From de9e3238a008f8f20c5beedefb8787b6e51359d0 Mon Sep 17 00:00:00 2001 From: "yuuji.yaginuma" Date: Wed, 27 Sep 2017 13:18:34 +0900 Subject: Ensure `HashWithIndifferentAccess#transform_keys` to return `HashWithIndifferentAccess` Currently, `#transform_values`, `#select` and `#reject` return instance of `HashWithIndifferentAccess`. But `#transform_keys` returns instance of Hash. This behavior is a bit confusing. I think that `HashWithIndifferentAccess#transform_keys` should also return instance of `HashWithIndifferentAccess` as well as other methods. --- activesupport/lib/active_support/hash_with_indifferent_access.rb | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'activesupport/lib') diff --git a/activesupport/lib/active_support/hash_with_indifferent_access.rb b/activesupport/lib/active_support/hash_with_indifferent_access.rb index 12291af443..fcc13feb8c 100644 --- a/activesupport/lib/active_support/hash_with_indifferent_access.rb +++ b/activesupport/lib/active_support/hash_with_indifferent_access.rb @@ -306,6 +306,11 @@ module ActiveSupport dup.tap { |hash| hash.transform_values!(*args, &block) } end + def transform_keys(*args, &block) + return to_enum(:transform_keys) unless block_given? + dup.tap { |hash| hash.transform_keys!(*args, &block) } + end + def compact dup.tap(&:compact!) end -- cgit v1.2.3
