Question

我的rails 4应用程序中有一个名为Article的模型。

我想在我的views / articles文件夹中添加一个名为foldaway.html.erb的静态页面。

我添加了该视图页面，并使用以下内容更新了我的文章控制器：

def foldway
end

我还试图从set_article方法中排除foldaway：

before_action :set_article, except: [:foldway], only: [:show, :edit, :update, :destroy ]

在我的路线文件中，我添加了：

  get '/foldway' => 'articles#foldway'

当我保存所有这些并尝试测试页面是否呈现时，我收到一条错误消息：

Couldn't find Article with 'id'=foldway

当我从rails控制器中的set_article方法中排除它时，为什么要设置文章ID。我只是想让它呈现一个静态页面。

如何将其添加到我的文件中？

我的完整文章控制器是：

class ArticlesController < ApplicationController
  before_action :set_article, except: [:foldway], only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, except: [:index, :show ]
  layout "article"

  respond_to :html, :json
# GET /articles
  # GET /articles.json
  def index
    @articles = policy_scope(Article)
    # query = params[:query].presence || "*"
    # @articles = Article.search(query)
  end

  # def index
  #   if params[:query].present?
  #     @books = Book.search(params[:query], page: params[:page])
  #   else
  #     @books = Book.all.page params[:page]
  #   end
  # end

  # GET /articles/1
  # GET /articles/1.json
  def show

  end

  def foldway
  end

  # GET /articles/new
  def new
    @article = Article.new
    @article.comments.build
  end

  # GET /articles/1/edit
  def edit

    authorize @article
  end

  # POST /articles
  # POST /articles.json
  def create
    # before_action :authenticate_user!
    # authorize @article
    @article = current_user.articles.new(article_params)

    respond_to do |format|
      if @article.save
        format.html { redirect_to(@article) }
        format.json { render :show, status: :created, location: @article }
      else
        format.html { render :new }
        format.json { render json: @article.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /articles/1
  # PATCH/PUT /articles/1.json
  def update
    # before_action :authenticate_user!
    authorize @article
    respond_to do |format|
    #   if @article.update(article_params)
    #     format.json { render :show, status: :ok, location: @article }
    #   else
    #     format.html { render :edit }
    #     format.json { render json: @article.errors, status: :unprocessable_entity }
    #   end
    # end
      if @article.update(article_params)
         format.html { redirect_to(@article) }
        format.json { render :show, status: :ok, location: @article }
      else
        format.json { render json: @article.errors, status:      :unprocessable_entity }
      end
      format.html { render :edit }
    end
  end



  # DELETE /articles/1
  # DELETE /articles/1.json
  def destroy
    before_action :authenticate_user!
    authorize @article
    @article.destroy
    respond_to do |format|
      format.json { head :no_content }
    end
  end


  private
    # Use callbacks to share common setup or constraints between actions.
    def set_article
      @article = Article.find(params[:id])
      authorize @article
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def article_params
      params.require(:article).permit(:body, :title, :image, :tag_list,
        comment_attributes: [:opinion])
    end

end

Answer 1

问题来自您的路线文件。

我建议你把它放在routes.rb文件中：

get 'articles/foldway' => 'articles#foldway', as: :foldway

match '/foldway', to: 'articles#foldway', via: :get

对于您的文章控制器，您只需要输入：

before_action :set_article, only: [:show, :edit, :update, :destroy ]
