早上好，

我遇到了嵌套评论的问题。我有一个显示这些的部分，但我想在 .each 的底部添加一个删除片段。

以下是部分内容：

_snippets.html.erb

<% @snippets.each do |snippet| %>


                <%= raw(snippet.content)  %>

                <% if can? :manage, snippet %>
                <%= link_to 'delete', book_snippet_path(snippet), :method => :delete %>
              <% end %>



<% end %>

这是我的路线：

     book_snippets POST     /books/:book_id/snippets(.:format)          snippets#create
   edit_book_snippet GET      /books/:book_id/snippets/:id/edit(.:format) snippets#edit
        book_snippet PATCH    /books/:book_id/snippets/:id(.:format)      snippets#update
                     PUT      /books/:book_id/snippets/:id(.:format)      snippets#update
                     DELETE   /books/:book_id/snippets/:id(.:format)      snippets#destroy

这是堆栈错误，显示没有路由匹配更新？

No route matches {:action=>"update", :controller=>"snippets", :id=>nil, :book_id=>#<Snippet id: 4, content: "<p>YACHT!</p>\r\n", book_id: 4, created_at: "2013-11-15 09:12:20", updated_at: "2013-11-15 09:12:25", approved: true, user_id: 1>, :format=>nil} missing required keys: [:id]

我知道这可能是我错过的一些愚蠢的事情，但真的很想得到一些帮助来解决这个问题。

谢谢 ：）

你失踪了book_id。你的路线说

DELETE   /books/:book_id/snippets/:id(.:format)

在路径中需要 book_id。所以需要在参数中传递@book 对象。

            <%= raw(snippet.content)  %>

            <% if can? :manage, snippet %>
            <%= link_to 'delete', book_snippet_path(@book, snippet), :method => :delete %>
          <% end %>
