spree에 사용자 정의 모델 추가 및 오류 발생 : 초기화되지 않은 상수 Admin

Question

사용자 설정 사진 모델을 연속 판매 관리자 패널에 추가하려고하는데 페이지로 이동하려고 할 때 오류가 발생했습니다. 초기화되지 않은 상수 관리자입니다. 나는 그것이 내 파일의 이름을 짓는 방법 또는 내가 그들을 두는 곳과 관련이 있다는 느낌이 들었다.

경로

namespace :admin do 
    resources :photos 
end 

내보기 파일이 모두있는

: 응용 프로그램/뷰/마구/관리/사진

응용 프로그램/컨트롤러/관리/photos_controller.rb 이것은 내가 지금까지 무엇을 가지고

전체 오류입니다

Answer 1

당신은 사용할 필요가 :

class PhotosController < BaseController 

당신이 admin 네임 스페이스 이미

Answer 2

잘 내부에 있기 때문에, 당신은 당신을 도울 것입니다 적절한 모듈 scoping.This 코드를 사용해야합니다.

module Spree 
    module Admin 
    class PhotosController < BaseController 
     before_action :set_photo, only: [:show, :edit, :update, :destroy] 

     # GET /photos 
     # GET /photos.json 
     def index 
     @photos = Photo.all 
     end 

     # GET /photos/1 
     # GET /photos/1.json 
     def show 
     end 

     # GET /photos/new 
     def new 
     @photo = Photo.new 
     end 

     # GET /photos/1/edit 
     def edit 
     end 

     # POST /photos 
     # POST /photos.json 
     def create 
     @photo = Photo.new(photo_params) 

     respond_to do |format| 
      if @photo.save 
      format.html { redirect_to @photo, notice: 'Photo was successfully created.' } 
      format.json { render :show, status: :created, location: @photo } 
      else 
      format.html { render :new } 
      format.json { render json: @photo.errors, status: :unprocessable_entity } 
      end 
     end 
     end 

     # PATCH/PUT /photos/1 
     # PATCH/PUT /photos/1.json 
     def update 
     respond_to do |format| 
      if @photo.update(photo_params) 
      format.html { redirect_to @photo, notice: 'Photo was successfully updated.' } 
      format.json { render :show, status: :ok, location: @photo } 
      else 
      format.html { render :edit } 
      format.json { render json: @photo.errors, status: :unprocessable_entity } 
      end 
     end 
     end 

     # DELETE /photos/1 
     # DELETE /photos/1.json 
     def destroy 
     @photo.destroy 
     respond_to do |format| 
      format.html { redirect_to photos_url, notice: 'Photo was successfully destroyed.' } 
      format.json { head :no_content } 
     end 
     end 

     private 
     # Use callbacks to share common setup or constraints between actions. 
     def set_photo 
      @photo = Photo.find(params[:id]) 
     end 

     # Never trust parameters from the scary internet, only allow the white list through. 
     def photo_params 
      params.require(:photo).permit(:image, :book_id) 
     end 

     end 
    end 
    end 
end 

또한, 나는 ResourceController 대신 BaseController에서 클래스를 상속을 추천 할 것입니다. 이렇게하면 LOC를 절약 할 수 있고 정말 도움이 될 것입니다.
