NullObjectAssociations

Return empty arrays or nil for associations. A nice little addition to null objects. Especially nice for those used in Rails.

Installation

Add this line to your application's Gemfile:

gem 'null_object_associations'

And then execute:

$ bundle

Or install it yourself as:

$ gem install null_object_associations

Usage

class NullUser
  include NullObjectAssociations

  has_many                :friends
  has_many                :cousins,  respond_to: [:pluck, :limit, :order, :completed]
  has_many                :cars,     respond_to: :any
  has_and_belongs_to_many :accounts, respond_to: [:pluck, :completed]
  has_one                 :house
  belongs_to              :spouse
end
