Hi guys,

I'm wondering how to deal with this situation:

I have this structure:

Ingredients (basic list of ingredients)

• id
• name

Groceries (basic list of groceries)

• id
• name

Recipe (recipe which is made from ingredients and/or groceries)

• id
• name

Recipeables (pivot table)

• id
• recipe_id
• recipeable_id
• recipeable_type
• order
• value

recipeable is FQN to an ingredient or grocery

I have this panel:

• and after button click I want to attach the ingredient or the grocery to the recipe
• at the end I have these table of attached ingredients or groceries, sorted by an order, all in one table:

I'm trying to figure out best code solution, here is what I have so far, but I still have little feeling, that there is a better solution.

// Service
class AddRecipeableToRecipeService
{

	/**
	 * @param Recipe $recipe
	 * @param RecipeableRequest $request
	 */
	public function add(Recipe $recipe, RecipeableRequest $request)
	{
		$recipeable = Helper::getRecipeableModel(
			$request->input('recipeable'),
			$request->input('type')
		);

		$value = (int) $request->input('value');
		$order = (int) $request->input('order');

		$attributes = compact('value', 'order');

		if ($recipeable->hasMacronutrients() === TRUE) {
			$attributes += $recipeable->ratio($value);
		}
 
		// type is "recipe" or "grocery"
		$recipe->{str_plural($request->input('type'))}()->attach($recipeable, $attributes);
	}
}


// Helper
class Helper
{

	/**
	 * @var string[]
	 */
	private static $model = [
		'ingredient' => Ingredient::class,
		'grocery'    => Grocery::class,
	];



	/**
	 * @param int $ID
	 * @param string $type
	 * @return Ingredient|Grocery
	 */
	public static function getRecipeableModel($ID, $type)
	{
		return app(self::$model[$type])->findOrFail($ID);
	}
}

// Remove example
DB::table('recipeables')->delete($id);

What do you think? I don't know, how to work with editing, I need pivot values and model too.

Thanks a lot
