带有 collection_select 的 rails 中的 ajax [英] ajax in rails with collection_select

问题描述

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

H everyone I am try to refresh this div #my_id4 with the request of the consult that I execute when change a collection_select with ajax.

我认为像这样的 javascript 选择...

I have in my view the select with javascript like this...

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

这是javascript代码

this is the javascript code

: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...

in my router I have this...

resources :movements do
  get 'find_by_department'
end

在我的控制器中我有这个

and in my controller I have this

  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department_chart.js.erb 视图中我有这个.

in the view department_chart.js.erb I have this.

$("#my_id4").html("change!!!")

$("#my_id4").html("change!!!")

但是当我执行应用程序时，我得到了这个..

but when I execute the application I obtain this..

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

响应为空！就像不执行方法一样.

and the responce in empty! is like don't execute the method.

任何想法！！！

日志是这样的

推荐答案

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

发出请求的用户似乎权限失败，导致重定向.

There looks to be a permission failure for the user making the request that is causing the redirection.
