Creating a User when one does not exist

[StevenClontz]

Many users of my app will only use it once or twice a year, and likely won't even remember if they have a User or not. I'd like to have a pattern where they provide their email, and then they either enter the token or click the magic link sent to their email, and once that's done, either they are logged into their existing User, or a User is created for them. Has anyone used passwordless for such an approach?

Ah, it just clicked that the example at https://github.com/mikker/passwordless?tab=readme-ov-file#looking-up-the-user does exactly this.

class User < ApplicationRecord
  def self.fetch_resource_for_passwordless(email)
    find_or_create_by(email: email)
  end
end

Yes, the suggested approach is to just roll your own logic. Use the ControllerHelpers if you'd like 😊
