* Extract `integer_like_primary_key_type` to ease to handle it for adaptersRyuta Kamizono2017-09-254-17/+18

* Move integer-like primary key normalization to `new_column_definition`Ryuta Kamizono2017-09-236-38/+28
| | | | | | Currently the normalization only exists in `primary_key` shorthand. It should be moved to `new_column_definition` to also affect to `add_column` with primary key.
* Adding legacy primary key should be compatibleRyuta Kamizono2017-09-232-0/+70
| | | | | | | Currently implicit legacy primary key is compatible, but adding explicit legacy primary key is not compatible. It should also be fixed. Fixes #30664.

| | | | | | | `change_column_{default,null,comment}` in mysql2 adapter are passing `column.sql_type` as `type` to `change_column` to intend keeping previous type. But `column_for` requires extra query, so use passing `nil` to `type` explicitly in the internal for the purpose.

| | | | | | | | | | | | | | | | | | | | | | | | Since we have `Preloader#preload`, `Preloader::Association#preload` is a little confusing. And also, since the `preload` method is an abstract method, it is hard to read where `associated_records_by_owner` is called. This refactors `Preloader::Association` to ease to read where `associated_records_by_owner` is called.

| | | | | | | | | | | | | | | | | | | | | Class level `update` and `destroy` are using `find` in the internal, so it will raise `RecordNotFound` if given ids cannot find an object even though the method already affect (update or destroy) to any objects. These methods should return affected objects even in that case.
* | | Place class level `update`, `destroy`, and `delete` in ↵Ryuta Kamizono2017-09-183-95/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `Persistence::ClassMethods` The docs are obviously for class level `update`, `destroy`, and `delete`. It should be placed in `Persistence::ClassMethods` rather than `Relation`. And also, these methods are not dependent on relation. So it is not needed to delegate to `all` (plus, `klass.find` is faster than `relation.find`).

And also, comparing relations is a little expensive (will cause `build_arel`). It is enough to use `empty_scope?` to determine whether empty scope.
* | | Remove useless condition in `reset_association`Ryuta Kamizono2017-09-181-2/+1

* | | Fix docs describing rollback [ci skip]dixpac2017-09-171-2/+2
| |/ |/| | | | | | | | | | | * `rails db:migrate STEP = 2` will not rollback the migrations, instead `rails db:rollback STEP = 2` will do the rollback. * Also, rewritten `rails db:migrate VERSION` => `rails db:rollback VERSION` for consistency.
* | Remove unused explicit delegation to `klass` in `relation`Ryuta Kamizono2017-09-143-8/+2
| | | | | | | | | | | | | | It is only used `primary_key` and `connection` in the internal, so it is not needed to delegate others to `klass` explicitly. This doesn't change public behavior because `relation` will delegate missing method to `klass`.
* | Don't use `collection.table_name` in `collection_cache_key`Ryuta Kamizono2017-09-142-1/+19
| | | | | | | | | | Because `collection.table_name` doesn't respect table alias. Use `collection.arel_attribute` instead.
* | Don't use `quoted_table_name` in `limited_ids_for`Ryuta Kamizono2017-09-142-2/+8
| | | | | | | | | | | | Because `quoted_table_name` doesn't respect table alias. We should use `arel_attribute` for that, so I added `column_name_from_arel_node` to generate column name from an arel node.
