From 48c0abb4748c30adeecc17058f0220e87bcbe84a Mon Sep 17 00:00:00 2001 From: Prem Sichanugrist Date: Wed, 26 Jun 2019 19:33:22 +0900 Subject: Fix problem with accessing constant proxy subclass This commit fixes #36313. After #32065 moved `SourceAnnotationExtractor` into `Rails` module, it broke the ability to access `SourceAnnotationExtractor::Annotate` directly as user would get this error: TypeError: Rails::SourceAnnotationExtractor is not a class/module This commit fixes the issue by making `DeprecatedConstantProxy` to inherit from `Module` and then defines `method_missing` and `const_missing` to retain the previous functionality. Thank you Matthew Draper for the idea of how to fix the issue!
