Problem with Kaminari pagination on Rails Active Record joins

	Error Type : 1. Use "includes" instead of "joins" with kaminari pagination.

	example :
	books = Book.joins( :other_category ).where(['books.published_on is not null and other_categories.name like ?', "%#{category_name}%"]).order('books.title').page( page ).per( per )


	it makes sql for counting the record as :
	SELECT COUNT(*) FROM `books` WHERE ( books.id IN (SELECT DISTINCT other_categories.book_id FROM other_categories WHERE other_categories.name LIKE '%Fiction%')) LIMIT 10 OFFSET 20

	This sql failed to return the count dues to limit and offset.
