Ruby on rails 调试Heroku错误日志

刚刚尝试通过heroku部署我的第一个应用程序。一切都已连接，但由于某种原因，应用程序将不会显示，保留默认应用程序。我已经安装了日志，但它们跟踪的错误出现在我甚至没有访问过的页面上（或者知道如何访问）。我能在这个块中更改的唯一错误是应用程序页面上的语法错误

我认为问题在于您的一个控制器/模型的类名没有正确大写

检查您的型号/控制器是否具有正确的资本化，例如

class YourController < ApplicationController
end

更新第二号： 添加到

config/Application.rb

：

require 'rails/all'
require "active_record/railtie"

或者说：

config.active_record.raise_in_transactional_callbacks = true

谢谢回复，但我的应用程序在下面，没有我的应用程序的名称。它还会出错吗？
