the params.id will be highlighed red. it should acceppt a v.id('document')

Jamal•2y ago

oh okay where are you getting params.id from? url

DerPenzOP•2y ago

yeah url

DerPenzOP•2y ago

it does not accept the id as string but a v.id() which is idk something else apparently

Jamal•2y ago

v.id is just a typeSafe way for the id to be called. You could convert the url parem.id from a string to _id have you tired to do it even with the error? because i think the ids are just strings under the hood

if I do params.id as Id<'document'> I will get an validator error thats my vscode error: Type 'string' is not assignable to type 'Id<"document">'. Type 'string' is not assignable to type '{ __tableName: "document"; }'.ts(2322)

Jamal•2y ago

but wait there must be a convert method for this lemme check the docs

DerPenzOP•2y ago

Sure but I found nothing

Jamal•2y ago

maybe just cast it? as Id<document> ?

The thread here https://discord.com/channels/1019350475847499849/1141866166126649354 asks a similar question. There's not a way to tell if a string is an ID from the client, so you can either assume the string is an ID (and use v.id("myTable") which will throw when it's not, and myId as Id<"myTable"> to make TypeScript happy), or you can check if the string is a valid ID in a convex function and handle the case where it's not on the client Here's a snippet of what that second approach might look like:

const getGame = query({
    args: { gameIdString: v.string()},
    handler: async(ctx, { gameIdString }) => {
        const gameId = ctx.db.normalizeId("game", gameIdString)

        if (gameId === null) {
            // Client can redirect to home page or similar
            return { result: "Game not found" }
        }
        const game = await ctx.db.get(gameId);
        // ...
    }
})

const getGame = query({
    args: { gameIdString: v.string()},
    handler: async(ctx, { gameIdString }) => {
        const gameId = ctx.db.normalizeId("game", gameIdString)

        if (gameId === null) {
            // Client can redirect to home page or similar
            return { result: "Game not found" }
        }
        const game = await ctx.db.get(gameId);
        // ...
    }
})
