我有两种模式,一种是Bonsai,另一种是任务:

@Model
final class BonsaiModel {
    var uuid: UUID
    var timestamp: Date
    var purchased: Date
    var price: Int
    var name: String
    var isFavorite: Bool
    var age: Int

    @Attribute(.externalStorage)
    var bonsaiImageData: Data?

    @Relationship(deleteRule: .nullify, inverse: CategoryModel.bonsai)
    var category: CategoryModel?
    @Relationship(deleteRule: .nullify, inverse: SpeciesModel.bonsai)
    var species: SpeciesModel?

    @Relationship(deleteRule: .cascade, inverse: TaskModel.bonsai)
    var newTaskModel: [TaskModel] = []

    @Relationship(deleteRule: .cascade, inverse: BonsaiImageModel.bonsai)
    var bonsaiImages: [BonsaiImageModel] = []

    init(name: String = "",
         isFavorite: Bool = false,
         bonsaiImageData: Data? = nil
    ) {
        self.uuid = UUID()
        self.timestamp = Date()
        self.purchased = Date()
        self.price = Int()
        self.name = name
        self.isFavorite = isFavorite
        self.age = 2023
        self.bonsaiImageData = bonsaiImageData

    }

}

@Model
final class TaskModel {
    var uuid: UUID
    var name: String
    var timestamp: Date
    var isComplete: Bool
    @Relationship(deleteRule: .nullify, inverse: CareTypeModel.newTask)
    var careType: CareTypeModel?
    var isDue: Date

    var bonsai: BonsaiModel?

    init(
        name: String = "",
        isComplete: Bool = false
    ){
        self.uuid = UUID()
        self.name = name
        self.timestamp = Date()
        self.isComplete = isComplete
        self.isDue = Date()
    }
}

一个博尼赛人可以承担多重任务。 一切产品都进行罚款。

现在,我要显示几天,直到下一个给某个博尼赛的任务到期。

在我的看法中(令人满意) 我获得这样的数据:

@Environment(.locale) private var locale
    @State var bonsai = BonsaiModel() // To get me one Bonsai.
    @Query private var taskModel: [TaskModel] // To get all Tasks.

My thought was, to get all tasks, then filter tasks to get given Bonsai. Next get the isDue date and in the end, task-date minus actual date equals days left until task.

我曾经有过过滤器,但我没有这样做。 是否有解决办法?
