SSL with Ruby on Rails

Question

What do I need to do to get traffic to my ruby on rails app to use https? I have a certificate installed and if I manually type in \"https://\" in the address bar when accessin

Answer 1

Check out the ssl_requirement gem.

It lets you specify in your controllers which actions should be served over https and which actions can be served over https. It will then take care of redirecting from http to https and vice-versa.

From the documentation:

class ApplicationController < ActiveRecord::Base
  include SslRequirement
end

class AccountController < ApplicationController
  ssl_required :signup, :payment
  ssl_allowed :index

  def signup
    # Non-SSL access will be redirected to SSL
  end

  def payment
    # Non-SSL access will be redirected to SSL
  end

  def index
    # This action will work either with or without SSL
  end

  def other
    # SSL access will be redirected to non-SSL
  end
end

Ruby on Rails is an application framework and not a web server. The HTTPS configuration you need to change is in your web server (Apache, nginx, etc) config.

Answer 3

It's pretty easy, and you don't need a gem for it. I blogged how to redirect without www in rails here. Redirecting to https is (almost) exactly the same.

class ApplicationController < ActionController::Base
  before_filter :redirect_to_https

  def redirect_to_https
    redirect_to "https://example.com#{request.fullpath}" if !request.ssl? && request.host != "localhost"
  end
end

Apply your before_filter on anything that you want to make sure is kept behind the SSL security. I'm usually one for code reuse and gems, but this one is ridiculously simple. Read more about request.protocol. (Note that in the Ruby 1.9.3 / Rails 3.2 environment, the name is request.fullpath; in some earlier versions, it was request.request_uri; see the release notes, etc.)
