Sinatra::Pagin*

Small utility to process paginated urls without modifying the mapped paths in your Sinatra app

Overview/Usage:

Basics:

Given you have mapped paths as such:

get "/" do
  "hello world"
end
#=> "http://example.org/"

get "/a/pathed/path" do
  "foo bar"
end
#=> "http://example.org/a/pathed/path"

Without changing those paths, you can run a paginated url.

require 'sinatra/pagin
Sinatra::Application.register Sinatra::Pagin

http://example.org/page/2
# => get "/"

http://example.org/a/pathed/path/page/45
# => get "/a/pathed/path"

*This is based on "pretty" style urls, page parameters sent in via the query string (.../?page=2) will be processed by Sinatra's usual params.

Helpers:

page returns the parsed "page" number.

http://example.org/page/2

get "/" do
  "hello world, you asked for page #{page}"
end
# => hello world, you asked for page 2

page returns 1 as a default.

href_for_pagin(total_pages, direction => :next) href builder to build pagin valid hrefs for next & previous links based on the currently requested uri.

• total_pages => Integer (Required)
• direction => Symbol [:next | :prev] (Defaults to => :next)

---

http://example.org/2009/10/page/2

href_for_pagin 4, :next
#=> /2009/10/page/3

href_for_pagin 4, :prev
#=> /2009/10/page/1

Additional notes:

It also supports .:format in your path.

get "/a/pathed/path.:format" do
  "foo bar"
end

http://example.org/a/pathed/path/page/45.js
# => path_info == /a/pathed/path.js
# => page == 45
