Ruby on rails ActionController:：RoutingError没有与之匹配的路由[DELETE]

我正在写一个显示新闻提要的页面，在删除帖子时遇到了问题。当我试图删除某个帖子时，它会给我一个错误：

ActionController:：RoutingError（没有与[DELETE]匹配的路由“/news.305”）：

例如（305是id）

我做错了什么

这是我的新闻

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

以下是完整的错误代码：

这是路线

Rails.application.routes.draw do

  get 'password_resets/new'
  get 'password_resets/edit'

  root 'static_pages#home'
  get 'history' => 'static_pages#history'
  get 'help' => 'static_pages#help'
  get 'contact' => 'static_pages#contact'
  get 'about' => 'static_pages#about'
  get 'downloads' => 'static_pages#downloads'
  get "news" => 'news#news_page'
  get 'signup' => 'users#new'
  get 'testpage' => 'static_pages#testpage'
  get 'delete_inactive_users' => 'users#delete_inactive_users'

  get 'login' => 'sessions#new'
  post 'login' => 'sessions#create'
  delete 'logout' => 'sessions#destroy'

  resources :users
  resources :account_activations, only: [:edit]
  resources :password_resets, only: [:new, :create, :edit, :update]
  resources :news, only: [:create, :destroy]
end

以下是包含删除的部分：

<% 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 %>

尝试传入实际的新闻id:

<%= link_to 'Destroy',  { action: :destroy, id: news.id }, 
       method: :delete,
       data: { confirm: "Delete this news item?" } 
%>

好的！我发现了问题。显然，我不应该给我的模特取名为“新闻”。因为它链接到用户模型，用户可以有很多新闻。当我执行类似user.news的操作时，会产生名称冲突。我重新创建了一个名为“Newspost”的模型，所以现在user.Newspost不会混淆rails。现在我可以做删除没有任何问题

是否可以包括

routes.rb

文件和显示错误的视图？routes.rb和视图已添加。谢谢，我想知道。成功删除时是否应返回“已启动删除”//news/305”，而不是“已启动删除”//news.305”？@Evilmuffin yes。当然应该是

/news/305

问题是为什么不是？

<%= link_to 'Destroy',  { action: :destroy, id: news.id }, 
       method: :delete,
       data: { confirm: "Delete this news item?" } 
%>
