Question

我理解不应该采用深层嵌套资源，但我不知道如何将其正确转换为1级嵌套资源。如果存在干净的教程，请向我展示教程，我将学习它。如果没有那么请帮我解决我的问题。这是我的route.rb

resources :article do
  resources :picture
  resources :comments do
    resources :repcomments
  end
end
resources :reports

我可以做文章，图片，评论但不确定如何处理第三级报告。我们的想法是，文章可以有评论，评论可以在哪里报告给管理层。 Everythings在文章#show pages和here

中播放

  def show
    @art = Article.find(params[:id])
    @comments = @art.comments.find(:all, :order => 'created_at DESC')
    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @art }
    end
  end

这里是文章#show中的视图表单

<%= @art.title %>
<%= @art.content %>
Comment
<%= form_for [@art, current_customer.comments.new] do |f| %>
  <%= f.text_area :description %><br />
  <%= f.submit "Add Comment" %>
<% end %>
# End of form comments
<% @comments.each do |comment| %>
  <%= comment.description %>
  <div>Report</div>
  <%= form_for [@art, comment, repcomments.new] do |f| %>
    <%= f.text_area :body %><br />
    <%= f.submit "Report it" %>
  <% end %> 
<% end %>

我得到一个没有定义方法而不确定如何处理它。提前致谢

这里是路线文件

 article_comment_repcomments GET    /articles/:article_id/comments/:comment_id/repcomments(.:format)          repcomments#index
                              POST   /articles/:article_id/comments/:comment_id/repcomments(.:format)          repcomments#create
 new_article_comment_repcomment GET    /articles/:article_id/comments/:comment_id/repcomments/new(.:format)      repcomments#new
edit_article_comment_repcomment GET    /articles/:article_id/comments/:comment_id/repcomments/:id/edit(.:format) repcomments#edit
     article_comment_repcomment GET    /articles/:article_id/comments/:comment_id/repcomments/:id(.:format)      repcomments#show
                              PUT    /articles/:article_id/comments/:comment_id/repcomments/:id(.:format)      repcomments#update
                              DELETE /articles/:article_id/comments/:comment_id/repcomments/:id(.:format)      repcomments#destroy

这里的模型

class Repcomments < ActiveRecord::Base
  belongs_to :customer
  belongs_to :article
  attr_accessible :acknowledged, :body, :completed, :customer_id, :article_id
end

这里我的控制器重新命名

class RepcommentsController < ApplicationController
  # GET /repcomments
  # GET /repcomments.json
  def index
    @article = Article.find(params[:article_id])
    @comments = @articles.comments.find(params[:comment_id])
    @repcomments = Repcomment.all

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @repcomments }
    end
  end

  # GET /repcomments/1
  # GET /repcomments/1.json
  def show
    @article = Article.find(params[:article_id])
    @comments = @articles.comments.find(params[:comment_id])
    @repcomment = Repcomment.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @repcomment }
    end
  end

  # GET /repcomments/new
  # GET /repcomments/new.json
  def new
    @article = Article.find(params[:article_id])
    @comments = @articles.comments.find(params[:comment_id])
    @repcomment = Repcomment.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @repcomment }
    end
  end

  # GET /repcomments/1/edit
  def edit
    @article = Article.find(params[:article_id])
    @comments = @articles.comments.find(params[:comment_id])
    @repcomment = @comments.repcomments.find(params[:id])
  end

  # POST /repcomments
  # POST /repcomments.json
  def create
    @article = Article.find(params[:article_id])
    @comments = @articles.comments.find(params[:comment_id])
    @repcomment = @comments.repcomments.build(params[:repcomment])

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

  # PUT /repcomments/1
  # PUT /repcomments/1.json
  def update
    @article = Article.find(params[:article_id])
    @comments = @articles.comments.find(params[:comment_id])
    @repcomment = @comment.repcomments.find(params[:id])

    respond_to do |format|
      if @repcomment.update_attributes(params[:repcomment])
        format.html { redirect_to @repcomment, notice: 'Repcomment was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: @repcomment.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /repcomments/1
  # DELETE /repcomments/1.json
  def destroy
    @article = Article.find(params[:article_id])
    @comments = @articles.comments.find(params[:comment_id])
    @repcomment = @comments.repcomments.find(params[:id])
    @repcomment.destroy

    respond_to do |format|
      format.html { redirect_to repcomments_url }
      format.json { head :no_content }
    end
  end
end

几乎就是这样

只需查看您的代码，我就可以在您的路线中看到一个问题：:article和:picture需要是复数。

resources :articles do
    resources :pictures
    resources :comments do
        resources :repcomments
    end
end
resources :reports

此外，您无需在:repcomments内嵌套:articles。除了路线中已有的内容，您还可以添加：

resources :comments do
    resources :repcomments #and remove the other "resources :repcomments"
end

是的，您将resources :comments定义两次，但没关系。

如果您从未对文章范围之外的评论做任何事情，那么您可以编写您的路线：

resources :comments, only: [] do
    resources :repcomments
end

这样Rails就不会生成默认的休息路由（没有/评论，没有/评论/：id等）
