Superstore
Superstore is a PostgreSQL JSONB document store which uses ActiveModel to mimic much of the behavior in ActiveRecord.
Requirements
Superstore requires PostgreSQL 9.5 or above.
Installation
Add the following to the Gemfile:
gem 'superstore'Superstore will share the existing ActiveRecord database connection.
Defining Models
class Widget < Superstore::Base
attribute :name, type: :string
attribute :price, type: :integer
attribute :colors, type: :array
validates :name, presence: :true
before_create do
self.description = "#{name} is the best product ever"
end
endThe table name defaults to the case-sensitive, pluralized name of the model class. To specify a
custom name, set the table_name attribute on the class:
class MyWidget < Superstore::Base
table_name = 'my_widgets'
endCreating and updating records
Superstore has equivalent methods to ActiveRecord:
widget = Widget.new
widget.valid?
widget = Widget.create(name: 'Acme', price: 100)
widget.update_attribute(:price, 1200)
widget.update(price: 1200, name: 'Acme Corporation')
widget.attributes = {price: 300}
widget.price_was
widget.save
widget.save!
