From 505526335b1be76c74068d5d0735d175dd9e4193 Mon Sep 17 00:00:00 2001 From: Ryuta Kamizono Date: Sun, 11 Oct 2015 21:45:55 +0900 Subject: Correctly dump native timestamp types for MySQL The native timestamp type in MySQL is different from datetime type. Internal representation of the timestamp type is UNIX time, This means that timestamp columns are affected by time zone. ``` > SET time_zone = '+00:00'; Query OK, 0 rows affected (0.00 sec) > INSERT INTO time_with_zone(ts,dt) VALUES (NOW(),NOW()); Query OK, 1 row affected (0.02 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 22:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) > SET time_zone = '-08:00'; Query OK, 0 rows affected (0.00 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 14:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) ``` --- activerecord/test/cases/primary_keys_test.rb | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'activerecord/test/cases/primary_keys_test.rb') diff --git a/activerecord/test/cases/primary_keys_test.rb b/activerecord/test/cases/primary_keys_test.rb index 03c8644229..12386635f6 100644 --- a/activerecord/test/cases/primary_keys_test.rb +++ b/activerecord/test/cases/primary_keys_test.rb @@ -291,6 +291,14 @@ class PrimaryKeyAnyTypeTest < ActiveRecord::TestCase schema = dump_table_schema "barcodes" assert_match %r{create_table "barcodes", primary_key: "code", id: :string, limit: 42}, schema end + + if current_adapter?(:Mysql2Adapter) && subsecond_precision_supported? + test "schema typed primary key column" do + @connection.create_table(:scheduled_logs, id: :timestamp, precision: 6, force: true) + schema = dump_table_schema("scheduled_logs") + assert_match %r/create_table "scheduled_logs", id: :timestamp, precision: 6/, schema + end + end end class CompositePrimaryKeyTest < ActiveRecord::TestCase -- cgit v1.2.3
