Question

我正在尝试按照Michael Hartl的教程添加密码重置到我的应用程序。在localhost：3000中，当我输入我的电子邮件以发送密码重置时，它表示它可以正常工作（我得到一个闪存[：成功]，因为它已经编程完成）。然后当我访问邮件程序预览并重置我的密码时，它可以工作（虽然我实际上并没有收到电子邮件，所以我不知道是否真的创建了reset_digest，因为user_mailer_preview会自动创建一个对于数据库中的第一个用户（我）。

然而，在生产中（在heroku上），当我输入我的电子邮件发送密码重置时，我只得到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create_reset_digest：

的一部分

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称之为。我在@user.create_reset_digest中致电def create，我认为这是heroku logs正在呼唤的行。我该如何解决这个错误？

所以它告诉我，没有像reset_digest这样的方法我很困惑，因为我从来没有真正称呼它。我打电话 def create中的@ user.create_reset_digest，我认为这就是行 heroku日志正在呼唤

没有！ create_reset_digest在user.rb中调用reset_digest中的update_attribute(:reset_digest, User.digest(reset_token))实际上更新 heroku run rake db:migrate此行File f = new File("Audio/Testing/mbgitr.wav"); try { ProcessBuilder pb = new ProcessBuilder("bash/extractAudio.sh", f.getAbsolutePath()); pb.inheritIO(); pb.start(); }catch(IOException e){ System.out.println("Oh no!"); } System.out.println(new File("Audio/mbgitr.wav").exists());

我认为您没有在 heroku 上运行迁移。您应该使用以下命令运行迁移。

/home/Ryan/Development/Java/Test/Audio/Testing/mbgitr.wav
mbgitr.wav
/home/Ryan/Development/Java/Test
false
ffmpeg version 2.6.2 Copyright (c) 2000-2015 the FFmpeg developers

Process finished with exit code 0

这可以解决您的错误。
