Ruby on rails 无法在请求之间保留新对象-RoR

在我的应用程序中，我有一个twitter和facebook登录名，但是在他们首次注册twitter或facebook后，我需要提示密码和电子邮件。我正在使用omniauth gems，我的控制器/用户模型如下所示：

    //socials_controller.rb
    def create
        #render text: request.env['omniauth.auth'].to_yaml and return
        @user = User.from_omniauth(request.env['omniauth.auth'])
        if(@user.email == nil)
          redirect_to patient_login_entry_url(@user)
        elsif @user.confirmed
          log_in @user
          redirect_to @user
        else
          flash[:danger]  = "Bir hata olustu."
          redirect_to root_url
        end
      end

 def login_entry
    @patient = Patient.find(params[:id])
  end

  def update_social
    @patient = Patient.find(params[:id])
    if @patient.update_attributes(user_params)
      SendVerificationEmailJob.perform_later @patient
      flash[:success]  = "Aktivasyon için #{@patient.email} adresinizi kontrol ediniz."
      redirect_to root_url
    else
      flash[:danger]  = "Bilgilerinizi kontrol edip tekrar deneyiniz."
      redirect_to patient_login_entry_url(@patient)
    end
  end

我的from_omniauth方法是：

//user.rb
has_secure_password
class << self
    def from_omniauth(auth_hash)
      if exists?(uid: auth_hash['uid'])
        user = find_by(uid: auth_hash['uid'])
      else
        user = find_or_create_by(uid: auth_hash['uid'], provider: auth_hash['provider'], type: 'Patient')
        user.location = get_social_location_for user.provider, auth_hash['info']['location']
        if auth_hash.provider == 'facebook'
          user.avatar = User.process_uri(auth_hash['info']['image'])
          user.name = auth_hash['extra']['raw_info']['first_name']
          user.surname = auth_hash['extra']['raw_info']['last_name']
          user.email = auth_hash['extra']['raw_info']['email']
          user.gender = auth_hash['extra']['raw_info']['gender']
        elsif auth_hash.provider == 'twitter'
          user.avatar = auth_hash['info']['image']
          user.name = auth_hash['info']['name']
        end
        user.url = get_social_url_for user.provider, auth_hash['info']['urls']
        user.save!
      end
      user
    end

//user.rb
有安全的密码吗
类，您可以使用
user.save保存它并绕过变量！（validate:false）
您可以在两个请求之间的会话中存储密码。
