ruby-on-rails – 使用omniauth时设计跳过确认

如何更改以下代码,以便登录Facebook的用户可以通过设计确认跳过确认？我尝试添加user.skip_confirmation！在user.email行下…但是这不起作用.

user.rb：

# Finds or creates user based on omniauth hash from given provider
  def self.from_omniauth(auth)
    where(provider: auth.provider,uid: auth.uid).first_or_create do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      user.first_name = auth.info.first_name
      user.last_name = auth.info.last_name
      user.email = auth.info.email
    end
  end

  # Overrides class method 'new_with_session' to persist and validate attributes
  def self.new_with_session(params,session)
    if session["devise.user_attributes"]
      new(session["devise.user_attributes"],without_protection: true) do |user|
        user.attributes = params
        user.valid?
      end
    else
      super
    end
  end

omn​​iauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController

  def all
    user = User.from_omniauth(request.env["omniauth.auth"])
    if user.persisted?
      flash.notice = "Signed in!"
      sign_in_and_redirect user
    else  
      session["devise.user_attributes"] = user.attributes
      redirect_to new_user_registration_url
    end
  end
  alias_method :facebook,:all
end

解决方法

尝试使用first_or_initialize：

def self.from_omniauth(auth)
    where(provider: auth.provider,uid: auth.uid). first_or_initialize do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      user.first_name = auth.info.first_name
      user.last_name = auth.info.last_name
      user.email = auth.info.email
      user.skip_confirmation!
      user.save!
    end
  end
