我按照#302 In-Place Editing 截屏教程来实现 best_in_place。

视图位于visitors

到目前为止，编辑工作正常。但是，在我按 Enter 后它无法保留更改，并且出现 javascript 错误：

POST http://localhost:3000/visitors 404 (Not Found)

在我的访问者/new.html.erb 中，我实现了：

<%= best_in_place @visitor, :special %>

在我的 visitor_controller.rb 中，我实现了：

class VisitorsController < ApplicationController

  respond_to :html, :json

  def show
    @visitor = Visitor.find(params[:id])
  end

  def new
    @visitor = Visitor.new
  end

  def create
    @visitor = Visitor.new(secure_params)
    if @visitor.valid?
      @visitor.update_spreadsheet
      flash[:notice] = "Chose #{@visitor.favorite}."
      render :new
    else
      render :new
    end
  end


  def update
    @visitor = Visitor.find(params[:id])
    @visitor.update_attributes(secure_params)
    respond_with @visitor
  end

  private

  def secure_params
    params.require(:visitor).permit(:favorite, :comment)
  end
end

在我的 application.js 中，我有：

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap
//= require_tree ./bootstrap
//= require_tree ./styler
//= require social-media
//= require users
//= require jquery.purr
//= require best_in_place

$(document).ready(function() {
    $('.best_in_place').best_in_place();
});

知道如何解决这个问题吗？如果我需要提供更多信息，请告诉我。
