Kaminari Cache

This gem is no longer maintained, and I wouldn’t even recommend you use it!

Kaminari Cache makes caching your Kaminari pagination a breeze

• RedisStore for Redis
• DalliStore for Memcached
  • Note that you will need the dalli-store-extensions gem because kaminari-cache makes use of the delete_matched method which is not in dalli gem

When using an unsupported cache engine, the entire cache will be flushed when editing a record.

Add this line to your application's Gemfile:

gem 'kaminari-cache'

In your controller, simply call Model.fetch_page (instead of Model.page) with an options hash containing :page, :per & :order.

:order can be a Symbol, a Hash or a String depending on your sorting needs.

In your controller:

  @events = Event.fetch_page :page => (params[:page] || 1),
                   :per => 18,
                   :order => {
                     :start => :desc,
                     :updated_at => :desc
                   }
                   # :locale => :fr,
                   # :scope => :latest,
                   # :includes => :occurrences

In your view:

  @events.each do |entry|
    # Do your thing
  end

Note that fetch_page returns an array of type Kaminari::PaginatableArray so if you use something like Draper which decorates ActiveRecord collections, you'll need to decorate them manualy and delegate the needed methods:

In an initializer (config/initializers/draper.rb):

  Draper::CollectionDecorator.delegate :current_page, :total_pages, :limit_value, :total_count

In your controller:

  @events = Draper::CollectionDecorator.new Event.fetch_page(...)

• Testing!
• More cache engines

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
• Fork the project.
• Start a feature/bugfix branch.
• Commit and push until you are happy with your contribution.
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
