DynamoRecord

A simple DynamoDB ORM wrapper on top of aws-sdk v2

Add this line to your application's Gemfile:

gem 'dynamo_record'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dynamo_record

To create a model with DynamoRecord, simply include the DynamoRecord::Document mixin in your class as such::

class User
  include DynamoRecord::Document
end

Declaring a field is done by using the field method. For example, the following defines a User model with a first and last name:

class User
  include DynamoRecord::Document

  field :first_name, :string
  field :last_name, :string
end

field accepts the following options:

• :default to specify a default value
• :hash_key to specify a DynamoDB hash key
• :range_key to specify a DynamoDB range key
• :index to specify an index

DynamoRecord provides a similar persistence interface compared to other ORMs.

user = User.new(first_name: 'John', last_name: 'Doe')
user.save

user = User.create(first_name: 'John', last_name: 'Doe')

user.destroy

users = User.all

users = User.where(first_name: 'John')

users = User.where(first_name: 'John', limit: 5)

user = User.find('f9b351b0-d06d-4fff-b8d4-8af162e2b8ba')
