RailsMatchingGem

Use this gem to match attributes between your object instances. It basically returns the percentage of attributes matched between two instances.

Add this line to your application's Gemfile:

gem 'rails_matching'

And then execute:

$ bundle install

	# Matches all instances from a model with same model
	# Returns object id, object id that id matched against, and percentage of match
	RailsMatching.against_itself(User.all)
	# [ [1, 2, 33.0 ]
	#   [1, 3, 0.0 ]
	#   [1, 4, 88.0 ] ]

	# Matches one instance from a model with all instances from same model
	# Returns object id, object id that id matched against, and percentage of match
	instance = User.create(name: "Test", age: 22, job_title: "writer")
	RailsMatching.instance_against_all(instance, User.all)
	# You can also exclude attributes from match
	RailsMatching.instance_against_all(instance, User.all, exclude_attrs: ["name"])

• Use of required fields

• Instance against instance method
• Specs
• Use of SQL queries for large data sets
• Add order method
• Add max filter to return a max number of instances
