Question

I’m making a simple blog to learn rails.

Everything is almost finished, and I’m trying to apply HTTP authentication, as outlined here –> http://berk.es/2011/03/29/simplest-authentication-in-rails-basic-authentication-with-a-logged_in-helper/

My authentication code looks like this, in the ApplicationController

class ApplicationController < ActionController::Base
  protect_from_forgery

  protected
    def authenticate
      authenticate_or_request_with_http_basic do |username, password|
        username == ADMIN_ID && password == ADMIN_PASSWORD
      end
    end
end

instead of passing the variable in my files, however, I want to pass it through heroku. So I ran –>

heroku config:add ADMIN_ID=myusername
heroku config:add ADMIN_PASSWORD=mypassword

When I tried logging in though I get a “Something went wrong” message. Here’s what heroku logs say :

From the looks of it, I think the environment variables I passed don’t seem to be detected. What do you suggest I do?

Answer 1

You should access them as ENV['ADMIN_ID'] and ENV['ADMIN_PASSWORD']
