@DTS Engineer I think the code below works, ill keep testing and update you,
import SwiftUI
import SwiftData
struct SwiftUIView<T: PersistentModel>: View {
@Bindable var dataModule: T
var keyPath: KeyPath<T, String>
var body: some View {
HStack(alignment: .top) {
Text(dataModule[keyPath: keyPath])
}
}
}
#Preview {
do {
let configuration = ModelConfiguration(isStoredInMemoryOnly: true)
let container = try ModelContainer(for: Patient.self, configurations: configuration)
let example = Patient(firstName: "First Name", mobileNumber: "+974 1234 5678", homePhone: "+974 1234 5678", email: "firstname.lastname@gmail.com")
return SwiftUIView(dataModule: example, keyPath: \.firstName)
.modelContainer(container)
} catch {
fatalError("Fatal Error")
}
}
Ok now the solution you suggested raised few more questions and errors as below ..
Now to use the T with text such as Text(T.age) it will complain that T doesn't have no age property ?
Now suppose I want even the property of the T to be also generic and passed to the view as argument how we do it like T.T ? can I see an example ? Im trying to make a generic view that shows any property of any SwiftData module.
Also #Preview is compiling that the generic variable isn't initialized and I wonder how can we initialize a generic variable ?
I get the error .. Missing argument for parameter 'dataModule' in call
import SwiftUI
import SwiftData
struct GenderList2<T: PersistentModel>: View {
@Bindable var dataModule: T
var body: some View {
HStack(alignment: .top) {
Text(T.age)
}
}
}
#Preview {
GenderList2()
}
Hello @Claude31 , thanks for the replay, below is the full code ..
import SwiftUI
import SwiftData
struct PatientsList: View {
@Environment(\.modelContext) var modelContext
@Query(sort: [SortDescriptor(\Patient.firstName), SortDescriptor(\Patient.birthday)]) var patients: [Patient]
var body: some View {
List {
ForEach(patients) { patient in
HStack {
NavigationLink (value: patient) {
PatientRow(patient: patient)
}
}
.alignmentGuide(.listRowSeparatorLeading) { _ in -50 }
.listRowSeparatorTint(sysSecondary02)
.swipeActions(edge: .trailing) {
Button(role: .destructive) {
deletePatient(patient: patient)
} label: {
VStack {
Label("Delete", systemImage: "trash")
Image(systemName: "Trash")
}
}
}
}
}
.scrollIndicators(.hidden)
.foregroundStyle(sysSecondary08)
.listStyle(.plain)
}
func deletePatient(patient: Patient) {
modelContext.delete(patient)
}
init(sort: SortDescriptor<Patient>, searchString: String) {
_patients = Query(filter: #Predicate {
if searchString.isEmpty {
return true
} else {
return $0.firstName.localizedStandardContains(searchString)
}
}, sort: [sort])
}
}
#Preview {
PatientsList(sort: SortDescriptor(\Patient.firstName), searchString: "")
}
@joadan Aha you mean we should explicitly add Destination to Sight in above code ? it won't be implicitly implemented ? that way yes it worked.
I tried the code below, with SiftData models also below, but I got the error .. Value of type Sight has no member destination !
ForEach (destination.sights) { sight in
VStack {
Text(sight.name)
Text(sight.destination.name)
}
}
@Model
class Destination {
var name: String
var details: String
var date: Date
var priority: Int
@Relationship(deleteRule: .cascade) var sights = [Sight]()
init(name: String = "", details: String = "", date: Date = .now, priority: Int = 2) {
self.name = name
self.details = details
self.date = date
self.priority = priority
}
}
@Model
class Sight {
var name: String
init(name: String) {
self.name = name
}
}
Thanks allot, so is there any API or observation method to get notified when some record is changed or that should be done manually as well ?
Kind Regards
Thanks, it's working now, one last question is it possible to use views such as in code below ? maybe for example I want to show to circle buttons ? I remember Apple Mail used this design before ?
Kind Regards
Button(role: .destructive) {
withAnimation {
deletePatient2()
}
} label: {
View1()
}
Button {
deletePatient2()
} label: {
View2()
}
.tint(.orange)
}
Above the foreach there's a line of code "List {" don't know why Apple editor cut it, the code formatting is very bad by the way.
ForEach (patients) { patient in
NavigationLink (value: patient) {
PatientRow(patient: patient)
}
}
.onDelete(perform: deletePatient)
.listRowSeparator(.hidden)
}
.listStyle(.plain)
.buttonStyle(PlainButtonStyle())
.scrollIndicators(.hidden)
.navigationDestination(for: Patient.self) { patient in
PatientDetails(patient: patient)
}
Thanks allot, that doesn't work even when choosing white color the default gray background stays
Thanks allot
