Ruby 1.9.2 and Ramaze

OK, I just found out something interesting about ruby 1.9.2. They've changed the default LOAD_PATH to not include "." (current directory). What's this actually mean? Well, for starters just about every example that I and most others have written will no longer work. Here's an example with something from the current Ramaze prototype (generated when you do a ramaze create foo

require 'model/user'

this will generate errors if you run it with ruby 1.9.2. What you'll need to do instead is either



require_relative 'user'

The first version is compatible between 1.9 and 1.8 and the 2nd is 1.9 only. Both examples assume that the file this code is in is already in the model directory.

I should also note that Lee Jarvis has fixed the problem with the prototype already and it should be in the next update of Ramaze.

Like I said, most of my examples from previous posts are now wrong, but they should be pretty easy to fix once you know how. If you have any problems, be sure to let me know and I'll try to help get them worked out with you.

  1. Great heads up, never had the problem myself but that was because I generally use absolute paths for loadings files (e.g. http://pastie.org/1335405).
