Question

我无法在我的控制器中使用我的销毁操作来工作。我已经读过您必须包含要删除的默认JavaScript库，但我已经完成了（至少我认为我有），但它仍然无法正常工作。我的应用程序背景：文章是＆＃34;食谱＆＃34;，所以我的控制器叫做recipes_controller。这是我的recipes_controller中的代码：

class RecipesController < ApplicationController
  before_action :authenticate, except: [:index, :show]
  before_action :set_recipe, only: [:show, :edit, :update, :destroy]

  # GET /recipes
  # GET /recipes.json
  def index
    @recipes = Recipe.all
  end

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

  # DELETE /recipes/1
  # DELETE /recipes/1.json
  def destroy
    @recipe.destroy
    respond_to do |format|
      format.html { redirect_to recipes_url, notice: 'Recipe was  
      successfully destroyed.' }
      format.json { head :no_content }
    end
  end

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

  # Never trust parameters from the scary internet, only allow the white list through.
  def recipe_params
    params.require(:recipe).permit(:title, :body, :published_at, :category_ids => [])
  end
end

然后，这是我的application.html.erb文件的代码，我认为我已经包含了默认的javascript库：

<html>
<head>
<title>inherentlydope</title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag :defaults %>d
<%= csrf_meta_tag %>
</head>
<body>

<%= content_tag :p, notice, :class => 'notice' if notice.present? %>
<%= content_tag :p, alert, :class => 'alert' if alert.present? %>

<%= yield %>

</body>
</html>

然后，这是我的routes.rb文件：

Rails.application.routes.draw do

  root to: "recipes#index"
  #resources :comments
  resources :recipes do
    resources :comments
  end
  resources :users
  resource :session, only: [:new, :create, :destroy] #always deal with session, not sessionS
  get '/login' => "sessions#new",as: "login"
  get '/logout' => "sessions#destroy", as: "logout"
end

在控制器中销毁操作不起作用
