Ruby on Rails，命名路线

Question

So for example i have non-restful named route:

get ':controller/:action/:juhu/:blabla', :as => "something"

and from rake routes i have following:

Prefix Verb URI Pattern                                  Controller#Action
something GET /:controller/:action/:juhu/:blabla(.:format) :controller#:action

//Controller

class TestsController < ApplicationController
    def juhu_juhu
        # Will try to render juhu_juhu.html.erb
    end
end

// View

    <%= link_to "Get back", something_path %>

And i get error:

No route matches {:juhu=>"1", :blabla=>"neta", :controller=>"tests", :action=>"juhu_juhu"} missing required keys: [:id]

So what about this "missing required keys: [:id]"

So i assume that every restful routes must have :id by convention(am i right?), but why non-restful routes also must have :id (literally named :id), or something i'm doing wrong here?

Answer 1

What is your rails version?

routes.rb

root 'tests#index'
get ':controller/:action/:juhu/:blabla', :as => "something"

index.html.erb

<%= link_to "Get back", something_path %>

tests_controller.rb

class TestsController < ApplicationController
  def index
  end

  def juhu_juhu
  end
end

I try you example and I got this problem and check 127.0.0.1:3000 .

No route matches {:action=>"index", :controller=>"tests"} missing required keys: [:juhu, :blabla]

The url 127.0.0.1:3000/tests/juhu_juhu/1/2 is success and could not have "missing required keys: [:id]" problem.

And I link to 127.0.0.1:3000/tests/juhu_juhu/1/neta also success:

Started GET "/tests/juhu_juhu/1/neta" for 127.0.0.1 at 2013-11-01 00:48:23 +0800
