     <div class="panel-body">

      <%= @article.body %> 
      <div class="comments">

     <div class="panel-body">

     </div> 
    </div> 

_comment.html.erb：routes.rbを

<div class="comment clearfix">

    devise_for :users 
    resources :articles do 
    resources :comments 
    end 
    root 'articles#index' 
end 

経路：

 article_comments GET /articles/:article_id/comments(.:format)   comments#index 
         POST /articles/:article_id/comments(.:format)   comments#create 
    new_article_comment GET /articles/:article_id/comments/new(.:format)  comments#new

     article_comment GET /articles/:article_id/comments/:id(.:format)  comments#show 
         PATCH /articles/:article_id/comments/:id(.:format)  comments#update 
         PUT /articles/:article_id/comments/:id(.:format)  comments#update 
         DELETE /articles/:article_id/comments/:id(.:format)  comments#destroy 

ショー：/物品/ 7％2F /コメント/ 7

<%= link_to "destroy", [@article, comment], method: :delete, data: { confirm: "Are you sure?" } %> 

ショー：HREF = "/物品/ 7 /コメント/ 3いくつかは、どこが間違っdestroy routes」

？

Answer 1

あり二つの問題：<%= link_to "destroy", article_comment_path(@article, @comment), method: :delete, data: { confirm: "Are you sure?" } %>あなたは '[]' ブラケットを使用していた。

2. 、私はあなたのフィードバックを知ってみましょうparams[:id]

でparams[:comment_id]を変更！ ありがとう
