OpenidRegistrable¶ ↑

OpenidRegistrable is gem for Rails. It makes possible define required and optional fields for registration via OpenID and to map them to fields of your model.

class User < ActiveRecord::Base
  openid_registrable :required_fields => {
      :email => 'http://axschema.org/contact/email',
    },
    :optional_fields => {
      :first_name => 'http://axschema.org/namePerson/first',
      :last_name => 'http://axschema.org/namePerson/last',
    }
end

User.openid_required_fields => ['http://axschema.org/contact/email']
User.openid_optional_fields => ['http://axschema.org/namePerson/first', 'http://axschema.org/namePerson/last']

User.openid_fields_to_model_fields_mapping =>

{:email => 'http://axschema.org/contact/email'
 :first_name => 'http://axschema.org/namePerson/first',
 :last_name => 'http://axschema.org/namePerson/last'
}

# assign fields
@user = User.new
@user.assign_openid_fields(openid_ax_data)
@user.save
