Question

这刚刚开始发生，我不确定何时或是什么导致它，但出于某种原因设计是在保存时清除我的reset_password_token。

为了调试我的问题，我实施了

  def reset_password_token=(token)
    debugger
    self[:reset_password_token] = token
  end

在我的User对象上，以便我可以看到谁在设置它。

每当我执行user.save（）时，我的reset_password_token设置为nil，这里是callstack：

在设计中我看到了：

 if email_changed? || encrypted_password_changed?
        clear_reset_password_token
 end

如果是这样，我应该如何设置令牌并同时创建用户。我找到的工作是在保存之后设置令牌，这似乎有效，但不确定为什么这才刚开始发生..

Answer 1

我遇到了同样的问题。似乎唯一的解决方案是在设置reset_password_token

之前保存用户

user = User.new
user.email = 'test@example.com'
user.save # save
user.reset_password_token = 'token'
user.reset_password_sent_at = Time.now.utc
user.save # save again

Answer 2

刚刚处理了这个并来到这里寻求建议。经过一些调整和测试后，我的解决方案只是在对象上执行保存以清除_changed？登录。我在after_create中为用户执行此操作：

def email_credentials
    self.save
    self.send_reset_password_instructions
end

设计保存用户导致reset_password_token设置为nil
