How do I make a before_action to run on all controllers and actions except one?
What you have to do is to set autheticate_user! on all controllers like that :
class ApplicationController < ActionController::Base before_action :authenticate_user! ...endAnd then on your HomeController you do that :
class HomeController < ApplicationController skip_before_action :authenticate_user!, only: [:index] ...endHope this will help you !
You can use params[:controller] to detect controller name of request.
class ApplicationController < ActionController::Base before_action :authenticate_user! AUTHENTICATE_USER_EXCEPT_CONTROLLERS = ['controller_names_you_want_to_exclude'] ... def authenticate_user! unless AUTHENTICATE_USER_EXCEPT_CONTROLLERS.include?(params[:controller]) super end endend
