While the majority of errors are received in development, they do occasionally occur in production, too. To ensure your users don't receive the debug information, you need to set consider_all_requests_local to false. In this video, you'll learn how to do this, as well as how to manage errors in production when working in Ruby on Rails 4.
…In this movie, I just want to talk briefly about…how you should handle errors in your production environment.…So far we've mostly been talking about what to do about errors in…your development environment, which is where…hopefully you'll get most of your errors.…But sometimes errors do happen in production as well.…And we want to make sure we handle those in the best way possible.…So, the first thing you want to do, is you want to make sure that…in your environment for production, the consider…all requests local is set to false.…We saw this before, we saw that for…the development environment, it's always set to true.…
What this does is it shows us the error in the browser.…So, it gives us all of that debug…information right there on the screen in the browser.…But in production we don't want to do that.…We don't want our users to get…all that valuable information about our application.…We want to keep that concealed.…So instead we are going to want to show…error pages that are custom tailored for them.…And those error pages just might simply say something went wrong.…
