Rails 完整错误页面未显示视图错误 [英] Rails full error page not showing for view errors

问题描述

我有一个名为 new.html.erb 的视图，代码如下:

I have a view named new.html.erb with the following code:

<%= some_non_existent_thing.imaginary_method %>

现在，我只看到一个简单的 500 错误页面，如下所示:

Now, I only see one simple 500 error page, like that:

500 内部服务器错误
如果您是此网站的管理员，请阅读此 Web 应用程序的日志文件和/或 Web 服务器的日志文件以找出问题所在.

500 Internal Server Error
If you are the administrator of this website, then please read this web application's log file and/or the web server's log file to find out what went wrong.

我不应该看到一个格式漂亮的页面，其中包含一些有关异常的信息吗?

Shouldn't I see a pretty formatted page with some information about the exception?

我不确定我在这里错过了什么，但我相信 Rails 曾经在视图中出现错误时在开发环境中显示完整的错误页面.

I'm not sure I miss something here, but I believe rails used to show the full error page in development environment when there is something wrong in the view.

推荐答案

您确定您正在运行开发环境吗?检查 RAILS_ENV=development 或您是否正在运行 rails server -e development.

Are you sure that you are running the development environment? Check that RAILS_ENV=development or that you are running rails server -e development.

然后检查您的 development.rb 文件，您应该在其中包含以下行

Then check your development.rb file, you should have the following line in it

config.consider_all_requests_local = true
