Answer 1

Su método find_for_facebook_oauth está implícitamente vuelve nula en los casos en que se encuentre un modelo. Debería devolver explícitamente el modelo si lo encuentra en su lugar.

def self.find_for_facebook_oauth(auth, signed_in_resource=nil) 
    model = Model.where(:provider => auth.provider, :uid => auth.uid).first 
    return model if model 
    model = Model.create(name:auth.extra.raw_info.name, 
         provider:auth.provider, 
         uid:auth.uid, 
         email:auth.info.email, 
         password:Devise.friendly_token[0,20] 
         ) 
end

def self.find_for_facebook_oauth(auth, signed_in_resource=nil) 
    model = Model.where(:provider => auth.provider, :uid => auth.uid).first 
    unless model 
    model = Model.create(name:auth.extra.raw_info.name, 
        provider:auth.provider, 
        uid:auth.uid, 
        email:auth.info.email, 
        password:Devise.friendly_token[0,20] 
        ) 
    end
