Rails - Using Kaminari for pagination?

I'm trying to get the next page link. How would I do this? I get the following error when calling link_to_next_page

undefined method `link_to_next_page'

query = Posts.page(1).per(5).includes(author: :profile)

link = link_to_next_page(query, 'Next-Page')

def paginate(query)
   query.offset!((@page-1) * @per_page)
   query.limit!(@per_page+1)

   result = query.to_a

   if (result.size > @per_page)
     result.pop
     response.headers['Link'] = CREATE_NEXT_AGE_LINK_HERE
   end

   result
end

Link helpers are not accessible into controllers. You can include entire helper module into your controller, but better use view_context to access particular helper method: 

query = Posts.page(1).per(5).includes(author: :profile)    
link = view_context.link_to_next_page(query, 'Next-Page')

Good luck!
