# [Quicky] Unused routes for Rails 7.0 below

With [Rails 7.1](https://github.com/rails/rails/pull/45701), you can list unused routes with:

```plaintext
./bin/rails routes --unused
```

For Rails 6.0, 6.1 and 7.0, below is a script I used in my project to find out unused routes. Apparently, I barrow it from [ShakaCode](https://www.shakacode.com/blog/identify-unused-routes-in-rails-7/). Thanks to them.

In conjunction with the [self contained rails script shown before](https://blog.brennetot.com/quicky-self-contained-rails-script), here's the full modified script:

```ruby
#!/usr/bin/env ruby
APP_PATH = File.expand_path("../../config/application",  __FILE__)
require File.expand_path("../../config/boot",  __FILE__)
require APP_PATH

Rails.application.require_environment!

unused_routes = {}

Rails.application.routes.routes.each do |r|
  name = r.requirements[:controller].to_s.camelize
  action = r.requirements[:action].to_s
  controller = "#{name}Controller"

  if Object.const_defined?(controller) && !controller.constantize.new.respond_to?(action)
    unless Dir.glob(Rails.root.join("app", "views", name.downcase, "#{action}.*")).any?
      unused_routes[controller] = [] if unused_routes[controller].nil?
      unused_routes[controller] << action
    end
  end
end

pp unused_routes
```

The script is in the file `bin/unused_routes`. And it's an executable (`chmod +x bin/unused_routes`).

With that, you only need to run the command below. No more need to remember or search for it, everything lives in your repository.

```plaintext
./bin/unused_routes
```

### Magical!
