Question

my routes.rb

root 'pages#home'
get 'about', to: 'pages#about'
resources :articles
match ':controller(/:action(/:id))', :via => [:get, :post]

my articles_controller.rb

def delete
   @article = Article.find(params[:id])
end

def destroy
  article = Article.find(params[:id])
  article.destroy
  flash[:notice] = "Article destroyed successfully."
  redirect_to(:action => 'index')
end

我的delete.html.rb

<h2>Delete Article</h2>

<div class="subjects delete">
<h2>Delete Subject</h2>

<%= form_for(:article, :url => {:action => 'destroy', :id => @article.id}) do |f| %>
<p>Are you sure you want to permanently delete this subject?</p>
<p><%= @article.title %></p>

  <div class="form-buttons">
    <%= submit_tag("Delete Article") %>
  </div>
<% end %>
</div>

现在问题是当我点击编辑文章重定向到 http://localhost:3000/articles/7/edit

显示重定向到localhost:3000/articles/7

删除重定向到localhost:3000/articles/delete/8的位置当点击删除按钮时，它显示The action '8' could not be found for ArticlesController

为什么我不会被重定向到localhost:3000/articles/8/delete

我将routes.rb更改为

match ':controller(/:id(/:action))', :via => [:get, :post]

在此删除中有效但编辑不是。

您最好使用路由的resources指令：

#config/routes.rb
resources :articles #-> url.com/articles/:id/destroy
resources :pages, only: [], path: "" do
   get :about, on: :collection #-> url.com/about
end
root 'pages#home'

以上将提供正确的路线。

您的问题是您提交表单以尝试更改该值。这不起作用;你需要：

#app/views/articles/show.html.erb
<%= button_to "Delete", article, method: :delete, data: { confirm: "Are you sure?" } %>

这将调用您的posts#destroy控制器＆amp;解雇你的代码（看起来没问题）。
