Thoughts about Rails Presenters

This is a collection of links, examples and rants about Presenters/Decorators in Rails.

---

The "Decorator" pattern slowly started gaining popularity in Rails several years ago. It is not part of core Rails, and there's many different interpretations about how it should work in practice.

Jay Fields wrote about it in 2007 (before he switched back to Java and then Clojure): http://blog.jayfields.com/2007/03/rails-presenter-pattern.html

Most examples I found tell you to run rvmsudo or passenger-install-nginx-module. I ran into problems with these because:

1. rvmsudo leaves root owned directories and files under rvm passenger gem directory. This will give you seemingly odd errors later when you try to remove/upgrade passenger gem, or try to use homebrew to install passenger.

2. There's no good place to put nginx using passenger-install-nginx-module. Putting it under /usr/local means you have to remember it's there amongst homebrew files. Anywhere else, you still have to remember you put it there. We'd rather manage nginx install via homebrew.

So to install everything with homebrew, this is what it took:

gem install passenger
