要实现AJAX调用控制器在轨操作 [英] making an ajax call to controller action in rails

问题描述

我试图使一个Ajax调用我的控制器

I am trying to make an ajax call to my controller

class PatientRecordController < ApplicationController
  def export
     ....
  end
end

在我的JavaScript文件中，我有

In my javascript file i have

$(document).ready(function(){
    freezeTopRow($('#dataTable'));
    $("#export").click(function(){
        $.ajax({url: "patient_record/export", type: "POST"});
    });
});

当我检查元素和调试，当我点击我的页面导出标签。我打的功能但它从来没有得到到控制器

when i inspect element and debug and when i click the export tag on my page. i hit the function however it never gets to the controller

另外，我有2个控制器和2次。在我的其他控制器和视图我做同样的事情，它的工作原理

Also I have 2 controllers and 2 views. In my other controller and view I do the same thing and it works

推荐答案

你检查，你 routes.rb中碰到这样的：

Have you checked that you routes.rb have something like:

post 'patient_record/export'

也许Rails的不知道路线，以便阿贾克斯不工作（如果你能得到从浏览器的动作就意味着你只有一个 GET 集，你可以检查，改变在Ajax调用请求的类型）

Maybe Rails doesn't know the route so the ajax isn't working (if you can get to the action from your browser it means that you have only a GET set, you can check that changing the type of the request in the ajax call)
