…and the value of @expert_pagination is what? Have you debugged it to
see?
I assume you expect it to be an object of some sort with a method
“.current”; but the error is telling you that it’s a Fixnum…

yes the @expert_pagination is object

No it is not an object, it is a number. Have a look at the Rails
Guide on Debugging to get ideas on how to work out what is going on.

yes it is number ,but when the number is like 6,7 it is giving an error
‘‘undefined method ‘current’ for 852:Fixnum’’

I don’t understand what you are saying, you accept that
@expert_pagination is a number, but then expect to be able to say
@expert_pagination.current. A number does not have a method current
so the error is shown. What do you expect @expert_pagination.current
to do if @expert_pagination is a simple number?

I also don’t understand what you mean by “when the number is like 6,7”
6,7 is not a number, or do you mean 6.7?

Have you followed my earlier suggestion to read the Rails Guide on
debugging in order to find out what is going on? Please answer this
question if you reply, do not just ignore it.

Yes, the error is (as has been said several times already) that
something you think should be an object with the method .current, is
actually a number “6”… look at where you populate @book_pages.

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.
