Light
When you need all functionalities of ActiveRecord model but for other purposes than db transactions you can use Light. Light has additional equality_state and to_h and persisted? method.
Examples:
require 'light'
class Person < Light::Model
attributes :id, :name, :email
end
person1 = Person.new(name: 'Pawel', email: 'pawel@o2.pl')
person1.to_h # => {"id" => nil, "name"=>"Pawel", "email"=>"pawel@o2.pl"}
person1.as_json # => {"id" => nil, "name"=>"Pawel", "email"=>"pawel@o2.pl"}
person1.to_json # => "{\"id\":null,\"name\":\"Pawel\",\"email\":\"pawel@o2.pl\"}"
person2 = Person.new('name' => 'Pawel', email: 'pawel@o2.pl')
person3 = Person.new(name: 'Sylwia', email: 'sylwia@o2.pl')
person1 == person2 # => true
person1 == person3 # => false
person1.eql?(person2) # => true
person1.eql?(person3) # => false
person1.persisted? # => false
class User < Light::Model
attributes :id, :email
persisted_via_attr :id
end
user = User.new(email: 'somebody@gmail.com')
user.persisted? # => false
user.id = 1
user.persisted? # => trueInstallation
