Rails應用程序投擲錯誤

Question

因此，我遵循本指南（http://richonrails.com/articles/basic-ajax-in-ruby-on-rails）在我的Rails應用程序中嘗試了一些基本的ajax，並在執行'rails s'命令時突然遇到了此錯誤。

$ rails s 
=> Booting WEBrick 
=> Rails 4.0.0 application starting in development on http://0.0.0.0:3000 
=> Run `rails server -h` for more startup options 
=> Ctrl-C to shutdown server

這是由什麼引起的？我所做的一切，因爲它sayd有..

Answer 1

它在你的routes.rb中的第一行，它應該是：

<Your app's name>::Application.routes.draw do

在你的情況下，它似乎是：

Ajax::Application.routes.draw do
