I have taken a look at Polymorphic associations and STI but I don't really know if they apply to my specific use case. In my app I have the following relevant classes:
class Restaurant < ApplicationRecord belongs_to :owner, class_name: "User" has_many :menus has_many :dishes has_many :categories has_many :bookings has_many :simple_bookings mount_uploader :photo, PhotoUploader end class Dish < ApplicationRecord has_many :menu_dishes has_many :menus, through: :menu_dishes belongs_to :category belongs_to :restaurant mount_uploader :photo, PhotoUploader end class Menu < ApplicationRecord belongs_to :restaurant has_many :bookings has_many :categories has_many :menu_dishes has_many :dishes, through: :menu_disheshas_many :menu_dishes end class MenuDish < ApplicationRecord belongs_to :dish belongs_to :menu end
So far the user flow is the following: A restaurant owner signs up and creates restaurant dishes. Then this owner creates a menu containing different MenuDishes. Afterwards, users can search for different menus and book them.
My problem is the following: I want to implement a feature where owners can add up to 3 MenuDishOptions (that belong to MenuDishes) so that a user can change each MenuDish with the available MenuDishOption for that MenuDish.
In other words, I want each MenuDish to contain many MenuDishOptions. Once a MenuDishOption is selected, the MenuDish passes to be a MenuDishOption and the selected MenuDishOption to a MenuDish.
Therefore the MenuDishOption class would look something like this:
class MenuDishOption < ApplicationRecord belongs_to :menu_dish has_one :dish belongs_to :menu, through: menu_dishes end
The MenuDish class would be updated to:
class MenuDish < ApplicationRecord has_many :menu_dish_options belongs_to :menu belongs_to :dish end
Please let me know if I need to share more info and thanks a million to anyone that takes the time to help this newbie.
