# controller
if @item.publish
  flash[:notice] = "xxxx"
end
# modle
class Item < ActiveRecord::Base

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

This list has been superseded by Public APIs. Check there for APIs with Auth: No, HTTPS and CORS Yes.

List of data APIs that require no server-side auth or private credentials, and are thus good for small browser-only JS projects.

1. the default index.html does not work well in prodution mode, so do not borther to config that, just delete it and go on.

2. To put things in production mode, do

    rails g scaffold items name:string
    rake db:migrate RAILS_ENV=production
    rm public/index.html
    #change route.rb point root to items#index
    rake assets:precompile
    sudo service nginx restart
   

./config/unicorn_init.sh stop

#Behold, the nav_link:

The nav_link helper works just like the standard Rails link_to helper, but adds a 'selected' class to your link (or its wrapper) if certain criteria are met. By default, if the link's destination url is the same url as the url of the current page, a default class of 'selected' is added to the link.

For full usage details, see: http://viget.com/extend/rails-selected-nav-link-helper

Drop nav_link_helper.rb into app/helpers in your Rails 3.x app and enjoy.
