PageAdams

ActiveRecord model pagination made easy.

Add this line to your application's Gemfile:

gem 'page_adams'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install page_adams

Include PageAdams in every model you want to paginate

class Article < ApplicationRecord
  include PageAdams
end

That's it. Now you can call Article.page 5 to get the fifth page of paginated results.

page returns a hash with the following structure:

> Article.page 1
=> {:records=>#<ActiveRecord::Relation [#<Article id: 1>]>, :current_page=>1, :total_pages=>4}

in wich

• the :records key holds an array of instances (or empty) (ActiveRecord::Relation)
• the :current_page key holds the current retrieved page (Integer)
• the :total_pages key holds the total number of instances pages (Integer)

You can also specify the page size per method call

> pagination = Article.page(1, 7)
> pagination[:records].size
=> 7

At the moment, only page_size can be configured. Create 'config/initializers/page_adams.rb' and write

PageAdams.setup do |config|
  config.page_size = 7
end

A basic suite of tests has been included into the gem, using RSpec. Clone the project, enter the folder and run rspec.
