ruby on rails - Filtered Pagination with Kaminari -

i set website uses ajax-pagination powered kaminari. have set simple filtering , searching, can browse list on http://example.com/products/filter?query=blah.

i'm using kaminari's built-in link_to_next_page helper generate next-page link. problem comes because generated link ignores queries/filters, sending on http://example.com/products/filter?query=blah http://example.com/products?page=2

one solution i've toyed rewrite link_to_next_page helper include filters , search-terms, (as things) more work expected. there better way?

according link_to_next_page document, should query_string env, keep query parameter

def link_to_next_page(scope, name, options = {})   params = options.delete(:params) ||(rack::utils.parse_query(env['query_string']).symbolize_keys rescue {}) 

if not work expect, can pass params yourself

<%= link_to_next_page @items, 'next page', :params => params %>
