Currently the store does not allow to persist several models because each class writes a 'lazy record.store' and it keeps getting overwritten.

A record should be able to delete itself with record#delete

post = Post.create()
post.delete!
Post.all # Doesn't return the deleted post

When the ::delete method is called on Store, there are a few logs that are generated.

Models attributes should be declarable by using an attribute :attribute_name method inside the model.

So instead of doing:

class Post
  attr_accessor :title, :body

  def initialize(title:, body:)
    @title = title,
    @body = body
  end
end

post = Post.new(title: "Lazyrecord", body:"Body")

You can do:

class Post
  attribute :title
  attribute :body
end

post = Post.new(title: "Lazyrecord", body:"Body")

attribute should take a block to use as default value.

class Post
  attribute :title
  attribute :body
  attribute :created_at { Time.now }
end

post = Post.new(title: "Lazyrecord", body:"Body")
post.title # Lazyrecord
post.body # Body
post.created_at # the result of Time.now

This should be doable following this lesson from RubyMonk
