Question

我的应用程序在本地运行正常，但是当我推送到Heroku时，在Firefox中它说“页面没有正确重定向”（即302错误）。

运行heroku logs会产生一系列请求，如下所示：

2015-06-02T21:30:26.556750+00:00 heroku[router]: at=info method=GET path="/" host=www.mydomainname.com request_id=a0cb3aa2-af7c-431a-9cc4-a237e551ae0a fwd="173.27.229.45" dyno=web.1 connect=2ms service=13ms status=302 bytes=499
2015-06-02T21:30:27.761039+00:00 heroku[router]: at=info method=GET path="/" host=www.mydomainname.com request_id=32026d7d-2167-4058-8ef6-8ebd15af7460 fwd="173.27.229.45" dyno=web.1 connect=2ms service=12ms status=302 bytes=499
2015-06-02T21:30:27.914344+00:00 heroku[router]: at=info method=GET path="/" host=www.mydomainname.com request_id=2087a90c-fd56-4d14-b630-9c92fda30c80 fwd="173.27.229.45" dyno=web.1 connect=1ms service=15ms status=302 bytes=499

当我在Firefox的开发人员部分下运行“网络”选项时，它会不断显示它在包含和不包含www的域之间交替显示。例如：

www.domain.com
domain.com
www.domain.com
domain.com

等

我正在使用自定义域名，但是确切地设置了我的其他正在运行的应用程序的设置，所以我不会认为这是一个DNS问题，就如何设置去。此外，当我访问“myappname.herokuapp.com”网址时，由于某种原因，它会立即重定向到heroku.com。不知道为什么。我运行了“生产检查”，它通过了“DNS配置”部分。

我意识到我在这里没有提供一堆信息（不知道还有什么可以提供），但是关于我接下来会看到什么的任何想法？

编辑：今天是在之前发布的重定向代码之前说的：

编辑2：我将存储库重新克隆到另一个目录中，然后运行heroku create，git push heroku master，然后heroku run rake db:migrate。我这样做是为了消除任何可能的DNS问题。日志现在说：

2015-06-03T15:55:51.082260+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=lit-inlet-1933.herokuapp.com request_id=2cd494b9-8f93-4270-b8db-e1dda9a6ab4a fwd="173.27.229.45" dyno= connect= service= status=503 bytes=

这表示在根网址“/”上发生2次崩溃，在/favicon.ico上发生2次崩溃。基于favicon.ico，我从根页面删除了任何favicons作为测试。现在该应用程序的行为与前一个类似：它立即重定向到heroku.com而不是加载页面，日志说：

根URL非常简单。有一个welcome_controller：

class WelcomeController < ApplicationController
  skip_before_filter :authenticate_user!, only: :index

  def index    
  end
end

，视图是：

  <div class="jumbotron">
    <h1> Task Clash</h1>
    <p>A ridiculously simple and easy-to-use CRM/Time Tracking tool aimed at small businesses!</p>
    <p><%= link_to "Create Account", new_account_path, class: "btn btn-primary btn-lg" %></p>
  </div>

非常感谢任何帮助！

编辑3 ：我在我的Gemfile中添加了rails_12factor，现在得到了这个：

Answer 1

检查是否有待生产的迁移。从终端运行此命令： $ heroku run rake db:migrate

如果没有待处理的迁移，请发布更多日志行。

使用Heroku和Rails 4 App重定向循环
