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