Question

我有问题使用link_to_remote

link_to_remote "Delete this post", :update => "posts", :url => { :action => "destroy", :id => post.id }

此代码在html代码下面生成

<a href="#" onclick="new Ajax.Updater('posts', '/blog/destroy/3', {asynchronous:true, evalScripts:true}); return false;">Delete this post</a>

但我的应用没有。我的HTML是

<a href="#" onclick="new Ajax.Updater('posts', '/blog/6', {asynchronous:true, evalScripts:true, parameters:'authenticity_token=' + encodeURIComponent('2C4Yo8OIDN+dm9oieL37uRg++PuWa8LCz18gW5Cu+Vg=')}); return false;">Delete this post</a>

url在哪里销毁？

我预计'/ blog / destroy / 6'但实际上是'blog / 6'

问题是什么？

我的rails版本是2.3.5

追加问题

确实是我在更新操作中遇到的问题

我想使用下面的代码

link_to_remote "toggle", :url => { :action => "update", :id => post.id }

但是这段代码不是'博客/更新/ 6'，它也是'博客/ 6'......

如果点击链接发出此错误

ActionController::UnknownAction (No action responded to 6. Actions: create, index, new, show, and update):

....我的route.rb是默认的

ActionController::Routing::Routes.draw do |map|
  map.resources :aaa

  map.resources :timetables
  map.resources :alarams
  map.resources :users

  map.login 'login', :controller => 'user_sessions', :action => 'new'  
  map.logout 'logout', :controller => 'user_sessions', :action => 'destroy'  
  map.resources :user_sessions  

  # The priority is based upon order of creation: first created -> highest priority.

  # Sample of regular route:
  #   map.connect 'products/:id', :controller => 'catalog', :action => 'view'
  # Keep in mind you can assign values other than :controller and :action

  # Sample of named route:
  #   map.purchase 'products/:id/purchase', :controller => 'catalog', :action => 'purchase'
  # This route can be invoked with purchase_url(:id => product.id)

  # Sample resource route (maps HTTP verbs to controller actions automatically):
  #   map.resources :products

  # Sample resource route with options:
  #   map.resources :products, :member => { :short => :get, :toggle => :post }, :collection => { :sold => :get }

  # Sample resource route with sub-resources:
  #   map.resources :products, :has_many => [ :comments, :sales ], :has_one => :seller

  # Sample resource route with more complex sub-resources
  #   map.resources :products do |products|
  #     products.resources :comments
  #     products.resources :sales, :collection => { :recent => :get }
  #   end

  # Sample resource route within a namespace:
  #   map.namespace :admin do |admin|
  #     # Directs /admin/products/* to Admin::ProductsController (app/controllers/admin/products_controller.rb)
  #     admin.resources :products
  #   end

  # You can have the root of your site routed with map.root -- just remember to delete public/index.html.
  map.root :controller => "welcome"

  # See how all your routes lay out with "rake routes"

  # Install the default routes as the lowest priority.
  # Note: These default routes make all actions in every controller accessible via GET requests. You should
  # consider removing or commenting them out if you're using named routes and resources.
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
end

Answer 1

您需要在链接参数中添加:method => 'delete'。您似乎已将posts声明为路由表中的资源。

Answer 2

我猜你使用的是nifty-scaffold生成器，它可以让你选择包含/排除destroy动作。如果那不是您正在使用的生成器，那么您没有在控制器中定义的“销毁”操作。因此错误：

ActionController :: UnknownAction（没有操作响应6.操作：创建，索引，新建，显示和更新）：

控制器中没有“销毁”动作来响应。

rails中的link_to_remote，问题传递：id
