Spree Social

Core for all social media related functionality for Spree. The Spree Social gem handles authorization, account creation and association through social media sources such as Twitter and Facebook. This gem is beta at best and should be treated as such. Features and code base will change rapidly as this is under active development. Use with caution.

Setup for Production

Add this extension to your Gemfile with this line:

Spree >= 3.1

gem 'spree_social', github: 'spree-contrib/spree_social'

Spree 3.0 and Spree 2.x

gem 'spree_social', github: 'spree-contrib/spree_social', branch: 'X-X-stable'

The branch option is important: it must match the version of Spree you're using. For example, use 3-0-stable if you're using Spree 3-0-stable or any 3.0.x version.

Install the gem using Bundler:

bundle install

Copy & run migrations

bundle exec rails g spree_social:install

Restart your server

If your server was running, restart it so that it can find the assets properly.

Preference(optional): By default url will be /users/auth/:provider. If you wish to modify the url to: /member/auth/:provider, /profile/auth/:provider, or /auth/:provider then you can do this accordingly in your config/initializers/spree.rb file as described below:

Spree::SocialConfig[:path_prefix] = 'member'  # for /member/auth/:provider
Spree::SocialConfig[:path_prefix] = 'profile' # for /profile/auth/:provider
Spree::SocialConfig[:path_prefix] = ''        # for /auth/:provider

Spree Setup to Utilize OAuth Sources

Click on the New Authentication Method button to enter the key obtained from their respective source, (See below for instructions on setting up the various providers).

Multiple key entries can now be entered based on the rails environment. This allows for portability and the lack of need to check in your key to your repository. You also have the ability to enable and disable sources. These setting will be reflected on the client UI as well.

Alternatively you can ship keys as environment variables and create these Authentication Method records on application boot via an initializer. Below is an example for facebook.

# Ensure our environment is bootstrapped with a facebook connect app
if ActiveRecord::Base.connection.table_exists? 'spree_authentication_methods'
  Spree::AuthenticationMethod.where(environment: Rails.env, provider: 'facebook').first_or_create do |auth_method|
    auth_method.api_key = ENV['FACEBOOK_APP_ID']
    auth_method.api_secret = ENV['FACEBOOK_APP_SECRET']
    auth_method.active = true
  end
end

You MUST restart your application after configuring or updating an authentication method.

Setup the Applications at the Respective Sources

OAuth Applications @ Facebook, Twitter and / or Github are supported out of the box but you will need to setup applications are each respective site as follows for public use and for development.

All URLs must be in the form of domain.tld you may add a port as well for development

Facebook

Facebook / Developers / Apps

Name the app what you will and agree to the terms.
Fill out the capcha
Under the Web Site tab
Site URL: http://your_computer.local:3000 for development / http://your-site.com for production
Site domain: your-computer.local / your-site.com respectively

Twitter

Twitter / Application Management / Create an application

Name and Description must be filled in with something
Application Website: http://your_computer.local:3000 for development / http://your-site.com for production
Application Type: Browser
Callback URL: http://your_computer.local:3000 for development / http://your-site.com for production
Default Access Type: Read & Write
Save Application

Github

Github / Applications / Register a new OAuth application

Name The Application
Main URL: http://your_computer.local:3000 for development / http://your-site.com for production
Callback URL: http://your_computer.local:3000 for development / http://your-site.com for production
Click Create

This does not seem to be a listed Github item right now. To View and / or edit your applications goto http://github.com/account/applications

Amazon

Amazon / App Console / Register a new OAuth application

Register New Application
Name the Application, provide description and URL for Privacy Policy
Click Save
Add Your site under Web Settings > Allowed Return URLs (example: http://localhost:3000/users/auth/amazon/callback)

The app console is available at https://login.amazon.com/manageApps

Other OAuth sources that are currently supported

Google (OAuth)

Adding other OAuth sources

It is easy to add any OAuth source, given there is an OmniAuth strategy gem for it (and if not, you can easily write one by yourself. For instance, if you want to add authorization via LinkedIn, the steps will be:

1, Add gem "omniauth-linkedin" to your Gemfile, run bundle install.

2, In an initializer file, e.g. config/initializers/devise.rb, add and init a new provider for SpreeSocial:

Optional: If you want to skip the sign up phase where the user has to provide an email and a password, add a third parameter to the provider entry and the Spree user will be created directly using the email field in the Auth Hash Schema:

SpreeSocial::OAUTH_PROVIDERS << ['LinkedIn', 'linkedin', 'true']
SpreeSocial.init_provider('linkedin')

3, Activate your provider as usual (via initializer or admin interface).

4, Override spree/users/social view to render OAuth links in preferred way for a new one to be displayed. Or alternatively, include to your CSS a definition for .icon-spree-linkedin-circled and an embedded icon font for LinkedIn from fontello.com (the way existing icons for Facebook, Twitter, etc are implemented). You can also override CSS classes for other providers, .icon-spree-<provider>-circled, to use different font icons or classic background images, without having to override views.
