"userId" as id of user instead of "id"

I want to implement BetterAuth inside an existing application, but the user model has user.userId field as the id, but I see BetterAuth requires it to be user.id is it possible to change this or should I make an additional column for the better auth id?

Solution:

We don't allow custom id names yet. @IceeCold It may be a future we add later down the line however....

You should be able to just use custom table names to remap it;

export const auth = betterAuth({
  user: {
    modelName: "users",
    fields: {
      id: "userId",
    },
  }
});

export const auth = betterAuth({
  user: {
    modelName: "users",
    fields: {
      id: "userId",
    },
  }
});

Ahh... That might be tricky. If they don't allow you to remap id, then it's probably for a good reason.
