A data mapping abstraction over the AWS SDK for Ruby's client for Amazon DynamoDB.

This library is currently under development. More features will be added as we approach general availability, and while our initial release has as small of an API surface area as possible, the interface may change before the GA release.

We would like to invite you to be a part of the ongoing development of this gem. We welcome your contributions, and would also be happy to hear from you about how you would like to use this gem. Feature requests are welcome.

Aws::Record is available as the aws-record gem from RubyGems.

gem install 'aws-record'
gem 'aws-record', '~> 1.0'

This automatically includes a dependency on the aws-sdk-resources gem, major version 2. Be sure to include the aws-sdk or aws-sdk-resources gem in your Gemfile if you need to lock to a specific version, like so:

# Gemfile

gem 'aws-record', '~> 1.0'
gem 'aws-sdk-resources', '~> 2.5'


To create a model that uses aws-record features, simply include the provided module:

class MyModel
  include Aws::Record

You can then specify attributes using the aws-record DSL:

class MyModel
  include Aws::Record
  integer_attr :id, hash_key: true
  string_attr  :name, range_key: true
  boolean_attr :active, database_attribute_name: "is_active_flag"

If a matching table does not exist in DynamoDB, you can use table migrations to create your table.

migration =
  provisioned_throughput: {
    read_capacity_units: 5,
    write_capacity_units: 2

With a table in place, you can then use your model class to manipulate items in your table:

item = MyModel.find(id: 1, name: "Hello Record") = true

MyModel.find(id: 1, name: "Hello Record") # => nil

item = = 2 = "Item" = false
