active-dynamo

An ActiveRecord like ODM for AWS DynamoDB

Installation

gem install active-dynamo

Usage

Currently, the supported operations are as follows:

• Define a model in a way similar to ActiveRecord, calling table_name and attributes functions:

class Account < ActiveDynamo::Base
  table name: 'account', partition_key: :no, sort_key: :balance
  attributes no: Integer, balance: Integer, kind: String
end

• Create a new record:

account = Account.new(no: 123, balance: 2000, kind: 'current')
account.save

# or use `create`
account = Account.create(no: 123, balance: 2000, kind: 'current')

• Query the table using methods such as:

Account.all

Account.where(no: 123, balance: 2000)
Account.where("no = 123 and balance >= 2000 and kind = 'current'")

Account.find(no: 123, balance: 2000)

• Update a record

account = Account.first
account.update(kind: 'savings')

• Delete a record

Account.destroy(no: 123, balance: 2000)
