From a930f5ba0654e8c8c7ac7b3febbb573d03559a40 Mon Sep 17 00:00:00 2001 From: Keenan Brock Date: Mon, 7 Jan 2019 14:13:45 -0500 Subject: Fix safe_constantize to not raise a LoadError. ### Summary There was an issues when using `safe_constantize` on a string that has the wrong case. File `em.rb` defines `EM`. `"Em".safe_constantize` causes a little confusion with the autoloader. The autoloader finds file "em.rb", expecting it to define `Em`, but `Em` is not defined. The autoloader raises a `LoadError`, which is good, But `safe_constantize` is defined to return `nil` when a class is not found. ### Before ``` "Em".safe_constantize LoadError: Unable to autoload constant Em, \ expected rails/activesupport/test/autoloading_fixtures/em.rb to define it ``` ### After ``` "Em".safe_constantize # => nil ``` --- activesupport/lib/active_support/inflector/methods.rb | 2 ++ 1 file changed, 2 insertions(+) (limited to 'activesupport/lib') diff --git a/activesupport/lib/active_support/inflector/methods.rb b/activesupport/lib/active_support/inflector/methods.rb index 1af9833d46..ee193add6f 100644 --- a/activesupport/lib/active_support/inflector/methods.rb +++ b/activesupport/lib/active_support/inflector/methods.rb @@ -328,6 +328,8 @@ module ActiveSupport e.name.to_s == camel_cased_word.to_s) rescue ArgumentError => e raise unless /not missing constant #{const_regexp(camel_cased_word)}!$/.match?(e.message) + rescue LoadError => e + raise unless /Unable to autoload constant #{const_regexp(camel_cased_word)}/.match?(e.message) end # Returns the suffix that should be added to a number to denote the position -- cgit v1.2.3
