* For `PostgreSQL >= 9.4` use `gen_random_uuid()`Yaw Boakye2016-11-223-8/+21
| | | | | | | | | | 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.
* Introduce `reload_<association>` reader for singular associations.Yves Senn2016-11-222-1/+17
| | | | | | | | | | | | | | | | This patch brings back the functionality of passing true to the association proxy. The behavior was deprecated with #20888 and scheduled for removal in Rails 5.1. The deprecation mentioned that instead of `Article.category(true)` one should use `article#reload.category`. Unfortunately the alternative does not expose the same behavior as passing true to the reader did. Specifically reloading the parent record throws unsaved changes and other caches away. Passing true only affected the association. This is problematic and there is no easy workaround. I propose to bring back the old functionality by introducing this new reader method for singular associations.
* `eager_autoload` needs to be triggered for nested constants.Yves Senn2016-11-211-0/+5
| | | | | | | | | | | | | | | When `ActiveRecord::Associations.eager_load!` is called, it eager loads the `Preloader` but does not trigger a `eager_load!` on the `Preloader` itself. A eager loaded component is responsible to forward the `eager_load!` call to nested constants that make use of `eager_autoload` as well. This will also resolve the occasional `NameError` that we've observed in production: ``` NameError: uninitialized constant ActiveRecord::Associations::Preloader::BelongsTo ```

| * | Should except `:distinct` rather than `:order` for `exists?`Ryuta Kamizono2016-11-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Records fetching order is very important for performance if `limit` is presented. Should not except the order in the case. And `exists?` replaces select list to `1 AS one` therefore `:distinct` is useless (`DISTINCT 1 AS one`). And PostgreSQL raises the following error if `:distinct` and `:order` are used in the same time. ``` ERROR: for SELECT DISTINCT, ORDER BY expressions must appear in select list ```

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if `CollectionProxy` has more than one new record, `CollectionProxy#uniq` result is incorrect. And `CollectionProxy#uniq` was aliased to `distinct` in a1bb6c8b06db. But the `uniq` method and the `SELECT DISTINCT` method are different methods. The doc in `CollectionProxy` is for the `SELECT DISTINCT` method, not for the `uniq` method. Therefore, reverting the alias in `CollectionProxy` to fix the inconsistency and to have the both methods.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported via #26904, there is a regression in how values for Postgres' HStore column type are being processed, beginning in Rails 5. Currently, the way that Active Record checks whether or not values need to be serialized and put into the correct storage format is whether or not it is a `Hash` object. Since `ActionController::Parameters` no longer inherits from `Hash` in Rails 5, this conditional now returns false. To remedy this, we are now checking to see whether the `value` parameters being passed in responds to a certain method, and then calling the `serialize` method, except this time with a real Hash object. Keeping things DRY! Fixes #26904.

There were a handful of cases where we were relying on specific quirks in tests that had to be updated. The change to has_one associations was due to a particularly interesting test where an autosaved has_one association was replaced with a new child, where the child failed to save but the test wanted to check that the parent id persisted to `nil`. I think this is almost certainly the wrong behavior, and I may change that behavior later. But ultimately the root cause was because we never remove the parent in memory when nullifying the child. This makes #23197 no longer needed, but it is what we'll do to fix some issues on 5.0 Close #23197
* | | | Deprecate the behavior of AR::Dirty inside of after_(create|update|save) ↵Sean Griffin2016-11-0115-51/+276
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | callbacks We pretty frequently get bug reports that "dirty is broken inside of after callbacks". Intuitively they are correct. You'd expect `Model.after_save { puts changed? }; model.save` to do the same thing as `model.save; puts model.changed?`, but it does not. However, changing this goes much farther than just making the behavior more intuitive. There are a _ton_ of places inside of AR that can be drastically simplified with this change. Specifically, autosave associations, timestamps, touch, counter cache, and just about anything else in AR that works with callbacks have code to try to avoid "double save" bugs which we will be able to flat out remove with this change. We introduce two new sets of methods, both with names that are meant to be more explicit than dirty. The first set maintains the old behavior, and their names are meant to center that they are about changes that occurred during the save that just happened. They are equivalent to `previous_changes` when called outside of after callbacks, or once the deprecation cycle moves. The second set is the new behavior. Their names imply that they are talking about changes from the database representation. The fact that this is what we really care about became clear when looking at `BelongsTo.touch_record` when tests were failing. I'm unsure that this set of methods should be in the public API. Outside of after callbacks, they are equivalent to the existing methods on dirty. Dirty itself is not deprecated, nor are the methods inside of it. They will only emit the warning when called inside of after callbacks. The scope of this breakage is pretty large, but the migration path is simple. Given how much this can improve our codebase, and considering that it makes our API more intuitive, I think it's worth doing.
