Devise << RPX by Nicolas Blanco
A great authentication gem for Rails applications.
http://github.com/plataformatec/devise
RPX (now called Janrain Engage) is a Software as a Service (SaaS) that helps you manage multiple authentication methods (FacebookConnect, Google, Twitter, OpenID, MySpace…) using a single API.
It also provides a multilingual connection widget.
Instead of managing multiple authentication providers and APIs, you just need to handle one.
Janrain Engage provides free and paid accounts.
See Janrain Engage official homepage. If you want to see what it looks like, you may signup on the Janrain Engage website as it uses Engage for signup :).
Devise RPX Connectable is a gem to integrate Janrain Engage authentication in a Rails application using Devise.
Please note that this is an unofficial library. It is neither affiliated with, nor endorsed by Janrain Inc.
Devise RPX Connectable should be compatible with the latest Rails and Devise versions (currently Rails 3.0+ and Devise 2.1.2+).
IMPORTANT : This gem is now ONLY COMPATIBLE with Rails 3, if you want to use it with Rails 2, please use version 0.1.3.
As usual… Add gem "devise_rpx_connectable" in your Gemfile…
Devise: Setup
See Devise documentation for instructions on how to setup Devise.
Devise: Model
Add :rpx_connectable in your Devise model (ie. User.rb)
devise ..., :rpx_connectable
Devise:Setup
In the Devise initializer (may be config/initializers/devise.rb) :
Devise.setup do |config|
...
config.rpx_application_name = "mytestingapp" # The name of your RPX application (this is the name, NOT the API key!)
end
RPXNow:API Key
In config/application.rb or config/environments/YOUR_ENV.rb (to set a different key for each environment…) :
...
RPXNow.api_key = "aaaabbbbbccccdddddeeeeefffff"
...
Migrations
Your model needs one attribute/column to store the RPX identifier. By default, this identifier is rpx_identifier.
So don’t forget to add that field to your model (using a migration or whatever…).
Views
The RPX connection widget can be added in your application using a link or an iframe.
If you choose to use a link, the connection widget can be displayed in a new page (standard link) or using Javascript in overlay.
I added an easy to use helper to add a link to the RPX connection popup.
<%= link_to_rpx "Signin using RPX!", user_session_url %>
If you use the link alone, users will be redirected to a new page.
If you want the more sexy popup in overlay, you need to add the JS code before the </body> of your layout.
An helper is also included for this task :
...
<%= javascript_include_rpx(user_session_url) %>
</body>
</html>
If you want to display the connection widget in an iframe inside a page :
<%= embed_rpx user_session_url %>
There is some advanced features that you may use…
Devise:Setup
Devise.setup do |config|
...
config.rpx_auto_create_account = true # false if you don't want to create users automaticaly. True by default.
config.rpx_additional_user_data = [:verifiedEmail, :url, :providerName,:photo] # default [], get some extra profile info from RPXnow, default only a few fields are available in the rpx_user object (https://rpxnow.com/docs#profile_data)
config.rpx_extended_user_data = true # false by default, extended data only available for Plus and Pro RPX users (https://rpxnow.com/docs#api_auth_info)
end
Devise:Model
There are two hooks that you may define in your model : before_rpx_success (called before each successful connection) and before_rpx_auto_create (called only once before the auto saving of the user instance, when rpx_auto_create_account is enabled).
You get in parameter the RPX User object from the RPXNow gem which is basically a Hash containing more or less information depending on your RPX configuration and account.
Read the RPXNow gem documentation for more information about this…
def before_rpx_success(rpx_user)
# Do something with rpx_user...
end
def before_rpx_auto_create(rpx_user)
# Do something with rpx_user
end
- Handle RPX multiple accounts mapping?
The base of this gem was heavily inspired from the Devise Facebook Connectable gem by Jonas Grimfelt and other Devise gems.
This gem also uses the great rpx_now by Michael Grosser
