Billfold

Billfold provides backend Rails support for OmniAuth. Specifically, it routes /auth/:provider/callback to Billfold::IdentitiesController#update_or_create, which handles updating and creating user identities from OmniAuth hashes. It also provides GET /identities and DELETE /identities/:id for users to manage the identities attached to their account.

Requirements

• Rails 3.x

Installation

1. Add gem 'billfold' to your Gemfile
2. Run bundle (or bundle install)
3. Run rails g billfold:migration if you're using Rails migrations

Configuration

With ActiveRecord

If you don't have User and Identity model classes, run rails g billfold:models to create them. Otherwise, include Billfold::ActiveRecordUser and Billfold::ActiveRecordIdentity in them respectively. You may wish to define User#perform_additional_merge_operations! if you need to do additional logic during a user merge.

Without ActiveRecord

Include Billfold::User and Billfold::Identity in the model classes. You'll also have do define the following methods:

• User.find_by_id(id)
• User#merge_into!(other_user)
• Identity.with_provider_and_value(provider, value)
• Identity#user
• Identity#update_attributes!
• Identity#save!

Classes

In either case, if you want to use something other than User and Identity for your classes, you can, but you have to tell Billfold. You can do that like so:

Billfold.user_class_name = 'My::User'
Billfold.identity_class_name = 'My::UserIdentity'

Internationalization

See config/locales/en.yml for a list of keys that must be translated to make the models, views, and controllers fully internationalized.
