在共享主机上部署 ruby​​ on rails - 路由问题

Question

我是 Rails 新手。我正在努力让一个简单的 helloworld rails 应用程序（无数据库）在共享主机上工作。

开发日志

Processing ApplicationController#index (for 122.61.170.222 at 2012-12-17 17:46:09) [GET]

ActionController::RoutingError (No route matches "/Say/hello" with {:method=>:get}):


Rendering rescues/layout (not_found)

我的 Rails 设置：http://scifiwear.com/rails_setup.png

rails setup http://scifiwear.com/rails_setup.png

我的子域设置：http://scifiwear.com/subdomain.png

subdomain setup http://scifiwear.com/subdomain.png

服务器版本：

Ruby 版本：1.8.7 宝石版本：1.8.16 Rails 是 2.3.14

我配置 helloWorld 应用程序的步骤：

1. 使用网络表单http://scifiwear.com/rails_setup.png创建的应用程序

2. cd myapp14

3. ruby 脚本/生成控制器说再见

4. http://myapp14.scifiwear.com/快乐！

5 http://myapp14.scifiwear.com/say/hello 不开心！

我的 routes.rb 的最后 4 行：（未改动）

# consider removing or commenting them out if you're using named routes and resources.

map.connect ':controller/:action/:id'

map.connect ':controller/:action/:id.:format'

end

任何建议都非常感谢。

尝试上一个问题的答案：Problems running Ruby on Rails apps on shared hosted server;在这种情况下，它们可能会有所帮助。

我尝试使用rails 2.3.14 和ruby 1.8.7-p371 在本地重现相同的错误；没有收到错误信息。路由文件与您拥有的类似。

日志跟踪如下：

Processing SayController#hello (for 127.0.0.1 at 2012-12-20 15:52:23) [GET]
Rendering say/hello
Completed in 35ms (View: 34, DB: 0) | 200 OK [http://localhost/say/hello]

鉴于此托管服务器上的 ruby​​ 和 rails 版本非常旧，您可能很难就安装时遇到的问题获得帮助。而且您在学习这些概念时也会遇到困难。

我的建议是让您改用最新版本的 ruby​​ 和 rails（并了解使用 rails 进行 Web 开发的最佳实践），遵循 Michael Hartl 的优秀且免费提供的在线书籍：Ruby on Rails Tutorial
