How can I update Reminder with Reminder.Draft?

[tiendq]

Form (from Reminders example):

struct ReminderFormView: View {
  @State var reminder: Reminder.Draft
}

Then save reminder with Reminder.upsert(). Now I want to do create/update separately:

Reminder.insert { reminder } is ok, but Reminder.update(reminder) causes following error. Why does update not support draft type same as insert and upsert?

Cannot convert value of type 'Reminder.Draft' to expected argument type 'Reminder'

UPDATE statements require a primary key to execute, but Draft types may not have one. The upsert function is what we provide for either creating or updating using a draft type. If you want to separate create/update, your create flow can use Reminder.Draft, and your update flow can use Reminder. If you're writing code that you think should work can you provide more context and suggestions for how our APIs should change?

update could check if id is nil or just letting an error thrown, updating an object without an ID is developer fault :). Using a draft in a create/edit form is more convenient, but if I need to use both Draft for creating and Reminder for updating I'd rather use Reminder only (and handle nil ID manually).

Because update(_:) builds its WHERE from the primary key: it ends in .where { $0.primaryKey.eq(...) }, reading the id off the row. A Draft's primary key is optional — that's the whole point of the type — so there's no id to filter on. insert and upsert don't need one; upsert is documented as "updating an existing row if the draft has an ID or inserting a new row if the ID is nil".

If you want the two paths separate, don't go through the row overload — set columns against the id you already have:

Reminder.update { $0.title = reminder.title }
  .where { $0.id.eq(id) }

Sorry, I am directing that towards @CedricConday :)

I'm also a human. I disclosed my AI usage in my profile. Marking me as spam is just rude. If the answer didn't suffice, you could have said that. No hard feelings. I understand your AI hate, but at least be human and ask or talk to me.

@CedricConday There is no AI disclosure in your profile nor in your comments above.

And even if disclosed, you have never participated in any of our repo discussions before, you seem to have never participated in Swift language discussions on GitHub before, and you gave a very generic, obtuse, non-answer to the question.

There's no need to respond to this and further derail this discussion. You can move on to other repos.

I think it's AI too, we usually put a link to a LOC we mentioned, and not "(TableMacro.swift:608)" :)

[CedricConday]

Would the two of you like an apology? As a human I wasn't capable in my own accord to complete the task without AI assistance. Was the answer right? I will excuse myself for being annoyance while only trying to help.

[CedricConday]

Sorry, but no. You thought vibe coder when I am not. I won’t move on. You write good prose, but you don’t do real research. I’ll keep answering. :)
