From 3f95054f1c5ffe9e9b3bccdabc1ab1a7a4beb24a Mon Sep 17 00:00:00 2001 From: Andrew White Date: Sun, 11 Mar 2018 18:23:50 +0000 Subject: Normalize date component when writing to time columns For legacy reasons Rails stores time columns on sqlite as full timestamp strings. However because the date component wasn't being normalized this meant that when they were read back they were being prefixed with 2001-01-01 by ActiveModel::Type::Time. This had a twofold result - first it meant that the fast code path wasn't being used because the string was invalid and second it was corrupting the second fractional component being read by the Date._parse code path. Fix this by a combination of normalizing the timestamps on writing and also changing Active Model to be more lenient when detecting whether a string starts with a date component before creating the dummy time value for parsing. --- activemodel/lib/active_model/type/time.rb | 6 +----- .../lib/active_record/connection_adapters/sqlite3/quoting.rb | 2 +- activerecord/test/cases/adapters/sqlite3/quoting_test.rb | 7 +++++++ 3 files changed, 9 insertions(+), 6 deletions(-) diff --git a/activemodel/lib/active_model/type/time.rb b/activemodel/lib/active_model/type/time.rb index 8e939ac00a..c094ee0013 100644 --- a/activemodel/lib/active_model/type/time.rb +++ b/activemodel/lib/active_model/type/time.rb @@ -31,11 +31,7 @@ module ActiveModel return apply_seconds_precision(value) unless value.is_a?(::String) return if value.empty? - if value.start_with?("2000-01-01") - dummy_time_value = value - else - dummy_time_value = "2000-01-01 #{value}" - end + dummy_time_value = value.sub(/\A(\d\d\d\d-\d\d-\d\d |)/, "2000-01-01 ") fast_string_to_time(dummy_time_value) || begin time_hash = ::Date._parse(dummy_time_value) diff --git a/activerecord/lib/active_record/connection_adapters/sqlite3/quoting.rb b/activerecord/lib/active_record/connection_adapters/sqlite3/quoting.rb index 8042dbfea2..70de96326c 100644 --- a/activerecord/lib/active_record/connection_adapters/sqlite3/quoting.rb +++ b/activerecord/lib/active_record/connection_adapters/sqlite3/quoting.rb @@ -17,7 +17,7 @@ module ActiveRecord end def quoted_time(value) - quoted_date(value) + quoted_date(value).sub(/\A\d\d\d\d-\d\d-\d\d /, "2000-01-01 ") end def quoted_binary(value) diff --git a/activerecord/test/cases/adapters/sqlite3/quoting_test.rb b/activerecord/test/cases/adapters/sqlite3/quoting_test.rb index 6fdb353368..1c85ff5674 100644 --- a/activerecord/test/cases/adapters/sqlite3/quoting_test.rb +++ b/activerecord/test/cases/adapters/sqlite3/quoting_test.rb @@ -55,4 +55,11 @@ class SQLite3QuotingTest < ActiveRecord::SQLite3TestCase assert_equal "'2000-01-01 12:30:00.999999'", @conn.quote(type.serialize(value)) end + + def test_quoted_time_normalizes_date_qualified_time + value = ::Time.utc(2018, 3, 11, 12, 30, 0, 999999) + type = ActiveRecord::Type::Time.new + + assert_equal "'2000-01-01 12:30:00.999999'", @conn.quote(type.serialize(value)) + end end -- cgit v1.2.3
