Highly struggling with understanding basic associations

[freak4pc]

Hey there :)
I'm trying to set up associations for the first time and having a really hard time.

The set-up is really not obvious and there's no diagnostic to tell you if anything was wrong (no actual failure or fatalError in DEBUG, etc.). A lot of "f***ing around, finding out", but I'm stuck, so here we are :)

Here's the setup I have, give or take:

struct Message: ... conformances {
    static let databaseTableName = "messages"
    static let reactions = hasMany(Message.Reaction.self)

    let id: ...
}

extension Message {
    struct Reaction: ... conformances {
        static let databaseTableName = "reactions"
        static let message = belongsTo(Message.self)
        
        let messageId: ...
    }
}

Whatever I try to do, for example this:

try Message
    .including(all: Message.reactions)
    .fetchAll(db)

doesn't seem to work.

Inside my init(row:) (of message), I tried printing row.columnNames and reactions isn't there. Also trying reading row["reactions"] but it turns up empty.

Would appreciate any help with this, and hopefully it'll help me understand how it all works :)

Tried a lot of messing around specifying key, foreignKey, etc, but nothing helps.

Ok, so it's working now.
The issue is I was checking if row.hasColumn("reactions") which doesn't work. I just removed it and everything is working now.
I am confused thought with why it's not working, I have a different association where it worked 🤷

Thanks anyways!
