Rails: Turn off error display

问题

When I access a post that doesn't exist in my Rails project via the URL /posts/13, the browser shows a verbose error:

ActiveRecord::RecordNotFound in PostsController#show

Couldn't find Post with ID=13
Rails.root: ...
...
Request

Parameters:

{"id"=>"13"}
...

Is there a way to turn this detailed error display off?

回答1:

Try this:

• run a server in production $ rails s -e production

• remove ActionDispatch::DebugExceptions middleware

  config.middleware.delete(ActionDispatch::DebugExceptions)

• set config.consider_all_requests_local = false in your environment config
