ruby 类中的属性有可能是 public 的吗？假如向上面那个例子，有没有可能这么写 a.@side?

原来是真么回事，谢谢

@dddd1919 一个 request 在 cramp 里面有四个状态。你看看下面这段代码：我在 on_start 上注册了一个方法 set1，想让它输出点内容，但是不行。我不明白，start 方法是默认的，其中的内容能输出，但我自己添加的方法，却没法输出。你知道我哪错了吗？

class HomeAction < Cramp::Action on_start :set1 def set1 render "hello first" end

def start render "Hello World!" # Do more stuff render "Hello World Again!" end end

@dddd1919 请问你了解 cramp 吗？能否再问你个问题

有个 routes.rb 文件是这样的内容：

Check out https://github.com/joshbuddy/http_router for more information on HttpRouter

HttpRouter.new do add('/').to(HomeAction) end 是不是这个定义了 localhost:3000 要转到 HomeAction 去执行？

谢谢各位的解释，明白了

@yakczh udp 是什么？

@dddd1919 太谢谢你的介绍了。EventMachine 实际上就是 Ruby 的一个 gem，是吧

@dddd1919 再请教一下，那是不是需要先了解了 EventMachine 后，再来开始学习 Cramp？是这个顺序吗？

static_pages.css.scss 内容如下： // Place all the styles related to the StaticPages controller here. // They will automatically be included in application.css. // You can use Sass (SCSS) here: http://sass-lang.com/ @import "bootstrap";

config/environments/development.rb 内容如下：

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations.
  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = true

  # Adds additional error checking when serving assets at runtime.
  # Checks for improperly declared sprockets dependencies.
  # Raises helpful error messages.
  config.assets.raise_runtime_errors = true

  # Raises error for missing translations
  # config.action_view.raise_on_missing_translations = true
end

我找到一个帖子，说是把这两行内容换成如下两行就可以了，我试了一下，确实可以： <%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %> <%= javascript_include_tag "application", "data-turbolinks-track" => true %> 换成 <%= stylesheet_link_tag "default", media: "all", "data-turbolinks-track" => true %> <%= javascript_include_tag "default", "data-turbolinks-track" => true %>

但我 css 和 js 文件夹中明明都是 application 啊？并没有 default 文件，请问这是怎么回事？

系统的环境变量已经加了正确的路径，如下 C:\RailsInstaller\Git\cmd;C:\RailsInstaller\Ruby1.9.3\bin;C:\Program Files\Java\jdk1.8.0\bin;C:\ROR\mysql-5.1.50-win32\bin

请问在 rubymine 中哪里配置环境变量？

以下是 debugtest.rb 的内容 i=1 j=0 until i>1000000 i*=2 j+=1 end puts "i=#{i},j=#{j}"
