【问题描述】：

大家好，我正在尝试根据我在使用 ajax 更改 collection_select 时执行的咨询请求来刷新此 div #my_id4。

在我看来，像这样使用 javascript 进行选择...

 =collection_select(:department, :id, Department.all, :id, :name, options={:prompt=>"Seleccione departamento"})

这是javascript代码

:javascript
  $(document).ready(function(){
  $('#department_id').change(function(){
    $.ajax({
      url:"movements/find_by_department",
      type: "GET",
      data: { valor: $('#department_id').val() }
    });
  });
  })

在我的路由器中我有这个...

resources :movements do
  get 'find_by_department'
end

在我的控制器中我有这个

  def find_by_department
    @ideas_department = Idea.find_by_department_id(params[:valor])

    respond_to do |format|
      format.js {render  :action => :department_chart}
    end
  end

在视图 department_chart.js.erb 我有这个。

$("#my_id4").html("改变！！！")

但是当我执行应用程序时，我得到了这个..

Request URL:http://localhost:3000/movements/find_by_department?valor=5
Request Method:GET
Status Code:302 Found
Request Headersview source

并且响应为空！就像不执行该方法。

任何想法！！！

日志是这样的

【问题讨论】：

您能否包含此请求的 Rails 日志？

【解决方案1】：

在日志中：

Se ha consultado permiso para admin::movements::show
Redirected to http://localhost:3000/movements
Filter chain halted as :permission_check rendered or redirected

发出导致重定向的请求的用户似乎权限失败。
