#5 楼 @metal 确实是没有

bundle exec rake assets:precompile RAILS_ENV= production

的问题

虽然 openshift 的提示了

remote: Precompiling with 'bundle exec rake assets:precompile'

但是似乎它没有正确工作，当我在.openshift/action_hooks/deploy 的文件中增加

bundle exec rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets

重新上传，application.css 工作正常。

#4 楼 @metal

还没有试，刚好有这个想法。

在本地执行 rake assets:precompile 又可以正确生成哦，只是上传到 openshift 的时候没有生成，这是让人困惑的地方。

#1 楼 @metal 上传到 openshift 的时候，显示已经执行

remote: Precompiling with 'bundle exec rake assets:precompile'

而且同目录下的 home.scss 已经正确生成 home.css

不确定是否跟 production.rb 有关不，这里也贴一下

cat config/environments/production.rb

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

  # Code is not reloaded between requests
  config.cache_classes = true

  # config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)

  # Use a different cache store in production
  # config.cache_store = :mem_cache_store

  # Enable serving of images, stylesheets, and JavaScripts from an asset server
  # config.action_controller.asset_host = "http://assets.example.com"

  # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)

招远程办公的不？

#19 楼 @chenge 同意！

#10 楼 @neverlandxy_naix 第一次打开页面，得到的 object_id 是 33495240 第二次刷新页面，得到的 object_id 是 35038600

呵呵，有啥优化方法？

#9 楼 @chenge 有没有具体点的？

我使用了 helper 方法来实现本帖提到的这些需求

def site_conf(key)
  @conf ||= YAML.load_file("#{Rails.root}/config/site.yml")
  @conf[key]
end

这样，我在页面 HAML 模板中就可以这样使用了

%h1= link_to site_conf('title'), root_url

我的 YAML 文件 site.yml

title: i'm a ruby bird

现在基本能工作了，单还是有一个问题，就是 每次调用 site_conf，是不是就直接返回@conf了？ 我知道

@conf ||= YAML.load_file("#{Rails.root}/config/site.yml")

是有定义就返回@conf,没有就执行后一句

但是 ruby 的变量有作用域，第一调用 site_conf 获得的@conf,再第二次调用是否依然可用？？

#1 楼 @iBachue 好主意

#4 楼 @sevk 这个方法看起来比较优雅

#2 楼 @deathdealer 是的，参照了这个：http://stackoverflow.com/questions/5370164/disabling-devise-registration-for-production-environment-only

问题已经解决，谢谢各位。就是在 model 中删除可注册选项即可。

参考这个：http://stackoverflow.com/questions/9480741/what-variable-should-i-place-in-this-form-to-edit-a-comment-rails

把 app/views/comments/_form.html.haml 改为

= form_for([@post, @comments]) do |f| 
  .field
    = f.label :commenter
    %br/
    = f.text_field :commenter
  .field
    = f.label :body 
    %br/
    = f.text_area :body
  .actions
    = f.submit 

然后在 app/controllers/posts_controller.rb 的 show 中添加

@comments = @post.comments.build

在 app/controllers/comments_controller.rb 的 edit 中修改如下

def edit
  @post = Post.find(params[:post_id])
  @comments = @post.comments.find(params[:id])
end

现在可以编辑了，感谢大家

刚刚看到了删除的功能，但是在 post 下编辑 conmment，还是没有发现
