Yamlet

Yamlet is a tiny library (< 100 lines of code) which injects CRUD functionalities to your Plain Old Ruby Objects and store data on a YAML file using YAML::Store.

Perfect for creating small applications (for demo/prototyping purposes) where you only need a single YAML file to store everything and removes the constraint of setting up a database.

Add this line to your application's Gemfile:

gem 'yamlet'

And then execute:

$ bundle

Or install it yourself as:

$ gem install yamlet

First, create a YAML file somewhere then tell Yamlet where to find that file which we'll be using for storing data.

Yamlet.repository_file = "/path/to/repository.yml"

NOTE: A RepositoryNotFound error will be raised when Yamlet can't locate the YAML file.

class User
  include Yamlet.model

  #...
end

After including Yamlet.model in your class, notice that the YAML file will automatically be updated.

# /path/to/repository.yml

---
user: []

  User.all   #=> []
  User.create(name: "Grumpy Kid")

  User.all #=> [{"id"=>1, "name"=>"Grumpy Kid"}]

  User.find(1) #=> {"id"=>1, "name"=>"Grumpy Kid"}

  User.create(name: "Grumpy Kid")
  #=> {"id"=>1, "name"=>"Grumpy Kid"}

  User.update(1, name: "Grumpy Dad")
  #=> {"id"=>1, "name"=>"Grumpy Dad"}

  User.destroy(1)

  User.all #=> []

  5.times { |i| User.create(name: "Grumpy #{i}") }

  User.destroy_all #=> []
