I have a Rails 6 app, where I am upgrading some functionalities and upgrading the API version to v2. There are older clients out there that are using the v1 API versions. For all these, I have to change the incoming url in v1 to v2.

Example, a request comes in at /api/v1/users, I want it to change to /api/v2/users.

I've tried few things like using redirect in routes.rb file, like the ones suggested in API Versioning for Rails Routes. However, I could not get it too work.

My routes.rb file contains something like this:

Rails.application.routes.draw do
 namespace 'ads' do
  get '/fingerprint' => 'fingerprint#index'
 end

 namespace 'api' do
   scope '/v2' do
     ...
   end
 end

end

I'd like to add something like

namespace 'api' do

   scope '/v1' do
     # redirect to v2 version of the url 
   end

   scope '/v2' do
     ...
   end
 end

I'd like to fix it within the Rails app, but I guess fixing at Apache is also an option. I'm open to any sorts of solutions. Thanks.
