我在Unicorn后面使用Rails 5。当我运行访问我的应用程序的生产实例上的特定页面时，我收到错误
We're sorry, but something went wrong.
If you are the application owner check the logs for more information.
当我查看myproject / log / production.log文件时，我看到了请求，但没有解释错误发生的原因......
Started GET "/my_objects/search?utf8=%E2%9C%93&first_name=Dave&last_name=&my_object=&x=12&y=13" for 96.84.106.123 at 2017-12-29 15:34:20 -0500
Processing by my_objectsController#search as HTML
Parameters: {"utf8"=>"✓", "first_name"=>"Dave", "last_name"=>"", "my_object"=>"", "x"=>"12", "y"=>"13"}
Rendering my_objects/search.html.erb within layouts/my_object
Rendered my_objects/_search.html.erb (1.3ms)
如何启用错误以显示在我的日志文件中？以下是我在./config/environments/production.rb文件中配置记录器的方法......
