facebook_sign_in_link helper causes NoMethodError in Ruby 1.9.1 about devise_facebook_connectable

That line tries to auto-detect scope. Uhm...without the form you won't get a Devise session, logging in on Facebook is just not enough. What version of Devise you use? Devise moved forward quite fast so the API might have changed, will have a look later on. Use Devise <= 1.0.0, I won't support newer one yet myself as it's built for Rails 3 only and Rails is....beta.

I'm not saying that this line should be removed completely :)
I'm just saying that it should be changed from:
scope = ::Devise::Mapping.find_by_path(request.path).to rescue scope
which for url /users/sign_up returns User class, to:
scope = ::Devise::Mapping.find_by_path(request.path).name rescue scope
which returns :user symbol :)

I edited my original post to include a patch, but it got lost somehow... Here it is again: szimek/devise_facebook_connectable@1fa5b5c

OK, thanks!

Fixed old bug where incorrect scope gets auto-detected. Closed by 2d9b2d7
