Doing a Http basic authentication in rails

Question

Hi I\'m from Grails background and new to Rails. I wish to do http basic authentication in rails.

I have a code in grails which does basic authentication like this:<

Answer 1

# app/controllers/application_controller.rb
  before_filter :http_basic_auth

  def http_basic_auth
    if ENV['HTTP_AUTH'] =~ %r{(.+)\:(.+)}
      unless authenticate_with_http_basic { |user, password|  user == $1 && password == $2 }
        request_http_basic_authentication
      end
    end
  end

and then you just need to export your environment variable with the user:password for example:

   export HTTP_AUTH=user:pass

if you are using heroku.com:

   heroku config:set HTTP_AUTH=user:pass
