ruby-on-rails - 在 rails 4 中显示语法错误

Question

如何在 rails 4 中显示 slim 语法错误。当我使用 rails 3 和 slim all slim 语法错误时，当我迁移到 rails 4 时，我在浏览器中看到了 slim 语法错误，仅在控制台中显示。在浏览器中，我只看到 http 500 错误和消息 We're sorry, but something went wrong .如何在浏览器中显示语法错误？

例如如何显示此错误而不是 http 错误 500:

Started GET "/tests" for 127.0.0.1 at 2014-01-09 14:44:55 +0400
Processing by TestsController#index as HTML
  Rendered tests/index.html.slim within layouts/application (2.2ms)
Completed 500 Internal Server Error in 5ms

ActionView::Template::Error (Text line not indented deep enough.
The first text line defines the necessary text indentation.
Are you trying to nest a child tag in a tag containing text? Use | for the text block!
  /Users/sergey-chechaev/rails/project/test_rails_4/app/views/tests/index.html.slim, Line 2, Column 1
    p = week_field_tag :week

Answer 1

在开发模式下，Slim 语法错误不会在浏览器中显示，因为目前正在讨论一个问题。引发异常时，Rails 4 和 Slim 似乎无法正常通信。
