The first question to ask yourself is, "Why is it important to use dependency injection in this specific scenario?" After all this is Ruby, not some lame statically typed language like Java or something. In Java Dependency Injection (DI) is uses to solve a lots of issues that are mostly due to limitations of the language itself. In fact it requires looking outside of the language itself to even support DI (i.e. XML configuration files or Java annotations). There's a tendency to make DI sound like something magical or complicated in the Java world, but in Ruby (and other dynamically typed languages) you won't here much about it. Mostly because it's a really simple concept with a really simple implementation. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
