module Kaminari::Helpers::SinatraHelpers::HelperMethods
Public Instance Methods
A simple “Twitter like” pagination link that creates a link to the next page. Works on Sinatra.
Examples¶ ↑
Basic usage:
<%= link_to_next_page @items, 'Next Page' %>
Ajax:
<%= link_to_next_page @items, 'Next Page', :remote => true %>
By default, it renders nothing if there are no more results on the next
page. You can customize this output by passing a parameter
:placeholder
.
<%= link_to_next_page @items, 'Next Page', :placeholder => %{<span>No More Pages</span>} %>
# File lib/kaminari/helpers/sinatra_helpers.rb, line 113 def link_to_next_page(scope, name, options = {}) params = options.delete(:params) || (Rack::Utils.parse_query(env['QUERY_STRING']).symbolize_keys rescue {}) param_name = options.delete(:param_name) || Kaminari.config.param_name placeholder = options.delete(:placeholder) query = params.merge(param_name => (scope.current_page + 1)) unless scope.last_page? link_to name, env['PATH_INFO'] + (query.empty? ? '' : "?#{query.to_query}"), options.reverse_merge(:rel => 'next') else placeholder end end
