Rails Routes 네임 스페이스 및 form_for

Rails Routes 네임 스페이스 및 form_for

---

내 route.rb에 네임 스페이스가 있습니다.

  namespace :businesses do
    resources :registration
  end

내 컨트롤러는 business / registration_controller 하위 디렉토리에 있습니다.

def new
  @business = Business.new
end

제 생각에는 이렇게하고 싶지만 form_for @business do |f| ...다음과 같은 오류가 발생합니다.

No route matches {:controller=>"businesses", :action=>"create"}

서버를 다시 시작했는데 다음과 같은 결과도 나타납니다.

undefined method# <# : 0x10339bb20>`에 대한 business_path '

내 레이크 루트는 다음과 같습니다.

네임 스페이스 경로가있는 경우 가장 좋은 방법은 다음과 같습니다.

class Admin::BusinessesController < ApplicationController
  def new
    @business = Business.new
  end
end

route.rb에서 :

namespace :admin do
  resources :businesses
end

보기 :

form_for [:admin, @business] do |f|...

문서 : http://guides.rubyonrails.org/form_helpers.html 섹션 2.3.1 네임 스페이스 다루기

귀하의 경우 :

route.rb에서는 모든 것이 정상입니다. 컨트롤러에 컨트롤러 이름이 아닌 변수가 있으므로 뷰에서 명시 적으로 URL을 작성해야합니다.

form_for @business, :url => business_registration_path do |f|...

business / registration_controller에 다음과 같은 것이 있다고 가정합니다.

class Businesses::RegistrationController < ApplicationController
  def new
    @business = Business.new
  end
end

And one remark: I wouldn't create registration_controller for registering a new business. I think that keeping business related actions in business_controller is much clearer.

Actually, I think there is a better solution.

form_for [:admin, @business]

the issue with giving a url is that if you abstract the form out as a partial view, you'll need to deal with "create" and "update" situations. They points to different urls, and ends up with providing the @url in controller.
