每当我在通过 Google 登录时尝试更新名字和姓氏时，它都会更新值。但是当我重新登录时，它显示旧值（以前的值没有保存）。

这是我的代码：

  def self.create_user_for_google(data)      
    where(uid: data['email']).first_or_initialize.tap do |user|
      user.provider = 'google_oauth2'
      user.uid = data['email']
      user.first_name = data['given_name']
      user.last_name = data['family_name']
      user.avatar = data['picture']
      user.email = data['email']
      user.password = Devise.friendly_token[0, 20]
      user.password_confirmation = user.password
      user.save!
    end
  end

登录时的终端日志：

User Load (13.3ms)  SELECT  "users".* FROM "users" WHERE "users"."uid" = $1 ORDER BY "users"."id" ASC LIMIT $2  [["uid", "shrijana460@gmail.com"], ["LIMIT", 1]]

尝试以下操作：

where(uid: data['email']).first_or_create do |user|
  user.provider = 'google_oauth2'
  user.first_name = data['given_name']
  user.last_name = data['family_name']
  user.avatar = data['picture']
  user.email = data['email']
  user.password = Devise.friendly_token[0, 20]
  user.password_confirmation = user.password
end

您的实现会在每次通过 Google 登录时使用旧数据更新用户

where(uid: data['email']).first_or_initialize.tap do |user|
  ...
  user.save!
end
