Question

我正在从交易概览页面更新任务状态，我在该页面中显示该交易的任务列表

它有效，任务得到更新。但是，我得到了一个令人讨厌的404错误。

有什么想法吗？

JS / CoffeeScript的

jQuery ->
    $(".complete_task").live "click", ->
    task_id = $(this).attr("value")
    alert "checkbox clicked" + task_id
    $('ul#tasks').sortable "refresh"
    $.ajax 
      url: "tasks/" + task_id
      data: "&task[is_completed]=2"
      type: "PUT"
      success: ->
        $(this).addClass "done"

我的firebug输出

如果这不是“正确的方法”，我愿意接受建议。虽然要求是必须用ajax完成。

提前致谢！

Answer 1

您需要将帐户添加到重定向，例如

# adding it as @account, change to however you're referencing it.
# params[:account_id] should also work.
format.html { redirect_to([@account, @task.deal, @task], ...) }

此外，正如评论中所述，您的Ajax请求不是要求javascript，而是要求HTML。你需要做Kristian PD所说的并将dataType: script放到指定JS的选项中，例如。

$.ajax 
  url: "tasks/" + task_id
  data: "&task[is_completed]=2"
  type: "PUT"
  dataType: "script"
  success: ->
    $(this).addClass "done"

Answer 2

尝试

 $.ajax 
      url: "tasks/" + task_id
      dataType: "script"
      data: "&task[is_completed]=2"
      type: "PUT"
      success: ->
        $(this).addClass "done"

我认为它不会呈现您的JS响应，并且它正在尝试使用HTML重定向（也存在数字所指出的问题）

Rails 3 - Ajax Put请求给出404，但它可以工作
