* Fix conflicts `counter_cache` with `touch: true` by optimistic locking.bogdanvlviv2017-12-121-1/+2

| | | | | | | Since 5c71000, it has lost to be able to unscope `default_scope` in STI associations. This change will use `.empty_scope?` instead of `.values.empty?` to regard as an empty scope if only have `type_condition`.

* Fix ActiveRecord::Persistence#touch with lockingbogdanvlviv2017-06-211-0/+2
| | | | | | `ActiveRecord::Persistence#touch` does not work well when optimistic locking enabled and `locking_column`, without default value, is null in the database.
* Use nullable `id` column instead of a primary keyRyuta Kamizono2017-06-161-1/+2
| | | | | | | | | `id` column in `subscribers` was added as a primary key for ignorable in INSERT. But it caused `NotNullViolation` for oracle-enhanced adapter. https://github.com/rsim/oracle-enhanced/issues/1357 I changed the column to nullable to address the issue.
* Avoid overwriting the methods of `AttributeMethods::PrimaryKey`Ryuta Kamizono2017-06-071-6/+8
| | | | | | | | | Currently the methods of `AttributeMethods::PrimaryKey` are overwritten by `define_attribute_methods`. It will be broken if a table that customized primary key has non primary key id column. It should not be overwritten if a table has any primary key. Fixes #29350.
* Don't attempt to create a new record that was already created.Isaac Betesh2017-04-201-0/+7
| | | | Fixes #24032
* Use a query that's compatible with PostgreSQL 9.2Matthew Draper2017-04-121-3/+5
| | | | | | Also, explicitly apply the order: generate_subscripts is unlikely to start returning values out of order, but we should still be clear about what we want.
* Correctly dump native timestamp types for MySQLRyuta Kamizono2017-02-231-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) ```

| | | | | | | | Follow up to #26266. The default type of `primary_key` and `references` were changed to `bigint` since #26266. But legacy migration and sqlite3 adapter should keep its previous behavior.

* For `PostgreSQL >= 9.4` use `gen_random_uuid()`Yaw Boakye2016-11-221-0/+1
| | | | | | | | | | Since 9.4, PostgreSQL recommends using `pgcrypto`'s `gen_random_uuid()` to generate version 4 UUIDs instead of the functions in the `uuid-ossp` extension. These changes uses the appropriate UUID function depending on the underlying PostgreSQL server's version, while maintaining `uuid_generate_v4()` in older migrations.
