The cause of the error is simple.
1. @book_pages is the number 6.
2. You have the code @book_pages.current
3. This is the same as saying 6.current
4. The number 6 does not have a method called current
5. Therefore there is the error that the method 'current' is not
defined for the number 6.

Now if your question is 'why is @book_pages the number 6' then you
must look at the code where you setup @book_pages.

I think you would be better to work through some tutorials first
however. I suggest that you forget what you are doing for a few days
and work right through something like railstutorial.org, which is free
to use online. Then you will have a better grasp of the fundamentals
of RoR and will be able to answer your own questions.
