Getting Rails URL helpers to automatically output https urls

Question

I am developing a site that mixes http and https a lot - whats the best/easiest way to make the links use the right protocol for the route - can it be specified in the routes file?

Say I have the following route in Rails 3.

match "/test" => "test#index", :as => :test, :constraints => { :protocol => 'https' }

If I'm on a http page, and I use test_url(), it'll output http://domain.com/test. I want https://domain.com/test instead.

I know I can use test_url(:secure => true), but that's duplicating logic.

I know I could have http://domain.com/test to https://domain.com/test, but that's an extra redirect, plus it fails on form posts.

Ideas?

Answer 1

Use test_url(:protocol => 'https') for https urls.

Answer 2

Haven't tried but add this in your ApplicationController:

def default_url_options(options={})
 { :secure => true }
end 

Answer 3

def default_url_options(options={})
 { :protocol => "https" }
end

Answer 4

It looks like this will be solved in Rails 4! https://github.com/rails/rails/commit/9b4514c3b8ecfbc40a44dbd4c2ebd4ce67f4a459

Answer 5

For Rails 3.2 I used a combination of @apneadiving's answer. Adding the below code to my ApplicationController

def default_url_options(options={})
  options.merge{ :protocol => "https" }
end

Answer 6

Rails 3 SSL routing redirects from https to http answers this question pretty well. In short, there's not a great way to do it. I submitted the following Rails bug: https://github.com/rails/rails/issues/3571

You can use a plugin called ss_requirement, it will provide you with methods like ssl_required ssl_allowed

You can simply add this in your controller to enable ot disable https on any action

ssl_allowed :login, :update_profile
