Get Your Rails Metal in Order

I’ve been playing with Rails Metal for quite some time now. Under certain circumstances, one Metal would catch something I intended for another metal deeper in the middleware stack. Reordering became the order of the day. The only problem was that the Rails Guide was in the works and I didn’t want to hack my metal files to put them in alphabetical order to match the order I wanted them in.

So, without further ado, here is how you reorder your Rails Metal middleware stack:

Open you environment.rb file:

vi config/environment.rb

Then add this line inside the initialization block:

config.metals = ["FirstMetal", "ThirdMetal", "SecondMetal", "FinalMetal"]

The strings in the array are the names of the metal files in camel case.
