Rails initializer that runs *after* routes are loaded?

Question

I want to set a class attribute when my Rails app starts up. It requires inspecting some routes, so the routes need to be loaded before my custom code runs. I am having trou

Answer 1

If you're trying to run code in an initializer after the routes have loaded, you can try using the after: option:

initializer "name_of_initializer", after: :add_routing_paths do |app|
  # do custom logic here
end

You can find initialization events here: http://guides.rubyonrails.org/configuring.html#initialization-events

Answer 2

You can force the routes to be loaded before looking at Rails.application.routes with this:

Rails.application.reload_routes!

So try this in your config/application.rb:

config.after_initialize do
  Rails.application.reload_routes!
  Rails.logger.info "#{Rails.application.routes.routes.map(&:path)}"
end

I've done similar things that needed to check the routes (for conflicts with /:slug routes) and I ended up putting the reload_routes! and the checking in a config.after_initialize like you're doing.
