How to use will paginate with array of hashes

Suppose we have an object  which is having value as array of hashes (In example @student['results'] is an array of hashes which is returned from some API call)

so the is given below

  @students = WillPaginate::Collection.create(@page, @page_size) do |pager|
        # inject the result array into the paginated collection:
        pager.replace(@student['results'])
        unless pager.total_entries
          # the pager didn't manage to guess the total count, do it manually
          pager.total_entries = (@student['total_pages'] * @page_size)
        end
      end
