Question

I tried to follow https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview, but somehow when I look at the generated routes I only see the callback path, and not the authorization path (and indeed I get the error on the view with the user_omniauth_authorize_path link).

I assume it might be a versions issue of OmniAuth and Devise (since after 0.2.0.beta Omniath allows configurable setting, and the routes must be defined). However, when trying to use an older OmniAuth version I get the error “You are using an old OmniAuth version, please ensure 0.2.0.beta or later installed.“.

I tried working with Devise’s master, 1.2.rc and the the omniauth branch and with both the entire omniauth gem (after 0.2.0.beta) and with ‘oa-oauth’ but without success.
I also tried to define the route:

match '/users/auth/:action/', :to => 'users/omniauth_callbacks#action', :as => 'user_omniauth_authorize'

This helped with the route, but when pressing the link I did get the error that devise cannot find a mapping. Funny enough, changing the controller in the devise_for to be invalid (like adding ‘/’ before the users/omniauth_callbacks) resulted in an error the first time (“Controller name should not start with a slash”), but a small reload actually sent me to facebook and back (but naturally the callback route was not defined).

I am new to Ruby, and not quite sure where I go from here. Any help will be appreciated.

Answer 1

My problem was due to different versions of omniauth and devise. What finally worked was using this configuration in my gemfile:

gem 'devise', :git => 'git://github.com/plataformatec/devise.git'
gem 'omniauth', '>=0.2.0.beta'
gem 'oa-oauth', :require => 'omniauth/oauth'
