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?

Solution 1

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

Solution 2

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

Solution 3

Haven't tried but add this in your ApplicationController:

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

Solution 4

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

Solution 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

This is a site that mixes http and https a lot though, I think that would make all the URLs https (right?)

[apneadiving]

yes, you're right, so you should only put this in the controllers having https

[Joe Van Dyk]

Still not sure how that helps me. If I'm on a http page, I want test_url() to return a https URL, not a http one.

[apneadiving]

ok, sorry about that. Remark: giving -1 to people trying to help you won't serve your cause.

[Joe Van Dyk]

That doesn't have anything to do with generating URLs.

[Ross]

In this case you generate your urls as normal, but its is submitted as SSL for the methods that you have mentioned

[Joe Van Dyk]

No, it's not. It will redirect the http post from http to https, losing the post data.

Although this code may help to solve the problem, it doesn't explain why and/or how it answers the question. Providing this additional context would significantly improve its long-term value. Please edit your answer to add explanation, including what limitations and assumptions apply.

Probably things changed, this no longer works in 5.1.4. See stackoverflow.com/a/48781000/474597
