And then execute:

$ bundle

Usage

config.omniauth :wordpress_oauth2, 'APP_KEY', 'APP_SECRET',
                  strategy_class: OmniAuth::Strategies::WordpressOauth2Plugin, 
                  client_options: { site: 'http://yourcustomwordpress.com' }

Omniauth / Rails

Add provider to your config/initializers/omniauth.rb ex:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :wordpress_oauth2, 'APP_KEY', 'APP_SECRET',
                  strategy_class: OmniAuth::Strategies::WordpressOauth2Plugin, 
                  client_options: { site: 'http://yourcustomwordpress.com' }
end

Add Provider to Wordpress

Asuming you have already installed the wordpress oauth2 provider plugin, add a provider for this rails applicaiton to the plugin configuration:

make sure the callback url you have configured is of the form:

http://your-rails-site.com/users/auth/wordpress_oauth2/callback

Then configure your rails application with the app key and secret generated by the wordpress plugin.

Add callback

Configure routes to add omniauth callbacks controller config/routes.rb (which you implement):

devise_for :users, controllers: { omniauth_callbacks: 'omniauth_callbacks' }

Implement omniauth_callbacks controller app/controllers/omniauth_callbacks_controller.rb :

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def wordpress_oauth2
    #You need to implement the method below in your model (e.g. app/models/user.rb)
    @user = User.find_for_wordpress_oauth2(request.env["omniauth.auth"], current_user)

    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Wordpress Oauth2"
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
    else
      session["devise.wordpress_oauth2_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end
