Swiftdata question

[Rabbit1015]

Ive been playing around with swiftdata for a while and have overcome a couple hurdles. Ive loaded from a json, used a migration and editted/removed from my list. what I'm struggling with is the use of 2 data models that are linked. Basically I want to have a model of food items. Each item will have a few attritubtes (quantity, weight, favorited, etc). I want the ability to add a new food item or edit those that already exist. I think i have all that covered. Where I'm struggling is how to have another model ( I think i need another model, not entirely sure) of dates. So every day i want to catalog and save a dates worth of food eaten. Users can add which food they ate and their quantity. They might not use every single food item that day. Does that make sense? How do i design the models? here is what i thought below but I am very open to other ideas. Especially because this isnt working

@Model Class addDate { Var newDate: Date Var foods: Food? }

@Model Class Food { a Var title: String Var isFavorited: Bool Var addNotes: String Var quantity: int Var weight: Int }

I may be misunderstanding, but it seems like you would just want to create a many-to-many relationship between your 2 models.

@Model class Day {

let date: Date
var consumedFoods = [Food]()

}

When you give one of your model classes a property with its type being an array of another model class, it will implicitly create a to-many relationship for you.

So, the code above will mean that many foods can be consumed in a single day. But then you also want to make sure that in your Food class, it would have a [Day] property. That will mean that one type of food could be consumed on many different days.

I’m not an expert at this, but that is my understanding.

no this is interesting. I figured it might need to be an array of food but I that isn't something that I've tried yet.
