* Remove association(true) references from docs [ci skip]Eugene Kenny2017-10-162-5/+1
| | | | | Passing `true` to force an association to reload its records from the database was deprecated in 5.0 and removed in 5.1.
* Fix longer sequence name detection for serial columns (#28339)Ryuta Kamizono2017-10-154-4/+26
| | | | | | | | We already found the longer sequence name, but we could not consider whether it was the sequence name created by serial type due to missed a max identifier length limitation. I've addressed the sequence name consideration to respect the max identifier length. Fixes #28332.
* MySQL: Don't lose `auto_increment: true` in the `db/schema.rb`Ryuta Kamizono2017-10-151-0/+7
| | | | | | | | | | Currently `AUTO_INCREMENT` is implicitly used in the default primary key definition. But `AUTO_INCREMENT` is not only used for single column primary key, but also for composite primary key. In that case, `auto_increment: true` should be dumped explicitly in the `db/schema.rb`. Fixes #30894.
* Fix `COUNT(DISTINCT ...)` for `GROUP BY` with `ORDER BY` and `LIMIT`Ryuta Kamizono2017-10-141-1/+1
| | | | | | | | | | This is the fix for the regression of #29848. In #29848, I've kept existing select list in the subquery for the count if ORDER BY is given. But it had accidentally affect to GROUP BY queries also. It should keep the previous behavior in that case. Fixes #30886.

(We can assume that a non-builtin adapter was used since these are always available.) * When loading an adapter raises a LoadError, prefix its error message to indicate that the adapter is likely missing an optional dependency.

| | | | | | | | | | | | | | The extra mutation tracker was needed in Rails 5.1 to preserve the old behaviour of `changes`, but now there is no difference between `changes` and `changes_to_save`, so `@mutation_tracker` can be removed.
* | `Postgres::OID::Range` serializes to a `Range`, quote in `Quoting`Thomas Cannon2017-09-262-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PostgreSQL 9.1+ introduced range types, and Rails added support for using this datatype in ActiveRecord. However, the serialization of `PostgreSQL::OID::Range` was incomplete, because it did not properly quote the bounds that make up the range. A clear example of this is a `tsrange`. Normally, ActiveRecord quotes Date/Time objects to include the milliseconds. However, the way `PostgreSQL::OID::Range` serialized its bounds, the milliseconds were dropped. This meant that the value was incomplete and not equal to the submitted value. An example of normal timestamps vs. a `tsrange`. Note how the bounds for the range do not include their milliseconds (they were present in the ruby Range): UPDATE "iterations" SET "updated_at" = $1, "range" = $2 WHERE "iterations"."id" = $3 [["updated_at", "2017-09-23 17:07:01.304864"], ["range", "[2017-09-23 00:00:00 UTC,2017-09-23 23:59:59 UTC]"], ["id", 1234]] `PostgreSQL::OID::Range` serialized the range by interpolating a string for the range, which works for most cases, but does not work for timestamps: def serialize(value) if value.is_a?(::Range) from = type_cast_single_for_database(value.begin) to = type_cast_single_for_database(value.end) "[#{from},#{to}#{value.exclude_end? ? ')' : ']'}" else super end end (byebug) from = type_cast_single_for_database(value.begin) 2010-01-01 13:30:00 UTC (byebug) to = type_cast_single_for_database(value.end) 2011-02-02 19:30:00 UTC (byebug) "[#{from},#{to}#{value.exclude_end? ? ')' : ']'}" "[2010-01-01 13:30:00 UTC,2011-02-02 19:30:00 UTC)" @sgrif (the original implementer for Postgres Range support) provided some feedback about where the quoting should occur: Yeah, quoting at all is definitely wrong here. I'm not sure what I was thinking in 02579b5, but what this is doing is definitely in the wrong place. It should probably just be returning a range of subtype.serialize(value.begin) and subtype.serialize(value.end), and letting the adapter handle the rest. `Postgres::OID::Range` now returns a `Range` object, and `ActiveRecord::ConnectionAdapters::PostgreSQL::Quoting` can now encode and quote a `Range`: def encode_range(range) "[#{type_cast(range.first)},#{type_cast(range.last)}#{range.exclude_end? ? ')' : ']'}" end ... encode_range(range) #=> "['2010-01-01 13:30:00.670277','2011-02-02 19:30:00.745125')" This commit includes tests to make sure the milliseconds are preserved in `tsrange` and `tstzrange` columns
* | Don't generate `foreign_type` if `options[:polymorphic]` is not givenRyuta Kamizono2017-09-271-1/+1
