* Fix deleting through records when using has_many through with `source_type`Ryuta Kamizono2018-01-081-8/+6
| | | | | | | | Currently deleting through records doesn't respect `source_type`. It should not be ignored in that case. Related #23209. Fixes #24116.
* Simply use `scope.delete_all` instead of constructing delete managerRyuta Kamizono2018-01-071-8/+1
|
* Make `find_nth_from_last` more performant when using reversible orderRyuta Kamizono2018-01-071-6/+5
| | | | | We can use `relation.last(index)[-index]` instead of loading all records when using reversible order because `last` will call `reverse_order`.
* Fix `last` with `offset` to behave consistently with loaded relationRyuta Kamizono2018-01-071-1/+1
| | | | | | Currently `last` with `offset` behaves incorrectly because `offset` can not be reversed like `limit`. Therefore, `offset` should also be handled like `limit`.

* Revert commit 4ec5b0d6b4d8a57e034b1014942356e95caf47aa in favor of #28379Ryuta Kamizono2018-01-071-6/+1
| | | | | Commit 4ec5b0d was for fixing the regression #18787, but #28379 fixes #18787 as well. So 4ec5b0d is no longer necessary.

* Partial revert the changing default value of `readonly_value`Ryuta Kamizono2018-01-051-13/+2
| | | | | This is a partial revert of #26182. There is no reason to change the default value.
* Fix newly added reflection order when redefining associationRyuta Kamizono2018-01-041-1/+2
| | | | | | | | | | Currently reflections keeps the order when first added even if when redefining association. As a result of the order, redefining through association which use newly added association will raise `HasManyThroughOrderError`. We need to redefine reflection order as well when redefining association. Fixes #31068.
* Deprecate `valid_alter_table_type?` in sqlite3 adapterRyuta Kamizono2018-01-041-7/+12
| | | | | This method which is used only in the internal was introduced in ac384820 and was renamed in #17579. It does not need to be exposed.
* Correctly handle infinity value in PostgreSQL range typeyuuji.yaginuma2018-01-042-2/+10
| | | | | | | | An empty string is an invalid value in Ruby's range class. So need to handle `Float::INFINITY` as it is and cast it in `encode_range`. Fixes #31612

| * | | Use `count(:all)` in HasManyAssociation#count_recordsKlas Eskilson2017-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Calling `count` on an association can cause invalid SQL queries to be created where the `SELECT COUNT(a, b, c)` function receives multiple columns. This will cause a `StatementInvalid` exception later on. Solution: Use `count(:all)`, which generates a `SELECT COUNT(*)...` query independently of the association. This also includes a test case that, before the fix, broke.

| | | | | | | | | | | | | | | | | | | | Originally I tried to add `assert_equal pk.sql_type, ref.sql_type`. But the assert failed even though the same type due to `sql_type` of primary key in SQLite is upper case. Prefer lower case like other types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | update_attribute previously stopped execution, before saving and before running callbacks, if the record's attributes hadn't changed. [The documentation](http://api.rubyonrails.org/classes/ActiveRecord/Persistence.html#method-i-update_attribute) says that "Callbacks are invoked", which was not happening if the persisted attributes hadn't changed.

This default ENGINE was lost as soon as something was passed in at +options+ option, making its goal and propagation inconsistent, as the programmer needed to remember including ENGINE=InnoDB when something was passed in. This commit removes default ENGINE as its use isn't needed anymore for current MySQL and MariaDB versions. It adds compatibility support and tests to ensure that default ENGINE is still present for migrations with version 5.1 and before. It also ensures we still dump the ENGINE option to +schema.rb+ in order to avoid inconsistencies.

And also, PostgreSQL has a limitation that ORDER BY expressions must appear in select list for SELECT DISTINCT. Therefore, we should not replace custom SELECT list when using `count(:all)` with `distinct`. Closes #31277.

It’s useful with N+1 issues, and to locate stray queries. By default this new option ignores Rails and Ruby code in order to surface only callers from your application Ruby code or your gems. It is enabled on newly generated Rails 5.2 applications and can be enabled on existing Rails applications: ```ruby Rails.application.configure do # ... config.active_record.verbose_query_logs = true end ``` The `rails app:upgrade` task will also add it to `config/development.rb`. This feature purposely avoids coupling with ActiveSupport::BacktraceCleaner since ActiveRecord can be used without ActiveRecord. This decision can be reverted in the future to allow more configurable backtraces (the exclusion of gem callers for example).
