Active PStore

This library has Active Record like interface. Use pstore to store data.

require 'active_pstore'

ActivePStore::Base.establish_connection(database: '/path/to/file')

class Artist < ActivePStore::Base
  attr_accessor :name
end

randy_rhoads = Artist.new(name: 'Randy Rhoads')

or

randy_rhoads = Artist.new {|a|
  a.name = 'Randy Rhoads'
}

ActivePStore::Base.build method the same as ActivePStore::Base.new method.

randy_rhoads.save

database key is string of class name.

Artist.table_name # => 'Artist'

ex) Fetch stored artist objects by pure PStore.

database = PStore.new('/path/to/file')
database.transaction {|db| artist = db['Artist'] } # fetch instances of Artist class.

allocate value of ActivePStore::Base#id using SecureRandom.hex.

randy_rhoads = Artist.new(name: 'Randy Rhoads')
randy_rhoads.id # => nil

randy_rhoads.save
randy_rhoads.id # => "0b84ece5d5be3bce3ee2101c1c4f6fda"

randy_rhoads = Artist.create(name: 'Randy Rhoads')

or

randy_rhoads = Artist.create {|a|
  a.name = 'Randy Rhoads'
}

Artist.all
Artist.first
Artist.last
Artist.find('388980778246cbcbfcbb7a8292f28c37') # ActivePStore::Base#id is an SecureRandom.hex value
Artist.where(name: 'Randy Rhoads')

Range

Artist.where(birth_date: Date.new(1948, 12, 3)..Date.new(1956, 12, 6))

This library has following generators.

Execute these lines in your Rails application directory:

bundle exec rails g active_pstore:config

And then create config/active_pstore.yml

Using the config/database.yml file you can specify all the information needed to access your pstore database:

development:
  database: db/active_pstore_development.yml

Execute these lines in your Rails application directory:

bundle exec rails g active_pstore:model artist name associated_act instrument birth_date

And then create app/models/artist.rb

class Artist < ActivePStore::Base
  attr_accessor :name
  attr_accessor :associated_act
  attr_accessor :instrument
  attr_accessor :birth_date
end

• Active Model

Add these lines to your application's Gemfile:

gem 'active_pstore'

And then execute:
