Extends Draper by adding pagination and scoping methods

Installation

Add this line to your application's Gemfile:

gem 'draper-extensions'

And then execute:

$ bundle

Or install it yourself as:

$ gem install draper-extensions

Usage

This extension extends these things on the draper gem:

  • Add #decorate to ActiveRecord::Relation.
> listing = Listing.first
> listing.events.decorate
=> #<Draper::CollectionDecorator:0x000001059500f0
 @context={},
 @decorator_class=EventDecorator,
 @object=
  [#<Event id: 1, name: "BugSmash", ar_listing_id: 1, created_at: "2014-05-10 12:43:16", updated_at: "2014-05-10 12:43:16">]>
  • Add #decorate to Kaminari::PaginatableArray.
class Listing
  include Mongoid::Document

  embeds_many   :product_categories

  def products
    @products ||= Kaminari.paginate_array(product_categories.map(&:products))
  end
end

> listing = Listing.first
> listing.products.page(1).decorate
=> #<Draper::CollectionDecorator:0x000001059500f0
 @context={},
 @decorator_class=ProductDecorator,
 @object=
  [#<Product id: 1, name: "Laptop", created_at: "2014-05-10 12:43:16", updated_at: "2014-05-10 12:43:16">]>
  • Add #decorates_scope to Draper::CollectionDecorator.
# app/models/listing.rb
class Listing
  include Mongoid::Document

  field       :name,   type: String

  embeds_many :events
end

# app/models/event.rb
class Event
  include Mongoid::Document

  field       :name,      type: String
  field       :starts_at, type: Time

  scope       :upcomings, -> { where(:starts_at.gt => Time.now) }

  embedded_in :listing
end

# app/decorators/listing_decorator.rb
class ListingDecorator < Draper::Decorator
  decorates_association :events, with: EventsDecorator
end

# app/decorators/events_decorator.rb
class EventsDecorator < Draper::CollectionDecorator
  decorates_scope :upcomings
end

> listing = Listing.first
> listing.decorate.events.upcomings
=> #<EventsDecorator:0x000001016e1ed0
 @context={},
 @decorator_class=EventDecorator,
 @object=
  #<Mongoid::Criteria
  selector: {"starts_at"=>{"$gt"=>2014-05-10 13:03:29 UTC}}
  options:  {}
