Question

我有问题。我试图使用控制台保存用户，但它无法正常工作，我无法确定问题所在。

这是日志：

2.0.0-p353 :095 >   u = User.find_by_email('xxxx@gmail.com')
 => #<User id: 5359, created_at: "2012-01-14 12:39:01", updated_at: "2014-07-04 09:48:06", email: "xxxx@gmail.com", encrypted_password: "xxxx.", role_id: nil, reset_password_token: "xxxx...", reset_password_sent_at: "2014-07-02 15:21:06", remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, confirmed_at: "2014-07-04 09:46:08", confirmation_sent_at: nil, confirmation_token: nil, unconfirmed_email: nil, failed_attempts: 0, unlock_token: nil, locked_at: nil, legacy_pass: "xxxxx", username: "Mr. Brightside", discourse_id: nil, my_draft_comments_count: 0, my_published_comments_count: 37, my_comments_count: 37, draft_comcoms_count: 0, published_comcoms_count: 0, deleted_comcoms_count: 0, spam_comcoms_count: 0, mailchimped: false, slug: "mr-brightside", accept_rules: true, accept_privacy: true>

有什么想法吗？

根据save!的{{3}}：

如果正在更新记录，则会以静默方式忽略标记为只读的属性。

所以检查是否是这种情况。否则它应该按预期工作。

此外，要从数据库中检查实际保存的记录，您可能需要在控制台中调用u.reload。您在最后一行检查的对象与原始时间戳具有相同的updated_at时间戳，因此要么根本没有更新，要么没有从DB重新加载（除非您快速键入reaaaaally）。

ActiveRecord不保存有效属性
