Upgrading to Rails 5.1

[uksa]

This is the best CMS library I've used and I've tried a few out. however :( after an effort to try and upgrade it to use Rails 5.1 I've sadly not been able to manage it.

If someone out there has managed it or wouldn't mind giving me a few pointers, I might be able to complete the job and would massively appreciate it!

The problem, once I finally removed all of the dependencies, seems to be around url_for_patch. alias_method_chain is no longer allowed in Rails 5.1

module ActionDispatch
  module Routing
    class RouteSet

      if Rails::VERSION::MINOR >= 2
        def url_for_with_storytime(options, route_name = nil, url_strategy = UNKNOWN)
          Storytime::PostUrlHandler.handle_url(options)
          url_for_without_storytime(options, route_name, url_strategy)
        end
      else
        def url_for_with_storytime(options = {})
          Storytime::PostUrlHandler.handle_url(options)
          url_for_without_storytime(options)
        end
      end

      alias_method_chain :url_for, :storytime

    end
  end
end

This is where I started, however I'm unable to quite get my head around how the with/without method call get substituted with the code below.

module RouteSetWithURLForStorytime
  def url_for(options={})
    Storytime::PostUrlHandler.handle_url(options)
    super(options)
  end

end

RouteSet.send(:prepend, RouteSetWithURLForStorytime)

Any help would be really appreciative.

btw: I used the following article as my inspiration to fix the issues.
