attributes method doesn't behave as specified in the Readme

[alaibe]

Hi This is the readme:

class User
  include Virtus.model

  attribute :name, String
  attribute :age, Integer
  attribute :birthday, DateTime
end

user = User.new(:name => 'Piotr', :age => 31)
user.attributes # => { :name => "Piotr", :age => 31 }

This is from my irb

class User
  include Virtus.model

  attribute :name, String
  attribute :age, Integer
  attribute :birthday, DateTime
end

user = User.new(:name => 'Piotr', :age => 31)
user.attributes # => { :name => "Piotr", :age => 31, :birthday=>nil }

Virtus version: 1.0.5 Ruby version: ruby 2.2.2p95

I would expect attributes to not return the birthday As I am using virtus for form object it causes me problem when I want to do PATCH request

Ruby

user.attributes.delete_if { |k, v| v.nil? }

Rails

user.attributes.compact

Thx for your answer.

Unfortunately it is not enough => you can't set a value to nil with this solution

I already have a workaround to make it works (I can post it if you want)

My question is more: The README is not sync with the behaviour so if

• The readme is correct => then there is a problem that need to be fix
• The current behaviour is correct => I keep my workaround => The readme needs an update

It'd take some effort to add tracking of which attributes have been set to nil and which have not been set. So I'm going to fix the README to match the behavior.
