Getting current user id in mutation
Hi!
I'm trying to post a comment related to defined item. I pass itemId as an argument but i want to use current user's id as a comment author.
I've configured simple password login. I could see in database that fields i used in withIndex are equal but i couldnt pass identity.subject as is as it is not Id<users> field. thus query returns empty array.
How to do this correctly? Should I use users collection instead of authAccounts?
export const add = mutation({
args: {
text: v.string(),
itemId: v.id('items'),
},
handler: async (ctx, args) => {
const identity = await ctx.auth.getUserIdentity();
if (!identity) {
throw new Error('Not authenticated');
}
const user = await ctx.db
.query('authAccounts')
.withIndex('userIdAndProvider', (q) => q.eq('userId', identity.subject as Id<'users'>))
.first();
if (!user) {
throw new Error('User not found');
}
const comment = await ctx.db.insert('comments', {
text: args.text,
itemId: args.itemId,
userId: user.userId,
createdAt: Date.now(),
});
return comment;
},
});3 Replies

How to do this correctly? Should I use users collection instead of authAccounts?Yes, since you're trying to link a user to this comment, not an auth account @Marcin check out
getUserAuthId as used in https://github.com/get-convex/convex-auth/blob/main/test/convex/users.ts
I could see in database that fields i used in withIndex are equal but i couldnt pass identity.subject as is as it is not Id<users> field. thus query returns empty array.To see how to do this, check out the source for that function https://github.com/get-convex/convex-auth/blob/10b4924e0b8e0a97d2130c01eaf02c8dd2b25fb6/src/server/implementation/index.ts#L463-L470
Oh i see. Thats so simple now! 🙂
Thank you
