Superstore
Superstore uses ActiveModel to mimic much of the behavior in ActiveRecord.
Installation
Add the following to the Gemfile
:
gem 'superstore'
Defining Models
class Widget < Superstore::Base
string :name
string :description
integer :price
array :colors, unique: true
validates :name, presence: :true
before_create do
self.description = "#{name} is the best product ever"
end
end
The 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'
end
Using the PostgreSQL JSONB adapter
Add the pg
gem to the Gemfile
:
gem 'pg'
Add a config/superstore.yml
:
development:
adapter: jsonb
Superstore will share the existing ActiveRecord database connection.
Creating and updating records
Superstore has equivalent methods to ActiveRecord:
= Widget.new
.valid?
= Widget.create(name: 'Acme', price: 100)
.update_attribute(:price, 1200)
.update(price: 1200, name: 'Acme Corporation')
.attributes = {price: 300}
.price_was
.save
.save!
Finding records
= Widget.find(uuid)
= Widget.first
= Widget.all
Widget.find_each do ||
# Codez
end
Scoping
Some lightweight scoping features are available:
Widget.where('color' => 'red')
Widget.select(['name', 'color'])
Widget.limit(10)
