Provider and UID attributes aren't getting set

[alininja]

Hi,

I tried to follow this tutorial:
https://github.com/intridea/omniauth/wiki/Managing-Multiple-Providers

but came into an issue where the Identity records were getting created with the provider and uid attributes not set.

I'm trying omniauth-identity out on rails 4.0.0.beta1. So my best guess is that strong_parameters aren't allowing these attributes to be mass-assigned? I'm not sure how strong_parameters work with Rack middleware or if I'm just totally off the mark.

The work around for me was to replace:

def self.create_with_omniauth(auth)
  create(uid: auth['uid'], provider: auth['provider'])
end

with something along the lines of

def self.find_and_update_with_omniauth(auth, password)
  identity = find(auth['uid'])
  identity.update_attributes(uid: auth['uid'],
                             provider: auth['provider'],
                             email: auth['info']['email'],
                             password: password)
  identity.save
  identity
end

It's definitely not elegant and I'm not sure if it's solving the root cause of the issue, but just wanted to give you a heads up.

Just out of curiousity, it seems like identity.uid is the same as identity.id. Is it there to keep things consistent with other strategies (since Twitter might pass along a UID that's not tied to an actual record ID)?

Thanks for making such an awesome system!
