* Add regression test against habtm memoized singular_idsAlberto Almagro2018-10-161-0/+12
| | | | | | | | | | | | | | | Starting in Rails 5.0.0 and still present in Rails 5.2.1, `singular_ids` got memoized and didn't reload after more items were added to the relation. Although 19c8071 happens to fix the issue, it only adds tests for `has_many` relations while this bug only affected `has_and_belongs_to_many` relations. This commit adds a regression test to ensure it never happens again with `habtm` relations. Ensures #34179 never gets reproduced.

* Ensure to test that `project.developers` is ordered by `developers.name desc`Ryuta Kamizono2018-10-151-1/+1
| | | | | | | | | `developers.name desc` was added at d59f3a7, but any test case isn't failed even if the `developers.name desc` is removed since all tested developers are consistently ordered on both `name` and `id`. I changed one developers creation ordering to ensure to test that `project.developers` is ordered by `developers.name desc`.
* Improve model attribute accessor method names for backtracesDylan Thacker-Smith2018-10-123-53/+21
| | | | | | | | Ruby uses the original method name, so will show the __temp__ method name in the backtrace. However, in the common case the method name is compatible with the `def` keyword, so we can avoid the __temp__ method name in that case to improve the name shown in backtraces or TracePoint#method_id.
* Basic API for connection switchingEileen Uchitelle2018-10-104-1/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR adds the ability to 1) connect to multiple databases in a model, and 2) switch between those connections using a block. To connect a model to a set of databases for writing and reading use the following API. This API supercedes `establish_connection`. The `writing` and `reading` keys represent handler / role names and `animals` and `animals_replica` represents the database key to look up the configuration hash from. ``` class AnimalsBase < ApplicationRecord connects_to database: { writing: :animals, reading: :animals_replica } end ``` Inside the application - outside the model declaration - we can switch connections with a block call to `connected_to`. If we want to connect to a db that isn't default (ie readonly_slow) we can connect like this: Outside the model we may want to connect to a new database (one that is not in the default writing/reading set) - for example a slow replica for making slow queries. To do this we have the `connected_to` method that takes a `database` hash that matches the signature of `connects_to`. The `connected_to` method also takes a block. ``` AcitveRecord::Base.connected_to(database: { slow_readonly: :primary_replica_slow }) do ModelInPrimary.do_something_thats_slow end ``` For models that are already loaded and connections that are already connected, `connected_to` doesn't need to pass in a `database` because you may want to run queries against multiple databases using a specific role/handler. In this case `connected_to` can take a `role` and use that to swap on the connection passed. This simplies queries - and matches how we do it in GitHub. Once you're connected to the database you don't need to re-connect, we assume the connection is in the pool and simply pass the handler we'd like to swap on. ``` ActiveRecord::Base.connected_to(role: :reading) do Dog.read_something_from_dog ModelInPrimary.do_something_from_model_in_primary end ```

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The delegation methods to named scope are defined when `method_missing` is invoked on the relation. Since #29301, the receiver in the named scope is changed to the relation like others (e.g. `default_scope`, etc) for consistency. Most named scopes would be delegated from relation by `method_missing`, since we don't allow scopes to be defined which conflict with instance methods on `Relation` (#31179). But if a named scope is defined with the same name as any method on the `superclass` (e.g. `Kernel.open`), the `method_missing` on the relation is not invoked. To address the issue, make the delegation methods to named scope is generated in the definition time. Fixes #34098.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since #31575, `set_inverse_instance` replaces the foreign key by the current owner immediately to make it happen when a record is added to collection association. But `set_inverse_instance` is not only called when a record is added, but also when a record is loaded from queries. And also, that loaded records are not always associated records for some reason (using `or`, `unscope`, `rewhere`, etc). It is hard to distinguish whether or not we should invoke `set_inverse_instance`, but at least we should avoid the undesired side-effect which was brought from #31575. Fixes #34108.

Currently, if remove `to_s` added in #33968 from `env_name.to_s` on the line (activerecord/lib/active_record/database_configurations.rb:107), there is no test that would fail.

| | | | | | | | | | | | | | | | | | `test_update_does_not_run_sql_if_record_has_not_changed` would pass without #18501 since `assert_queries` ignores BEGIN/COMMIT unless `ignore_none: true` is given. Since #32647, empty BEGIN/COMMIT is ommited. So we no longer need to use `assert_queries(0)` to ignore BEGIN/COMMIT in the queries.
