ActionController::RoutingError 没有路线匹配 [DELETE]

ActionController::RoutingError No route matches [DELETE]

我正在编写一个显示新闻提要的页面,但在删除 post 时遇到了问题。当我试图删除某个post时,它会给我一个错误:

ActionController::RoutingError(没有路由匹配 [DELETE] "/news.305"):

例如(305为id)

我做错了什么?

这是我的 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

结束

这里是route.rb

Rails.application.routes.draw do

  get 'login' => 'sessions#new'
  post 'login' => 'sessions#create'

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

这是包含删除的部分:

<% 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,我不应该命名我的模型 'News'。因为它链接到用户模型和用户可以 has_many 新闻。当我做类似 user.news 的事情时,它造成了名称冲突。我重新创建了一个名为 "Newspost" 的模型,所以现在 user.news 帖子不会混淆 rails。现在我可以毫无问题地删除了。
