Q: Rails 3.2.3 End user error messages instead of developer error messages in development mode with consider_all_requests_local = true I am running my rails 3.2.3 app in development mode.
Even though I have specified
config.consider_all_requests_local = true

in my config/environments/development.rb configuration file, I get the "end user friendly" error pages with the red "We're sorry, but something went wrong." when I have errors in my views, instead of the more useful "developer friendly" error pages with stack trace, etc.
What can I do to get the developer friendly error messages?
Among my gems are omniauth and slim
Edit:
The problem occurs when there are errors in views. When there are errors in controllers, the developer-friendly errors show correctly.

A: Have had exactly the same problem, described in the question in the bottom. Only saw this message in views, although development mode is and consider_all_requests_local is on. In addition, my file did not contain any illegal utf-8 characters (or was marked via encoding: utf-8).
But today, I finally found the solution for my problem - hope it helps you:
Rails doesnt log tempalte errors in development mode
