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
|
|
|
|
* the :page scope
|
|
To fetch the 7th page of the users (per_page = 25 by default)
|
|
User.page(7)
|
|
|
|
* the :per scope
|
|
To show a lot more users per each page (change the per_page value)
|
|
User.page(7).per(50)
|
|
Note that the :per scope is not directly defined on the models but is just a method defined on the page scope. This is absolutely reasonable because you will never actually use "per_page" without specifying the "page" number.
|
|
|
|
=== Controllers
|
|
|
|
* the page parameter is in params[:page]
|
|
Typically, your controller code will look like this:
|
|
@users = User.order(:name).page params[:page]
|
|
|
|
=== Views
|
|
|
|
* the same old helper method
|
|
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)
|
|
This would output something like ... 5 6 7 8 9 ... when 7 is the current page.
|
|
<%= paginate @users, :window => 2 %>
|
|
|
|
* specifing the "outer window" size (1 by default)
|
|
This would output something like 1 2 3 4 ...(snip)... 17 18 19 20 while having 20 pages in total.
|
|
<%= paginate @users, :outer_window => 3 %>
|
|
|
|
* outer window can be separetely specified by "left", "right" (1 by default)
|
|
This would output something like 1 ...(snip)... 18 19 20 while having 20 pages in total.
|
|
<%= paginate @users, :left => 0, :right => 2 %>
|
|
|
|
* Ajax links (crazy simple, but works perfectly!)
|
|
This would add data-remote="true" to all the links inside.
|
|
<%= paginate @users, :remote => true %>
|
|
|
|
=== Customizing the pagination helper
|
|
|
|
Kaminari includes a handy template generator.
|
|
|
|
* to edit your paginator
|
|
Run the generator first,
|
|
% rails g kaminari:views default
|
|
|
|
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 (this would actually be automatically invoked while the default template_engine is set to Haml).
|
|
|
|
% rails g kaminari:views default -e haml
|
|
|
|
* themes
|
|
Kaminari is shipped with template themes in addition to the "default" one, which will help you creating a nice looking paginator.
|
|
% rails g kaminari:views THEME
|
|
|
|
To see the full list of avaliable themes, just hit the generator without specifying THEME argument.
|
|
% rails g kaminari:views
