I have a generator that creates a model amongst other files. We need  
to be able to interpolate data into that file but nothing is actually  
being interpolated. It is simply copying the file verbatim.

I was wondering if you could enlighten me as to what I am doing wrong.

Here is the generator and the model.rb file:

Thanks a lot!
