Facebooker2如何保存一個新的註冊？

Question

我正在使用facebooker2（Rails 2.3和RESTFUlL身份驗證）進行facebook連接功能。在我的控制器中，我使用這個動作：

def create_facebook_user 
    if current_facebook_user 
     @user = User.find_by_fb_user_id(current_facebook_user.id.to_i) 
    end 
    if @user.blank? 
     @facebook_user = current_facebook_user.fetch 

     @user = User.new :login => @facebook_user.email, :email => @facebook_user.email, :name => @facebook_user.name 
     @user.fb_user_id = @facebook_user.id.to_i 
     @user.state = "active" 

     if @user.save(:validate=> false) 
     @user.profile = Profile.create(:benefactor_id => nil, :benefactor_invites => Setting.find_by_identifier("benefactor_invites").value.to_i) 
     redirect_to :controller => "profiles", :action => "show", :id => @user.profile.id 
     else 
     render "new" 
     end 
    elsif @user.fb_user_id.nil? 
     @user.update_attribute :fb_user_id, current_facebook_user.id 
     redirect_to :controller => "dashboard", :url => "index" 
    else 
     redirect_to :controller => "dashboard", :url => "index" 
    end 

然後我的問題是給用戶分配狀態。當用戶使用save方法@ user.save（：validate => false）時，它不會「跳過」驗證器。另外我修改了一個RESTFul認證模塊「ByPassword」的方法password_required，但保存方法返回false。

我後我的代碼

Controller 

    class UsersController < ApplicationController 
     skip_before_filter :verify_authenticity_token, :only => :create 

     before_filter :find_user, 
        :only => [:profile, 
           :destroy, 
           :edit_password, :update_password, 
           :edit_email, :update_email] 

     layout 'application' 
     def create_facebook_user 
     if current_facebook_user 
      @user = User.find_by_fb_user_id(current_facebook_user.id.to_i) 
     end 
     if @user.blank? 
      @facebook_user = current_facebook_user.fetch 

      @user = User.new :login => @facebook_user.email, :email => @facebook_user.email, :name => @facebook_user.name 
      @user.fb_user_id = @facebook_user.id.to_i 
      @user.state = "active" 

      if @user.save(:validate=> false) 
      @user.profile = Profile.create(:benefactor_id => nil, :benefactor_invites => Setting.find_by_identifier("benefactor_invites").value.to_i) 
      redirect_to :controller => "profiles", :action => "show", :id => @user.profile.id 
      else 
      render "new" 
      end 
     elsif @user.fb_user_id.nil? 
      @user.update_attribute :fb_user_id, current_facebook_user.id 
      redirect_to :controller => "dashboard", :url => "index" 
     else 
      redirect_to :controller => "dashboard", :url => "index" 
     end 
     end 

end

Answer 1

首先我使用save_with_validations（ActiveRecord的假）方法，然後我用正常保存方法
