轨道上的红宝石 - 操作控制器：：路由错误：使用复选框 + ajax 时没有路由匹配 ->

Question

我正在构建一个简单的任务管理应用程序，当我试图处理复选框以指示任务完成时，会发生奇怪的问题。

下面是我想出来的代码:

<%= check_box_tag "id", "id", task.done, 
    :onclick => remote_function(
      :update => "task", 
      :url => { :action => :update, :controller => :tasks, :id => task.id }, 
      :with => "'task[done]=true'", 
      :complete => "alert('hi')"  ) %>

它会打印复选框，并且会根据task.done的状态自动检查。但是当我触发onclick并查看日志时，我看到以下条目:

开始POST "/tasks/20" for 127.0.0.1 at 2011-04-25 23:15:44 -0300ActionController::RoutingError (No route matches "/tasks/20"):

查看我的配置/路由。我有:

 resources :tasks

你能帮我找出我做错了什么吗?为什么没有找到路线?

下面是_task.html的完整代码。erb 视图。

<tr>
  <td class="task">
    <span class="tasktitle">

<%= check_box_tag "id", "id", task.done, 
    :onclick => remote_function(
      :update => "task", 
      :url => { :action => :update, :controller => :tasks, :id => task.id }, 
      :with => "task[done]=true", 
      :complete => "alert('hi')"  ) %>

<span class="<%= if (task.done) then "editable_field_complete" else "editable_field" end %>" id="task_title_<%= task.id %>">
<%= best_in_place task, :title, :type => :input %>
</span>
</span>
    <span class="taskdelete"><%= link_to "delete", task, :method => :delete, :class => "delete",
                                     :confirm => "You sure?",
                                     :title => task.title %></span>
    <span class="taskcreated">
      Created <%= time_ago_in_words(task.created_at) %> ago.
    </span>
  </td>
</tr>

谢谢大家

问题似乎是remote_function提交的数据与POST协议，但当你在路由中使用资源。那么在调用更新操作时，它只接受PUT协议。

尝试在remote_function中添加以下参数:

:method=>:put

那么最终结果将是:

<%= check_box_tag "id", "id", task.done, 
    :onclick => remote_function(
    :update => "task", 
    :url => { :action => :update, :controller => :tasks, :id => task.id }, 
    :method => :put,
    :with => "task[done]=true", 
    :complete => "alert('hi')"  ) %>
