= Kaminari
A Scope & Engine based clean and powerful and customizable and sophisticated paginator for Rails 3
== Features
* Clean
Does not globally pollute Array, Hash, Object or AR::Base.
* Easy to use
Just bundle the gem, then your models are ready to be paginated. No configuration. Don't have to define anything in your models or helpers.
* Scope based simple API
Everything is method chainable with less Hasheritis. You know, that's the Rails 3 way.
No special collection class or something for the paginated values but uses a general AR::Relation instance. So, of course you can chain any other conditions before or after the paginator scope.
* Engine based customizable helper
As the whole pagination helper is basically just a collection of links and non-links, Kaminari renders each of them through its own partial template inside the Engine. So, you can easily modify their behaviour or style or whatever by overriding partial templates.
* Modern
The pagination helper outputs the HTML5 <nav> tag by default. Plus, the helper supports the Rails 3 unobtrusive Ajax.
== Rails versions
3.0.x and 3.1
== Install
Put this line in your Gemfile:
gem 'kaminari'
Then bundle:
% bundle
== Usage
=== Query Basics
* Fetch the 7th page of the users (per_page = 25 by default)
User.page(7)
* Show a lot more users per each page (change the per_page value)
User.page(7).per(50)
=== Controllers
* Typically, your controller code will look like this:
@users = User.order(:name).page params[:page]
=== Views
* Just call the "paginate" helper
<%= paginate @users %>
This will render several "?page=N" pagination links surrounded by an HTML5 <nav> tag.
=== Helper Options
* Specifing the "inner window" size (4 by default)
<%= paginate @users, :window => 3 %>
* Specifing the "outer window" size (1 by default)
<%= paginate @users, :outer_window => 3 %>
* outer window can be separetely specified by "left", "right" (1 by default)
<%= paginate @users, :left => 0, :right => 2 %>
* Ajax links (crazy simple, but works perfectly!)
<%= paginate @users, :remote => true %>
=== Customizing the pagination helper
* The generator
% rails g kaminari:views
Then edit the partials in your app's app/views/kaminari/ directory.
* For Haml users
Haml templates generator is also available by adding "-e haml" option.
% rails g kaminari:views -e haml
