我正在编写一个页面，显示新闻源并且无法删除帖子。当我试图删除某个职位，它会给我一个错误：ActionController :: RoutingError没有路由匹配[DELETE]
的ActionController :: RoutingError（无路由匹配[删除]“/news.305”）：
例如（305作为ID ）
我在做什么错？
这里是我的news_controller
class NewsController < ApplicationController
before_action :logged_in_user, only: [:create, :destroy]
before_action :admin_user, only: [:create, :destroy]
def news_page
@news = News.paginate(page: params[:page], per_page: 10)
if logged_in?
@news_post = current_user.news.build if current_user.admin?
@news_feed = News.paginate(page: params[:page], per_page: 8)
end
end
def create
@news_post = current_user.news.build(news_params)
if @news_post.save
flash[:success] = "News updated!"
redirect_to news_url
else
@news_feed = []
render "news/news_page"
end
end
def destroy
News.find(params[:id]).destroy
flash[:success] = "News deleted"
redirect_to news_url
end
private
def news_params
params.require(:news).permit(:content, :news_title)
end
末
这里是路线：

这里是路线.rb
Rails.application.routes.draw do

resources :users

end
下面是一个包含删除谐音：
<% if @news_feed.any? %>
<ol class="news news_feed">
<% @news_feed.each do |news| %>
<li id="news-<%= news.id %>">
<aside class="col-md-2">
<span class="news_title"><%= news.news_title %></span>
</aside>
<span class="news_content"><%= news.content %></span>
<span class="user"><%= link_to news.user.name, news.user %></span>
<span class="timestamp">
Posted on <%= news.created_at.to_time.strftime('%m/%d/%Y') %>
<%= link_to "delete", news, method: :delete,
data: { confirm: "Delete this news item?" } %>
</span>
</li>
<% end %>
</ol>
<%= will_paginate %>
<% end %>
你可以包括你的'routes.rb'文件和视图给你的错误？ –
routes.rb和视图添加。谢谢。 – Evilmuffin
我在想。应该在成功删除时返回“开始删除”/ news/305“'而不是'开始删除”/news.305“'？ – Evilmuffin
