I have two tables

• products (model: Products)

• product_common_auction (model: ProductCommonAuction)

Each Product can have one record on ProductCommonAuction (hasone() in Product models)

Each ProductCommonAuction belongs to one row in Porduct

When I want to save a model I use the following code to save a product with it's relation:

		$Product = new Products();

		$Product->title = $toSave['auction_title'];

		$Product->body = $toSave['auction_description'];

		$Product->price = 50000;

		$Product->product_type_id = 1;

		$Product->sku = time();

		$Product->enabled = ((!empty($toSave['enabled']))?1:0);

		$Product->approved = 1;

		$Product->save();

		$Common = new ProductCommonAuction();

		$Common->product_id = $Product->id;

		$Common->save();

I also can get results with this:

		$Product = new Products();

		$Product->title = $toSave['auction_title'];

		$Product->body = $toSave['auction_description'];

		$Product->price = 50000;

		$Product->product_type_id = 1;

		$Product->sku = time();#to do

		$Product->enabled = ((!empty($toSave['enabled']))?1:0);

		$Product->approved = 1;

		$Product->save();

		$Product->common_auction()->save(new ProductCommonAuction);

Which one is better ?
