If I want to change the default controller template created by scaffold in Rails it's dead easy - after Googling around I found I can just put a controller.rb file in lib/templates/rails/controller for the generator to pick up on instead of the default.
I cannot find any explanation of where I can do the same for a model file. I don't want to build a separate generator, I just want:
> rails generate model foo
to create foo.rb model file based on a model.rb template I make.
