Heroku 路线不起作用答案

【问题标题】：Heroku routes not workingHeroku 路线不起作用
【发布时间】：2012-08-29 22:28:53
【问题描述】：

所以我的主要 Rails 模型是“公司”。当我在本地托管我的应用程序并导航到 localhost:3000/companies 时，一切正常。但是当我导航到我的应用程序的 heroku 版本时：

http://calm-journey-2877.herokuapp.com/companies

.. 我收到错误“我们很抱歉，但出了点问题”

这表明该页面存在但正在产生某种错误。知道会发生什么吗？这是我通过阅读 Rails 教程书构建的一个非常基本的应用程序。

谢谢！！

这是 Heroku 日志。

【问题讨论】：

查看 Heroku 上的错误日志，看看出了什么问题，即heroku logs。这可能会为您指明正确的方向。它可能与路由无关，例如您可能忘记了构建和迁移数据库。

标签： ruby-on-rails heroku routes

【解决方案1】：

您是否在 Heroku heroku run rake db:migrate 中迁移了数据库？

【讨论】：

谢谢！这似乎有点帮助。但是，它并没有迁移所有内容.. 无论如何迁移我的所有六个迁移？抱歉，如果这是一个愚蠢的问题，我对 Rails 真的很陌生。
你怎么知道它没有运行你所有的迁移？
好的，我想我知道发生了什么。我使用 rake 任务直接从 CSV 文件将数据导入数据库。由于此任务将数据直接导入数据库，因此未创建迁移文件。我只需要以某种方式从 rake 任务中创建一个迁移文件。
你可以运行heroku run rake 'the_task_that_uses_the_csv_file'

【解决方案2】：

您的解决方案在 git 中。编写您的 rake 任务并确保它在您的 git 存储库中。

不如试试 Heroku 运行 rake your_task

将您的数据库种子文件用于其预期目的。
