = $exists->id;
        if($a -> AddressType == 'ShippingInfo') {
          if($s = $exists->shippingAddress()->first()) {
            $s->update($a->getAttributes());
          }else {
            $a->save();
          }
        }
      }
      foreach($this->addresses as $a) {
        $a -> order_id = $exists->id;
        if($a -> AddressType == 'BillingInfo') {
          if($b = $exists->billingAddress() -> first()) {
            $b->update($a->getAttributes());
          }else {
            $a->save();
          }
        }
      }
    }
    if(isset($this->orderLines) && sizeof($this->orderLines) > 0 ) {
      foreach($this->orderLines as $ord) {
        $ord -> order_id = $exists->id;
        if($ol = OrderLine::where('LineItemID','=', $ord -> LineItemID)->first()) {
          foreach($ord->getAttributes() as $attr => $val) {
            $ol -> $attr = $val;
          }
          $ol -> save();
        }else {
          $ord->save();
        }
      }
    }
  }
