Vkontakte OAuth2 provider

[german]

I added an OAuth2 provider for Vkontakte (vkontakte.ru is a major social network in Russia and CIS). They just recently added OAuth2 as an authentication option. I tested it thoroughly on my production site and it works fine.

Vkontakte provider doesn't work for me. I'm testing it on local machine application. I'm registering, configuring app on vk.com and write AppID and AppKey to omniauth.rb. After redirecting from vk.com development.log of my application looks like this:

Started GET "/auth/vkontakte/callback?code=65b06699144b076fff" for 127.0.0.1 at Tue May 03 18:39:32 +0400 2011

NoMethodError (You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]):

@Ssherif could you provide error's traceback please?

yes, I overlooked this scenario, but it seems that user heydiplo already fixed it in his pull request #302

[puffy]

I tried to use latest github version of omniauth, but have the same prtoblem

[german]

yes, it happened because it's not merged into master yet) you could use https://github.com/heydiplo/omniauth for now

[german]

@Ssherif ok, you could use master now: 99a316f

[puffy]

great, it's work!
