Does dependency injection exist in Rails?
dependency-injection, ruby, ruby-on-rails, spring
Solution
Dependency injection is usually unnecessary with Ruby. Jamis Buck blogged extensively about the reasons why. Well worth a read.
Problem
Does the fact that Rails have an MVC approach mean that is has dependency injection? Or is there a reason that we don't talk about dependency injection in Rails? If Rails does have dependency injection, what does it consist of?
