沒有路線匹配缺少必需的鍵：[object_id]

Question

我在我的應用程序中有幾個嵌套的路線。我正在建立一個數據庫，根據他們所處的行業以及該行業內的各種競爭對手對初創公司進行分類。

我一直在尋找這個問題的答案錯誤，但我有麻煩想出來的：

編輯添加完整的錯誤信息和categories_controller.rb

錯誤消息：

ActionController::UrlGenerationError in Categories#show 

No route matches {:action=>"edit", :controller=>"categories", :id=>"5", :industry_id=>nil} missing required keys: [:industry_id] 

嵌套路線： 個資源：行業中，只有：[：秀：創建，編輯，：更新]做 資源：類別做 資源：啓動，模塊：類別
端 端

Category.rb 

class Category < ActiveRecord::Base 
    has_many :startups, as: :startupable 
    belongs_to :industry 
    belongs_to :user 
end 


Industry.rb 

class Industry < ActiveRecord::Base 
    belongs_to :user 
    has_many :categories 
end 

startup.rb 

class Startup < ActiveRecord::Base 
    belongs_to :startupable, polymorphic: true 
    belongs_to :user 
end 

Ç

ategories_controller.rb 

class CategoriesController < ApplicationController 
    before_action :set_category, only: [:show, :edit, :update, :destroy] 
    respond_to :html 

    def index 
    @categories = Category.all.order("created_at DESC").paginate(:page => params[:page], :per_page => 3) 
    authorize @categories 
    end 

    def show 
    end 


    def new 
    @industry = Industry.find(params[:industry_id]) 
    @category = @industry.categories.new 
    flash[:notice] = "Category created." 
    authorize @category 
    end 


    def edit 
    end 


    def create 
    @industry = Industry.find(params[:industry_id]) 
    @category = current_user.categories.build(category_params) 
    respond_with @industry 
    authorize @category 
    end 


    def update 
    respond_to do |format| 
     if @category.update(category_params) 
     format.html { redirect_to @category, notice: 'Category was successfully updated.' } 
     format.json { render :show, status: :ok, location: @category } 
     else 
     format.html { render :edit } 
     format.json { render json: @category.errors, status: :unprocessable_entity } 
     end 
    end 
    end 


    def destroy 
    @category.destroy 
    redirect_to @industry 
    flash[:notice] = "You have succesfully deleted the category." 
    end 

    private 
    def set_category 
     @category = Category.find(params[:id]) 
     authorize @category 
    end 
    def correct_user 
     @category = current_user.categories.find_by(id: params[:id]) 
     redirect_to categories_path, notice: "Not authorized to edit this Category" if @category.nil? 
    end 

    def category_params 
     params.require(:category).permit(:name) 
    end 
end 

出於某種原因，擊中視圖按鈕或我的類別不與他們的行業關聯適當的時候我不調用Industry_id。

有什麼建議嗎？

Answer 1

show.html.erb

UPDATE

<%= link_to "Edit", edit_industry_category_path(@category.industry, @category) %>
