Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling @article.media

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.

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

// Change font (ctrl a)
var doc = context.document,
    selection = context.selection,
    font_name = [doc askForUserInput:"Font name:" initialValue:"Arial"];

function check_layer(layer){
  log(layer)
  var className = layer.className()
  log("Checking layer " + layer + " of klass: " + className)
  if (className == "MSTextLayer") {

This guide shows how to set up a PHP and MySQL development environment using OSX's built-in Apache, using Homebrew to install necessary components. With this strategy, you can use different versions of PHP for certain virtual hosts.

VirtualHostX is a convenient way to manage development sites, but not required.

Install PHP and MySQL with Homebrew

brew update
brew install php56
brew install php56-mcrypt
brew install mysql
