Sorry if this is too basic, but I really can't figure out how to make this work.
I am trying to make a journal app and I want to have a button that creates a new journalentry and then loads it. This code snippet (I removed irrelevant bits) shows how I'm trying to go about it. Basically, the newEntryButtons should launch a JournalPromptRoute for one of the different options: that's the method argument. But putting .createNewEntry() inside the argument means that new entries are being constantly created. I want the system to create a new entry once on the button press and then go to it from the navigationDestination area.
Can anyone please explain to me how this is supposed to work? I believe the code snippet is detailed enough to get the point across but please let me know if you need more info.
case library
case blank(entry: Entry)
case mystery
case summary(entry: Entry)
case entry(entry: Entry)
}
struct JournalHome: View {
@ObservedObject var viewModel: JournalViewModel
var mainContent: some View {
ScrollView {
newEntryButtons
LazyVStack {
ForEach(filteredEntries) { entry in
NavigationLink(
value: JournalPromptRoute.entry(entry: entry)
) {
JournalCard(entry)
}
}
}
}
}
var body: some View {
NavigationStack(path: $path) {
mainContent
.navigationDestination(for: JournalPromptRoute.self) { route in
switch route {
case .blank(let entry):
JournalEntryView(
entry: entry,
index: 0,
viewModel: viewModel
)
}
}
}
}
var newEntryButtons: some View {
ScrollView(.horizontal) {
HStack(spacing: 15) {
EntryButton(
description: "Add blank entry",
method: JournalPromptRoute.blank(entry: viewModel.createNewEntry()),
viewModel: viewModel,
path: $path
)
EntryButton(
description: "Select a Journey",
method: JournalPromptRoute.library,
viewModel: viewModel,
path: $path
)
EntryButton(
description: "Let the Journey find you",
method: JournalPromptRoute.mystery,
viewModel: viewModel,
path: $path
)
}
}
}
}
