Ruby on rails Rails在使用ajax表单时突然出现错误

我制作了一个按钮，单击该按钮可创建一个

shopping\u cart\u项目

，然后重定向到显示删除该

shopping\u cart\u项目的按钮的同一页面。这辆车很好用。当我尝试使用ajax时，“从购物车中删除”按钮工作正常，但当我单击“添加到购物车”按钮时，突然出现以下错误：

列表控制器：

 listtype_regexp = Regexp.new([:shopping_cart_items, :currently_taking_items, :recently_viewed_items].join("|"))
 resources :lists, only: [:create, :destroy], path: ':listtype', constraints: { listtype: listtype_regexp }

class ListsController < ApplicationController


  def create
    addToList!(params[:course_id], current_user.shopping_cart_items)
    respond_to do |format|
      format.html { redirect_to controller: 'browse_courses', action: 'show', type: 'courses', id: params[:course_id] }
      format.js
    end
  end

  def destroy
    removeFromList!(params[:course_id], current_user.shopping_cart_items)
    respond_to do |format|
      format.html { redirect_to controller: 'browse_courses', action: 'show', type: 'courses', id: params[:course_id] }
      format.js
    end
  end
end

我的假设正确吗？您描述为“用于向购物车添加项目的表单”的文件是browse\u courses/cart？此外：内部服务器错误是“/shopping\u cart\u items”post请求的一部分吗？你有没有试过“耙路”来看看到底有什么路？是的，这是正确的！我不知道你说的是什么意思：“内部服务器错误是“/shopping\u cart\u items”上post请求的一部分吗？我确实运行了“rake routes”查看上面的编辑我只是想了解问题：）在将ajax添加到应用程序并单击“添加到购物车”按钮时，会出现错误，对吗？您也可以在没有AJAX控件的情况下发布页面吗？：）
