Ruby oauth2 grant_type

i started using oauth2 gem with intridea ( http://github.com/intridea/oauth2 ) and don't know how to fix this problem. I have developed both a client and a server, and on request for access_token I do not see the grant_type parameter. My code is from a client callback controller

class CallbackController < Devise::OauthCallbacksController def accounts access_token = accounts_config.access_token_by_code(params[:code]) @user = User.find_for_accounts_oauth(access_token, signed_in_resource) if @user.persisted? && @user.errors.empty? sign_in @user set_oauth_flash_message :notice, :success redirect_to after_oauth_success_path_for(@user) #=> redirects to user_root_path or root_path else session[:user_accounts_oauth_token] = access_token.token render_for_auth #=> renders sign up view by default end end end

and from the user model

 class User < ActiveRecord::Base devise :database_authenticatable, :oauthable def self.find_for_accounts_oauth(access_token, signed_in_resource=nil) data = ActiveSupport::JSON.decode(access_token.get(Settings.oauth.site + Settings.oauth.access_token_path)) if user = User.find_by_username(data["username"]) user else # Create an user with a stub password. User.create!(:username => data["username"], :password => Devise.friendly_token) end end end

The OAuth 2.0 specification has moved since the last update of the oauth2 gem.

Draft 10 and perhaps earlier, use grant_type instead of type , and the values ​​have also changed: authorization_code replaces web_server .

The OAuth 2.0 specification explains more:

http://tools.ietf.org/html/draft-ietf-oauth-v2-10

To solve this problem, it is necessary to update the stone so that it is compatible with a later version of the specification.
