Question

首先，我是Ruby on Rails的新手，如果这个问题看起来很蠢，那就很抱歉。

我正在关注Heroku for Rails应用程序的教程，当我运行git push heroku master并去查看实际网站时，我收到以下消息：我们很抱歉，但出了点问题。如果您是应用程序所有者，请检查日志以获取更多信息。

当我在控制台中运行heroku日志时，我得到以下内容：

考虑到这一点，我找不到任何可能导致问题的原因。

到目前为止，这是我的database.yml文件的样子：

development:
 adapter: postgresql
 database: tscope_dev
 pool: 5
 timeout: 5000

test:
 adapter: postgresql
 database: tscope_test
 pool: 5
 timeout: 5000

production:
 adapter: postgresql
 database: tscope_production
 pool: 5
 timeout: 5000

我的宝石文件：

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

我创建了数据库并进行了迁移，并且还运行了bundle install。它是最基本的应用程序，只有一个控制器使用脚手架生成。

有人知道可能出现什么问题吗？即使是最小的小费也会对我有所帮助，因为我现在还不知道该怎么看。

如果您需要有关我的代码的更多信息，请随时提问。

提前致谢：）

修改通过在控制台中运行heroku run rake db:migrate解决了此问题。原来我没有在Heroku上进行迁移。

Answer 1

这一行：

; ...etc...

%struct.Foo = type { i32, i32 }

declare %struct.Foo* @something_with_foo(%struct.Foo*)

; ...etc...

表示您尚未在heroku上运行迁移。

为此，请在您的控制台中执行：

ActionView::Template::Error (PG::UndefinedTable: ERROR:  relation "keywords" does not exist

无法在Heroku上部署基本的Rails应用程序
