Question

我正在跟踪使用Rails的Agile Web开发（rails 3.2+），我在第16章，关于部署。但是，我正在跳过大部分b / c我正在计划使用Heroku，我正在试图解决这个问题。无论如何，我昨天成功解密了我的应用程序并且它工作正常，除了我的一个模型。我的'订单'模式总是返回“我们很抱歉，但出了点问题。”错误，我无法弄清楚为什么。这是'heroku logs'

如您所见，存在500内部服务器错误。但是，我不知道是什么原因引起的。我所有的其他型号都运行得很好。这不像是我添加了“订单”模型并且忘记了迁移。我知道'orders'表正在运行，因为我安装了一个sql控制台，我可以看到所有记录的条目。此外，它在当地工作得很好。我也这样做是为了看到更多错误报告：

config.consider_all_requests_local       = true

但是，我没有得到比'heroku logs'更多的信息。任何和所有输入将不胜感激。

订单控制器代码：

class OrdersController < ApplicationController
    skip_before_filter :authorize, only: [:new, :create]

  # GET /orders
  # GET /orders.json
  def index
    @orders = Order.paginate page: params[:page], order: 'created_at desc',
      per_page: 10

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @orders }
    end

Answer 1

我认为问题在于您的邮件程序，请尝试使用sendgrid

devcenter.heroku.com/articles/sendgrid#usage

Answer 2

我在您的错误日志中注意到您正在发送电子邮件，这可能会导致问题。 Heroku不会为您发送电子邮件，因此您需要使用Gmail或获取附加组件。

Heroku电子邮件参考：https://devcenter.heroku.com/articles/smtp
