Relationship to ActiveModel::Atributes

[jaredbeck]

It seems that in 2017 the Attributes API was implemented in ActiveModel.

Should we add something to the readme here explaining when to use this gem, vs. ActiveModel::Atributes?

@jaredbeck Yeah, that would definitely be a good idea

I wanted to document here because every few months I remember I have this question and have been a longtime user and copy-paster-into-new-projects of this active_model_attributes gem.

It seems like it's possible to use ActiveModel::Attributes directly. E.g. this works for me without usage of this gem:

class Person 
  include ActiveModel::Model # necessary to initialize with values e.g. `Person.new(name: "Alice")`
  include ActiveModel::Attributes
  
  attribute :name, :string
end

person = Person.new
person.name = 'Alice'
person.name # => Alice

Why (now) would I use this gem, vs. ActiveModel::Attributes?

@bensheldon Now there is not much reason to use it actually if you have a proper version of Rails. This API was not available in ActiveModel for some time, but I think since 5.2 it's been part of Rails already.
