with_uuid's Introduction

HasUuid

Provides facilities to utilize UUIDs with ActiveRecord, including model and migration extensions.

Installation

Add this line to your application's Gemfile:

gem 'has_uuid'

And then execute:

$ bundle

Or install it yourself as:

$ gem install has_uuid

Usage

In a migration:

create_table "comments", :id => false, :force => true do |t|
  t.uuid     "id",      :primary_key => true 
  t.uuid     "post_id",                       :null => false
end

In a model:

class Posts < ActiveRecord::Base
  include WithUuid::Model

  # ...
end

with_uuid's Issues

adapter_name failure with Rails-4.0.2

Trying to use with_uuid 0.2.0 with rails 4.0.2 and ruby 1.9.3, I built a simple test app model and migration:

class TestModel < ActiveRecord::Base
  include WithUuid::Model
end

class CreateTestModels < ActiveRecord::Migration
  def change
    create_table :test_models, id: false do |t|
      t.uuid :id, primary_key: true
      t.string :name

      t.timestamps
    end
  end
end

But running rake db:migrate results in the following error:

rake db:migrate
==  CreateTestModels: migrating ===============================================
-- create_table(:test_models, {:id=>false})
rake aborted!
An error has occurred, this and all later migrations canceled:
