Finding routes path from url string

Question

I want to know what is the route of api request.

Lets say for example api_v1_user_session_path is the route for /api/v1/users/sign_in url

If a request is coming from /api/v1/users/sign_in How can I find out what is the route. In this scenario it should be api_v1_user_session_path

I tried below statement but it is giving controller and action but not route.

Rails.application.routes.recognize_path('/api/v1/users/sign_in')
=> {:controller=>"api/v1/sessions", :action=>"new"}

Is there any method like this

Rails.application.routes.get_route('/api/v1/users/sign_in')
=> api_v1_user_session

How can I get this route from url or from request object.

Answer 1

With more search I was able to figure it myself.

class StringToRoute

  attr_reader :request, :url, :verb

  def initialize(request)
    @request = request
    @url = request.original_fullpath
    @verb = request.request_method.downcase
  end

  def routes
    Rails.application.routes.routes.to_a
  end

  def recognize_path
    Rails.application.routes.recognize_path(url, method: get_verb)
  end

  def process
    _recognize_path = recognize_path
     routes.select do |hash|
       if hash.defaults == _recognize_path
         hash
       end
     end
  end

  def get_verb
    verb.to_sym
  end

  def path
    "#{verb}_#{process.name}"
  end
end

Result:

StringToRoute.new(request).path
