在rails中对控制器动作进行ajax调用

Question

I am trying to make an ajax call to my controller

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

In my javascript file i have

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

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

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

Answer 1

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

post 'patient_record/export'

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)

Answer 2

You also need a route for the export action in your config/routes.rb file, something like

resources :patient_records do
  member do
    post :export
  end
end

You can check to see if this already exists by running rake routes | grep 'export' rake routes | grep 'export' .
