From 5c73f0d398d2a7ed955040e580374e92d6536283 Mon Sep 17 00:00:00 2001 From: Brian McManus Date: Tue, 19 Feb 2013 17:51:23 -0800 Subject: Fix time_zone_options_for_select to not mutate TimeZones array Previous implementation of time_zone_options_for_select did not dup the ActiveSupport::TimeZone.all array. When :priority_zones were provided the method would reject! the zones from the memoized TimeZones array thus affecting future requests to the server. Essentially whatever zones were specified as :priority_zones would show up for the first request but then disappear from the time zone options on future requests. --- actionpack/CHANGELOG.md | 8 ++++++++ actionpack/lib/action_view/helpers/form_options_helper.rb | 2 +- actionpack/test/template/form_options_helper_test.rb | 7 +++++++ 3 files changed, 16 insertions(+), 1 deletion(-) diff --git a/actionpack/CHANGELOG.md b/actionpack/CHANGELOG.md index 6047c83167..9b8b175450 100644 --- a/actionpack/CHANGELOG.md +++ b/actionpack/CHANGELOG.md @@ -1,5 +1,13 @@ ## Rails 4.0.0 (unreleased) ## +* Fix `time_zone_options_for_select` to call `dup` on the returned TimeZone array. + + Previously if you supplied :priority_zones options to `time_zone_options_for_select` + the memoized ActiveSupport::TimeZone.all array would be mutated.
