Generate and find by UUIDs in ActiveRecord models

This extends shoulda-matchers to allow validating binary uuids in models.

Druuid generates 64-bit, time-sortable UUIDs.

This tool adds the missing UUIDs into the installed Xcode plug-ins so that they can be loaded by newer versions of Xcode.

Bullet Train Has UUID

UUID generator for producing universally unique identifiers based on RFC 4122 (http://www.ietf.org/rfc/rfc4122.txt).

Sequel Model plugin that adds [0-9a-z] unique id prefixed by a custom string.

Add binary (not string) UUIDs to ActiveRecord in MySQL

Helps using uuid everywhere in routes instead of id for ActiveRecord models.

A simple universally unique ID generation library.

在Mongoid实例初始化后自动生成uuid字段。

Simple, scalable UUID generation.

This is a UUID class intended to help control data locality when inserting into a distributed data system, such as MongoDB or HBase. There is also a Java implementation. This version does not conform to any external standard or spec. Developed at Groupon in Palo Alto by Peter Bakkum and Michael Craig.

Support for binary UUIDs in ActiveRecord

Creates UUID version 5 out of scientific name string. It uses globalnames.org domain for DNS namespace. There is a 1:1 relationship between the string and the corresponding UUID, so it allows globally connect data about a name string originated from independent sources without a need to negotiate identifiers.

A UUIDv4 support library

A DataMapper adapter for Amazon's SimpleDB service. Features: * Full set of CRUD operations * Supports all DataMapper query predicates. * Can translate many queries into efficient native SELECT operations. * Migrations * DataMapper identity map support for record caching * Lazy-loaded attributes * DataMapper Serial property support via UUIDs. * Array properties * Basic aggregation support (Model.count("...")) * String "chunking" permits attributes to exceed the 1024-byte limit Note: as of version 1.0.0, this gem supports supports the DataMapper 0.10.* series and breaks backwards compatibility with DataMapper 0.9.*.

Online logging solution (like [Datadog](https://www.datadoghq.com)) have drastically transform the way we log. An app will nowdays logs dozen (hundred) of logs per requests. The issue is often to correlate this logs, with the initiating request (or job) and add shared metadata on this logs. Here come `ContextualizedLogs`. The main idea is to enhance your logs from your controller (including `ContextualizedController`, which use a before action), which will add the params to your logs (and some metadata about the request itself, like `request.uuid`). This metadata are stored in a `ActiveSupport::CurrentAttributes` which is a singleton (reset per request). Each subsequent logs in this thread (request) will also be enriched with this metadata, making it easier to find all the logs associated with a request (`uuid`, `ip`, `params.xxx`). On top of this, logs can also be enriched by the ActiveRecord model they use (`create` or `find`) (models including `ContextualizedModel`). So any time a contextualized model is created or find, some metadata related to the model (`id`, ...) will also be added to the logs. Allowing you to find all logs which "touched" this models.

Useful helpers to consistently migrate Integer id columns to UUID in PostgreSql. Special support for primary keys and references.

The has_uuid gem adds a UUID to your AR models. See the README for details.
