@Peege151... I created a working solution with devise integration as said by you..here is my code below, use it for reference purpose. I don't say this is the exact solution for the raised question but this may help since i got it working
Gems:
gem 'rails 3.2.14' # Important~
gem 'devise'
gem 'omniauth'
gem 'omniauth-venmo'
I have not created omniauth.rb in initializers .... instead i added configuration in devise.rb as u wanted it with devise
my devise.rb :
require "omniauth-venmo"
config.omniauth :venmo, '--Your APP KEY -- ', '-- App Secret--',{:client_options => {:ssl => {:verify => false}}}
above line i have set SSL verification to false,, if u want enable SSL with (:verify => true).
This is my callback controller code:
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
def venmo
@user = User.find_for_oauth(request.env["omniauth.auth"], current_user)
if @user.persisted?
sign_in_and_redirect @user, :event => :authentication
set_flash_message(:notice, :success, :kind => "Venmo") if is_navigational_format?
else
session["devise.twitter_uid"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
end
User.rb code:
class User < ActiveRecord::Base
TEMP_EMAIL = 'change@me.com'
TEMP_EMAIL_REGEX = /change@me.com/
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me, :name, :provider , :uid
devise :omniauthable
def self.find_for_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth.provider, :uid => auth.uid).first
if user
return user
else
registered_user = User.where(:email => auth.info.email).first
if registered_user
return registered_user
else
user = User.create(name:auth.extra.raw_info.name,
provider:auth.provider,
uid:auth.uid,
email:auth.info.email.blank? ? TEMP_EMAIL : auth.info.email,
password:Devise.friendly_token[0,20],
)
end
end
user
end
end
Here is my for devise and callback routes.rb:
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
get '/auth/venmo/callback' => 'users/omniauth_callbacks#venmo'
login page link:
<%= link_to "Sign in with Venmo", user_omniauth_authorize_path(:venmo) %>
