保存用户模型时，我收到（验证失败：Uid 不能为空）。 Uid 本身属于 Identity 对象 - 它充当多个身份类型的单个身份访问点。换句话说，您将能够在应用程序中使用 facebook、twitter 或 linkedinomniauth 策略，而无需创建多个帐户。它似乎并不像广告中那样起作用。鉴于我从应用程序登录 LinkedIn 后无法创建用户。
我尝试将 env 引用替换为 request.env。因为，它不存在于当前的范围内。我尝试找到错误，但无法准确找到身份模型在创建用户之前不存储身份的原因。它在创建用户对象后立即失败，而不是检查用户是否存在并附加身份或是否应该创建。

预期行为：用户将成功登录其 Linkedin 帐户并被重定向到应用程序以完成注册。
实际结果：用户对象创建，然后保存Identity失败，Uid留空。
该错误是验证错误，UID 为空，这就是问题所在。看来您已经在数据库中保留了一条 UID 为零的用户记录。您的验证不允许您添加其他 UID 为零的用户。因此，您的 UID 无法正确通过，因此您的验证将失败。 – 拉科斯特尼编码器 2019 年 8 月 4 日 5:29
