Chrome控制台和rails日志中的输出不同

Question

我正在尝试通过跨平台表单在rails中添加数据。数据也在添加，但我的浏览器中的响应始终是一些json对象的错误。

rails log中的输出： -

   (8.7ms)  COMMIT
Entered to true part
Completed 200 OK in 104ms (Views: 0.2ms | ActiveRecord: 36.8ms)

但在浏览器中显示如下： -

Object {readyState: 0, responseJSON: undefined, status: 0, statusText: "error"}
test.html?_ijt=m511tgfk5o03pohpjpk2ebuppf:88 
Navigated to http://localhost:63342/zeftware/shitalluitel.github.io/test.html?batch%5Bstatus%5D=0

提交表格的代码是： -

$(document).ready(function () {
        $('#submit-button').click(function() {
            $.ajax({
                type: "POST",
                url: "http://localhost:3000/batches.json",
                beforeSend: function(xhr) {xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'))},
                xhrFields: {
                    withCredentials: true
                },
                dataType: "json",
                data: {     
                    batch: {
                      name: $("#name").val(),
                      course_id: $("#course_id").val(),
                      start_date: $("#start_date").val(),
                      end_date: $("#end_date").val(),
                      batch_status: $("#batch_status").val(),
                      }
                },
                error: function(error){
                    console.log(error);
                },
              success: function(data) {
                         console.log(data);
                         return false;
                      },
            })
        });
    })

我的控制器代码是： -

class BatchesController < ApplicationController
  skip_before_action :verify_authenticity_token
  def new
    @batch = Batch.new
    respond_to do |format|
      format.json
      format.html
    end
  end

  def create
    @batch = Batch.new(batch_param)
    respond_to do |format|
       if @batch.save
         puts "Entered to true part #{@batch.name}"
         format.html { redirect_to @batch, notice: "Save process completed!" }
         format.json { render json: @batch}
       else
         puts "entered to false part"
          format.html {
            flash.now[:notice]="Save proccess coudn't be completed!"
            render :new_batch
          }
          format.json { render json: @batch.errors}
      end
    end
  end
end
