密码重置让我在生产中出现 500 错误

Question

我正尝试按照 Michael Hartl 的教程将密码重置添加到我的应用程序。在 localhost:3000 中，当我输入我的电子邮件以发送密码重置时，它说它有效（我得到一个 flash[:success]，因为它是按程序设置的）。然后当我访问邮件程序预览并重置我的密码时，它起作用了（虽然我实际上没有收到电子邮件，所以我不知道 reset_digest 是否真的被创建了，因为 user_mailer_preview 自动为数据库中的第一个用户（我）创建一个。

但是，在生产环境中（在 heroku 上），当我输入我的电子邮件以发送密码重置时，我只收到 500 错误。这是我的 heroku 日志：

这是我的控制器的一部分：

def create
    @user = User.find_by(email: params[:password_reset][:email].downcase)
    if @user
      @user.send_password_reset_email
        flash[:info] = "An email was sent to " + @user.email + " with password reset instructions."
        redirect_to login_url
    else
        flash.now[:danger] = "Hmm. We don't recognize that email. Make sure you signed up with this email."
        render 'new'
    end
  end

这是我的用户模型的一部分 create_reset_digest:

def create_reset_digest
    self.reset_token = User.new_token
    update_attribute(:reset_digest, User.digest(reset_token))
    update_attribute(:reset_sent_at, Time.zone.now)
  end

  def send_password_reset_email
    UserMailer.password_reset(self).deliver_now
  end

所以它告诉我没有 reset_digest 这样的方法，我很困惑，因为我从来没有真正调用过它。我在 def create 中调用 @user.create_reset_digest，我认为这是 heroku logs 调用的行。我该如何解决这个错误？

Answer 1

So it's telling me that there's no such method as reset_digest, which I'm confused because I never actually call that. I call @user.create_reset_digest in def create, and I think that's the line that heroku logs are calling out

没有！ @user.create_reset_digest 在你的 user.rb 中调用 create_reset_digest 实际上是 updating reset_digest第 update_attribute(:reset_digest, User.digest(reset_token))

行

NoMethodError (undefined method `reset_digest=' for User:0x007ff5bbb90f88

我相信你没有运行 migrations heroku 。您应该运行使用以下命令进行迁移。

heroku run rake db:migrate

这应该可以解决您的错误。
