mongoid-siblings

mongoid-siblings adds methods to enable you to easily access your Mongoid document's siblings.

• mongoid (~> 3.0)

Add the following to your Gemfile:

gem "mongoid-siblings", require: "mongoid/siblings"

And tell Bundler to install the new gem:

bundle install

Include the Mongoid::Siblings module in your document class:

class Book
  include Mongoid::Document
  include Mongoid::Siblings

  belongs_to :publisher
  belongs_to :author

  ...
end

You will now have access to the following methods:

# Find all books by this book's author, not including this book.
book.siblings(scope: :author)

# Find all books by this book's author.
book.siblings_and_self(scope: :author)

# Check whether a certain book was published by the same publisher as this book.
book.sibling_of?(other_book, scope: :publisher)

# Make this book a sibling of a book with another author and publisher.
# This will set this books author and publisher to match that of the other book.
book.become_sibling_of!(other_book, scope: [:author, :publisher])
