编辑ruby on rails评论时的路由错误博客

Question

我的应用工作正常，直到我决定添加评论的编辑功能。在此之前，我可以查看特定的文章，但不是现在。我在评论视图中添加了edit.html.erb页面，并且_comment_form.html.erb为partial.Now我无法访问文章/ 12（例如），当我尝试时，它说No route matches {:action=>"edit", :controller=>"comments", :article_id=>#<Article id: 21, title: "good for health", body: "uby on Rails 3 Model Data Validation\r\nRails Model D...", created_at: "2013-04-14 15:14:19", updated_at: "2013-04-24 05:51:20", user_id: 1, impressions_count: 7>, :id=>#<Comment id: nil, content: nil, user_id: nil, article_id: 21, created_at: nil, updated_at: nil>}

基本上，我试图在文章/展示页面上实现评论编辑功能。为此，我在评论视图下添加了edit.html.erb。但现在没有任何工作。任何建议都会升值。

comments_controller.rb

class CommentsController < ApplicationController 
    before_filter :user_signed_in, except: [:create] 
    def new 
     @comment = Comment.new 
    end 

    def create 
     @article = Article.find(params[:article_id]) 
     @comment = @article.comments.build(params[:comment]) 
     @comment.user_id = current_user.id 
     @comment.save 
     flash[:success] = "Comment created!" 
     redirect_to article_path(@comment.article) 
    end 

    def edit 
    @comment = Comment.find(params[:id]) 
    end 

    def update 
    @comment = Comment.find(params[:id]) 
    @article = @comment.article 
    respond_to do |format| 
     if @comment.update_attributes(params[:comment]) 
     redirect_to @article_path(@article) 
     else 
     render :action => "edit" 
     end 
    end 

    def destroy 
    @comment = Comment.find(params[:id]) 
    @article = Article.find(params[:article_id]) 
    @comment.destroy 
     redirect_to @article_path(@artilce) 
    end 

end 

评论/ edit.html.erb

<h3>Editing comment</h3> 
<%= render :partial => 'comment_form' %> 

评论/ _comment_form.html.erb

<%= form_for ([@article, @article.comments.build]), :required => true do |f| %> 
<%= f.hidden_field :article_id %> 
<%= f.text_area :content, :style => "width:727px; height:100px; border: 1px solid #999999;margin-top:80px; background-color:#FFFFFF;margin-left:-33px" %> 
    <div class="actions"> 
    <%= f.submit "Add Comment", :style => "margin-right:20px; margin-left:560px; background-color:#66C9Ef; color:#FFFFFF; border: 0px solid #82b548; border-radius: 3px 3px 3px 3px; font-size: 1.3rem;" %> 
    </div> 
<% end %> 

评论/ comment.html.erb（在这里我已经给出了编辑评论文章的链接）

      <ul id="tabula"> 
      <li> <div style="color: #0077CC;margin-rigth:200px; font-size: 1.0em;margin-top:4px;background-color:#;"> <%= comment.user.username if comment.user %></div></li>

      </ul> 
      </div> 
      </div> 
    <% else %> 
     <div style="color:#0077CC;margin-left:25px;font-size:1.4em;"> be first to comment</div> 
    <% end %>

注：当我访问了一篇文章不有意见，它的工作原理，但是当我尝试访问有评论的文章，​​它显示上面的路由错误。任何建议都会升值。

Answer 1

我太低排置评，但 请发表您的路线文件，但我认为有可能是一个问题在这里/articles/:article_id/comments

您在编辑说明没有一个ID。这是一个新的变量吗？请在该方向

Answer 2

1. 尝试评论编辑链接调查和检查它是否工作.. 是否行得通，那么问题是在编辑注释方法。

2. 你的路径应该是edit_article_comment_path（article_id的，COMMENT_ID），因为评论是嵌套控制器，它总是需要一个文章编号，以示对你的回应
