Creating variable.

Good morning,

I am beginning to develop a ruby part of a web. I
I have the driver code "book" and I spend their ID in the variable
Book.current_book.id, but gives me the following error.

undefined method `current_book' for Book:Class

How do I define the variable to my tests?

Thank you

You'll have to show us exactly what it is you are doing/trying to do.
