From 9734c9b6fe2d2e4a980d8ad94c5de0300b23c809 Mon Sep 17 00:00:00 2001 From: ThibG Date: Sun, 20 Dec 2020 18:05:03 +0100 Subject: [PATCH] Add clean error message when RAILS_ENV is unset (#15381) By default, an unset RAILS_ENV is understood as RAILS_ENV=development. However, this is not what most people expect, and due to development-only dependencies, users are often left with confusing error messages. This commit changes it so that an explicit RAILS_ENV is required, and failing that, an error message is displayed before loading the app. Co-authored-by: Claire --- config/boot.rb | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/config/boot.rb b/config/boot.rb index f3e36203a..6cde5319d 100644 --- a/config/boot.rb +++ b/config/boot.rb @@ -1,3 +1,8 @@ +unless ENV.key?('RAILS_ENV') + STDERR.puts 'ERROR: Missing RAILS_ENV environment variable, please set it to "production", "development", or "test".' + exit 1 +end + ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../Gemfile', __dir__) require 'bundler/setup' # Set up gems listed in the Gemfile.
