Redirect from sign in pages when already signed in

[StevenClontz]

Is there a slick way I can redirect from /users/sign_in to / (or wherever) when the user is already authenticated?

You could do with a before_action filter i ApplicationController or maybe a route constraint or you could write your own SessionsController#new controller/action.

Thanks! I ended up going this route:

# config/routes.rb
passwordless_for :users, controller: "sessions"

# app/controllers/sessions_controller.rb

class SessionsController < Passwordless::SessionsController
  before_action :require_unauth!, only: %i[ new show ]

  private

    def require_unauth!
      unless @current_user.nil?
        redirect_to "/", notice: "You are already signed in."
      end
    end
end

unauth 😅 Looks like a good solution! Thank you for contributing it back to the project

No problem! This gem has done exactly what I hoped it would for my own project, so thank you.
