* Enable `Layout/EmptyLinesAroundAccessModifier` copRyuta Kamizono2019-06-131-1/+0
| | | | | | | | | | | We sometimes say "✂️ newline after `private`" in a code review (e.g. https://github.com/rails/rails/pull/18546#discussion_r23188776, https://github.com/rails/rails/pull/34832#discussion_r244847195). Now `Layout/EmptyLinesAroundAccessModifier` cop have new enforced style `EnforcedStyle: only_before` (https://github.com/rubocop-hq/rubocop/pull/7059). That cop and enforced style will reduce the our code review cost.
* Fix dirty tracking for `touch`Ryuta Kamizono2019-04-151-1/+10
| | | | | | | | | | Before this fix, `touch` only clears dirty tracking for touched attributes, doesn't track saved (touched) changes. This fixes that tracks saved changes and carry over remaining changes. Fixes #33429. Closes #34306.
* Fix `touch` option to behave consistently with `Persistence#touch` methodRyuta Kamizono2018-06-181-9/+15
| | | | | | | | | | | | | | | | `touch` option was added to `increment!` (#27660) and `update_counters` (#26995). But that option behaves inconsistently with `Persistence#touch` method. If `touch` option is passed attribute names, it won't update update_at/on attributes unlike `Persistence#touch` method. Due to changed from `Persistence#touch` to `increment!` with `touch` option, #31405 has a regression that `counter_cache` with `touch` option which is passed attribute names won't update update_at/on attributes. I think that the inconsistency is not intended. To get back consistency, ensure that `touch` option updates update_at/on attributes.

* `id_in_database` should be respected as primary key value for persisted recordsRyuta Kamizono2018-03-051-0/+39
| | | | | | | | | | | | Currently primary key value can not be updated if a record has a locking column because of `_update_record` in `Locking::Optimistic` doesn't respect `id_in_database` as primary key value unlike in `Persistence`. And also, if a record has dirty primary key value, it may destroy any other record by the lock version of dirty record itself. When updating/destroying persisted records, it should identify themselves by `id_in_database`, not by dirty primary key value.

* Fix the test that was broken by #16445 rather than deleting itSean Griffin2015-07-191-0/+12
| | | | | | | | Since the counter cache was properly being updated, the model became stale. Simply reloading the model before attempting to destroy is sufficient for this case. I believe this is enough of an edge case to be a valid change to the tests, even though it represents a potential breaking change.
* Fix counter_cache for polymorphic associationsStefan Kanev2015-07-191-12/+0
| | | | | | | | | | | | | | Also removes a false positive test that depends on the fixed bug: At this time, counter_cache does not work with polymorphic relationships (which is a bug). The test was added to make sure that no StaleObjectError is raised when the car is destroyed. No such error is currently raised because the lock version is not incremented by appending a wheel to the car. Furthermore, `assert_difference` succeeds because `car.wheels.count` does not check the counter cache, but the collection size. The test will fail if it is replaced with `car.wheels_count || 0`.

* Closes rails/rails#18864: Renaming transactional fixtures to transactional testsBrandon Weiss2015-03-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | I’m renaming all instances of `use_transcational_fixtures` to `use_transactional_tests` and “transactional fixtures” to “transactional tests”. I’m deprecating `use_transactional_fixtures=`. So anyone who is explicitly setting this will get a warning telling them to use `use_transactional_tests=` instead. I’m maintaining backwards compatibility—both forms will work. `use_transactional_tests` will check to see if `use_transactional_fixtures` is set and use that, otherwise it will use itself. But because `use_transactional_tests` is a class attribute (created with `class_attribute`) this requires a little bit of hoop jumping. The writer method that `class_attribute` generates defines a new reader method that return the value being set. Which means we can’t set the default of `true` using `use_transactional_tests=` as was done previously because that won’t take into account anyone using `use_transactional_fixtures`. Instead I defined the reader method manually and it checks `use_transactional_fixtures`. If it was set then it should be used, otherwise it should return the default, which is `true`. If someone uses `use_transactional_tests=` then it will overwrite the backwards-compatible method with whatever they set.
* Properly persist `lock_version` as 0 if the DB has no defaultSean Griffin2015-01-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | The reason this bug occured is that we never actually check to see if this column has changed from it's default, since it was never assigned and is not mutable. It appears I was wrong in b301c40224c6d15b539dbcc7485adb44d810f88c, with my statement of "there is no longer a case where a given value would differ from the default, but would not already be marked as changed." However, I chose not to revert the deletion of `initialize_internals_callback` from that commit, as I think a solution closer to where the problem lies is less likely to get erroneously removed. I'm not super happy with this solution, but it mirrors what is being done in `_update_record`, and a fix for one should work for the other. I toyed with the idea of changing the definition of `changed?` on the type to `changed_in_place?`. If we type cast the raw value, it'll break a test about updating not modifying the lock column if nothing else was changed. We could have the definition check if `raw_old_value` is `nil`, but this feels fragile and less intention revealing. It would, however, have the benefit of cleaning up old data that incorrectly persisted as `nil`. Fixes #18422

* Specified column type for quote_valueAlfred Wong2013-07-221-0/+13
| | | | | | | | | | | | | | | | | | | | | When calling quote_value the underlying connection sometimes requires more information about the column to properly return the correct quoted value. I ran into this issue when using optimistic locking in JRuby and the activerecord-jdbcmssql-adapter. In SQLSever 2000, we aren't allowed to insert a integer into a NVARCHAR column type so we need to format it as N'3' if we want to insert into the NVARCHAR type. Unfortuantely, without the column type being passed the connection adapter cannot properly return the correct quote value because it doesn't know to return N'3' or '3'. This patch is fairly straight forward where it just passes in the column type into the quote_value, as it already has the ability to take in the column, so it can properly handle at the connection level. I've added the tests required to make sure that the quote_value method is being passed the column type so that the underlying connection can determine how to quote the value.
