Relaxo Model

Relaxo Model provides a framework for business logic on top of Relaxo, a document data store built on top of git. While it supports some traditional relational style patterns, it is primary focus is to model business processes and logic at the document level.

Here is a simple example of a traditional ORM style model:

require 'relaxo/model'

database = Relaxo.connect("test")

trees = [
	{:name => 'Hinoki', :planted => Date.parse("2013/11/17")},
	{:name => 'Keyaki', :planted => Date.parse("2016/9/24")}
]

class Tree
	include Relaxo::Model
	
	property :id, UUID
	property :name
	property :planted, Attribute[Date]
	
	view :all, [:type], index: [:id]
end

database.commit(message: "Create trees") do |changeset|
	trees.each do |tree|
		Tree.insert(changeset, tree)
	end
end

database.current do |dataset|
	Tree.all(dataset).each do |tree|
		puts "A #{tree.name} was planted on #{tree.planted.to_s}."

		# Expected output:
		# A Hinoki was planted on 2013-11-17.
		# A Keyaki was planted on 2016-09-24.
	end
end

#!/usr/bin/env ruby

gem 'relaxo'

require 'relaxo/model'

database = Relaxo.connect("test")

trees = [
	{:name => 'Hinoki', :planted => Date.parse("2013/11/17")},
	{:name => 'Keyaki', :planted => Date.parse("2016/9/24")}
]

class Tree
	include Relaxo::Model

	property :name
	property :planted, Attribute[Date]

	view :all, [:type], index: [:name]
end

database.commit(message: "Create trees") do |changeset|
	trees.each do |tree|
		Tree.insert(changeset, tree)
	end
end

database.current do |dataset|
	trees.each do |tree|
		object = Tree.fetch_all(dataset, name: tree[:name])
		puts object
	end
end
