Converting decimal primary key to integer (oracle)

I am working with a legacy oracle database. The
primary key is not defined as an integer but as a number.
This results in a url with an id as a number, such as 1234.0 instead
of 1234. It works fine, but I would prefer 1234 to be displayed in
the url. I have attempted to redefine the model id method to
convert to an integer using to_i method, but no luck. Any ideas?

Thanks,
