Rails 3 - Ajax Put request gives 404, yet it works

I am updating a task status from my deal overview page where i am displaying my list of tasks for that deal

It works, the task gets updated. However, i get a nasty 404 error.

Any ideas?

js/coffeescript

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"

I'm open to suggestions if this is not the "right way" to do it. Though the requirement is that it must be done with ajax.

Thanks in advance!

You need to add the account to your redirect, e.g.

# 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], ...) }

Also, as noted in the comments, your Ajax request isn't asking for javascript, but rather HTML. You'd need to do what Kristian PD says and put dataType: script to the options to specify JS, e.g.

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

Try

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

I don't think it's rendering your JS response and it's trying to use the HTML redirect (which also has problems as noted by numbers)
